从零学习SpringSecurity
一、简介
SpringSecurity是一个功能强大且高度可定制的身份验证和访问控制框架,和spring项目整合更加方便。
二、核心功能
- 认证(Authentication):指的是验证某个用户能否访问该系统。
- 授权(Authorization):指的是验证某个用户是否有权限执行某个操作。
三、搭建v1.0版本
1、新建一个springboot项目
myspringsecurity
2、添加maven依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
3、新建一个test的controller
package com.zb.myspringsecurity.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/demo")
public class DemoController {
@RequestMapping("/hello")
public String hello() {
return "hello world";
}
}
4、启动项目
MyspringsecurityApplication.main();
5、用浏览器测试
http://localhost:8080/demo/hello
我们会发现浏览器会跳转到login页面,如下图
6、密码登陆
我们可以在项目启动日志里面找到密码
2021-07-19 10:58:48.558 INFO 5244 --- [ main] .s.DelegatingFilterProxyRegistrationBean : Mapping filter: 'springSecurityFilterChain' to: [/*]

- 用户名是:user
- 密码(从日志找到)是:ced4127a-1677-438e-a65b-2ab219137083
登录成功如下图:
二、进阶版v2.0(配置文件配置用户密码)
1、配置文件里面写用户名密码
刚才的密码生成在日志里面了,实际使用很不方便,可以把密码用户名固定配置一下
spring.security.user.name=admin
spring.security.user.password=123
- 重新启动项目,会发现没有生成密码的日志了
- 测试用新的用户名密码没问题
三、v3.0(java类里面写用户名密码)
1、在java类里面配置用户名密码
刚才是写在配置文件里面,我们还可以写到java类里面
package com.zb.myspringsecurity.config.security;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
@EnableWebSecurity
public class ZbWebSecurityConfigurer extends WebSecurityConfigurerAdapter {
@Bean
PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("zhangsan")
.password(passwordEncoder().encode("123"))
.roles("ADMIN")
.and()
.withUser("lisi")
.password(passwordEncoder().encode("123"))
.roles("ADMIN")
.and()
.withUser("wangwu")
.password(passwordEncoder().encode("123"))
.roles("ADMIN")
;
}
}
我们再重启项目测试一下,发现用三个用户名密码都没问题。
四、v4.0(ignore url)
1、修改上面的java类,增加两个方法
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers(
//"/**/*.html",
"/**/*.js",
"/**/*.css",
"/**/*.ico",
"/**/*.jpg",
"/**/*.png",
"/test/**" // 忽略test
);
}
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin()
.and()
.httpBasic();
}
- 我们配置了ignore的url
- 我们再加一个controller用来测试
package com.zb.myspringsecurity.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/test")
public class TestController {
@RequestMapping("/test")
public String hello() {
return "hello test";
}
}
- 注意我们上面的ignore里面有:"/test/**"
- 也就是说TestController 不会有登录校验
重启项目测试一下没问题
五、v5.0(在数据库里面配置用户名密码)
1、新建mysql库
create database myspringsecurity CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
create user securityuser IDENTIFIED by 'securitypass';
grant all privileges on myspringsecurity.* to securityuser@localhost identified by 'securitypass';
flush privileges;
2、新建用户表和角色表
DROP TABLE IF EXISTS `tb_user`;
CREATE TABLE `tb_user` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_name` varchar(50) DEFAULT NULL,
`password` varchar(100) DEFAULT NULL,
`mobile` int(11) DEFAULT NULL,
`sex` int(2) DEFAULT NULL,
`email` varchar(50) DEFAULT NULL,
`status` int(2) DEFAULT NULL,
`create_time` DATE DEFAULT NULL,
`create_id` int(11) DEFAULT NULL,
`update_time` date DEFAULT NULL,
`update_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `tb_role`;
CREATE TABLE `tb_role` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`role_name` varchar(50) DEFAULT NULL,
`status` int(2) DEFAULT NULL,
`create_time` DATE DEFAULT NULL,
`create_id` int(11) DEFAULT NULL,
`update_time` date DEFAULT NULL,
`update_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `tr_user_role`;
CREATE TABLE `tr_user_role` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_id` bigint(20) DEFAULT NULL,
`role_id` bigint(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
3、初始化一些数据
insert into `tb_user` (id, user_name, password) values (1, 'zhangsan', '123');
insert into `tb_user` (id, user_name, password) values (2, 'lisi', '123');
insert into `tb_user` (id, user_name, password) values (3, 'wangwu', '123');
insert into `tb_role` (id, role_name) values (1, '系统管理员');
insert into `tb_role` (id, role_name) values (2, '一般操作员');
insert into `tr_user_role` (id, user_id, role_id) values (1, 1, 1);
insert into `tr_user_role` (id, user_id, role_id) values (2, 1, 2);
insert into `tr_user_role` (id, user_id, role_id) values (3, 2, 2);
4、加入maven依赖
我们这里用了mybatis-plus。
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.44</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.1.2</version>
</dependency>
5、引入mybatis-plus自动生成代码的依赖
<!-- mybatis-plus代码生成 -->
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.29</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.1.2</version>
</dependency>
6、修改代码生成类
package com.zb.myspringsecurity.config.mybatis;
import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.ArrayList;
import java.util.List;
public class MybatisGenerator {
public static void main(String[] args) {
AutoGenerator mpg = new AutoGenerator();
// 全局配置
GlobalConfig gc = new GlobalConfig();
final String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
gc.setAuthor("system");
gc.setOpen(false);
gc.setFileOverride(true);
gc.setBaseResultMap(true);
// gc.setSwagger2(true); 实体属性 Swagger2 注解
mpg.setGlobalConfig(gc);
// 数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://127.0.0.1:3306/myspringsecurity?useUnicode=true&useSSL=false&characterEncoding=utf8");
// dsc.setSchemaName("public");
dsc.setDriverName("com.mysql.jdbc.Driver");
dsc.setUsername("securityuser");
dsc.setPassword("securitypass");
mpg.setDataSource(dsc);
// 包配置
PackageConfig pc = new PackageConfig();
pc.setParent("com.zb.myspringsecurity");
mpg.setPackageInfo(pc);
// 自定义配置
InjectionConfig cfg = new InjectionConfig() {
@Override
public void initMap() {
// to do nothing
}
};
// 如果模板引擎是 freemarker
String templatePath = "/templates/mapper.xml.ftl";
// 如果模板引擎是 velocity
// String templatePath = "/templates/mapper.xml.vm";
// 自定义输出配置
List<FileOutConfig> focList = new ArrayList<>();
// 自定义配置会被优先输出
focList.add(new FileOutConfig(templatePath) {
@Override
public String outputFile(TableInfo tableInfo) {
// 自定义输出文件名 , 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化!!
return projectPath + "/src/main/resources/mapper/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
// 配置模板
TemplateConfig templateConfig = new TemplateConfig();
templateConfig.setXml(null);
mpg.setTemplate(templateConfig);
// 策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setNaming(NamingStrategy.underline_to_camel);
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
// strategy.setSuperEntityClass("com.baomidou.ant.common.BaseEntity");
strategy.setEntityLombokModel(true);
strategy.setRestControllerStyle(false);
// 公共父类
// strategy.setSuperControllerClass("com.baomidou.ant.common.BaseController");
// 写于父类中的公共字段
// strategy.setSuperEntityColumns("id");
strategy.setInclude("tb_user","tb_role","tr_user_role");
// strategy.setControllerMappingHyphenStyle(true);
strategy.setTablePrefix("tb_", "tr_");
mpg.setStrategy(strategy);
mpg.setTemplateEngine(new FreemarkerTemplateEngine());
mpg.execute();
}
}
- 执行生成mapper,service和controller
- mybatis准备好了,可以修改security配置了
7、修改configure方法
原先的:
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("zhangsan")
.password(passwordEncoder().encode("123"))
.roles("ADMIN")
.and()
.withUser("lisi")
.password(passwordEncoder().encode("123"))
.roles("ADMIN")
.and()
.withUser(passwordEncoder().encode("123"))
.password("123")
.roles("ADMIN")
;
}
改成新的:
@Autowired
ZxUserDetailsServiceImpl zxUserDetailsService;
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(zxUserDetailsService);
}
8、新增ZxUserDetailsServiceImpl类
package com.zb.myspringsecurity.config.security;
import com.zb.myspringsecurity.entity.Role;
import com.zb.myspringsecurity.entity.User;
import com.zb.myspringsecurity.entity.UserRole;
import com.zb.myspringsecurity.service.IUserRoleService;
import com.zb.myspringsecurity.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
import org.springframework.util.Assert;
import org.springframework.util.CollectionUtils;
import java.util.ArrayList;
import java.util.List;
@Component
public class ZxUserDetailsServiceImpl implements UserDetailsService {
@Autowired
PasswordEncoder passwordEncoder;
@Autowired
IUserService iUserService;
@Autowired
IUserRoleService iUserRoleService;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
/**
// DEMO:
List<SimpleGrantedAuthority> authorityList = new ArrayList<>();
authorityList.add(new SimpleGrantedAuthority("Admin"));
ZxUser zxUser = new ZxUser();
zxUser.setUserName("zhangsanfeng");
zxUser.setPassword(passwordEncoder.encode("123"));
zxUser.setAuthorities(authorityList);
return zxUser;
*/
List<User> userList = iUserService.lambdaQuery().eq(User::getUserName, username).list();
if (CollectionUtils.isEmpty(userList)) {
throw new UsernameNotFoundException("不存在的用户");
}
User user = userList.get(0);
ZxUser zxUser = new ZxUser();
zxUser.setUserName(user.getUserName());
zxUser.setPassword(passwordEncoder.encode(user.getPassword()));
zxUser.setId(user.getId());
List<UserRole> userRoleList = iUserRoleService.lambdaQuery().eq(UserRole::getUserId, zxUser.getId()).list();
List<SimpleGrantedAuthority> authorityList = new ArrayList<>();
if (!CollectionUtils.isEmpty(userRoleList)) {
for (UserRole userRole : userRoleList) {
authorityList.add(new SimpleGrantedAuthority(String.valueOf(userRole.getRoleId())));
}
}
zxUser.setAuthorities(authorityList);
return zxUser;
}
}
9、新增自定义user
package com.zb.myspringsecurity.config.security;
import com.zb.myspringsecurity.entity.User;
import lombok.Data;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.Collection;
@Data
public class ZxUser extends User implements UserDetails {
private Collection<? extends GrantedAuthority> authorities;
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return authorities;
}
@Override
public String getPassword() {
return super.getPassword();
}
@Override
public String getUsername() {
return super.getUserName();
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
}
10、验证
重启服务,用数据库里面的用户和密码验证没问题。
六、v6.0(实现前后端分离,token校验)
1、引入认证管理器 bean
/**
* 认证管理器
* @return
* @throws Exception
*/
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
2、写一个统一的登录接口
package com.zb.myspringsecurity.controller;
import com.zb.myspringsecurity.config.security.ZxUser;
import com.zb.myspringsecurity.config.security.ZxUserDetailsServiceImpl;
import com.zb.myspringsecurity.config.vo.CommonResponse;
import com.zb.myspringsecurity.config.vo.LoginParamVo;
import com.zb.myspringsecurity.config.vo.TokenVo;
import com.zb.myspringsecurity.service.TokenService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
@Slf4j
@RestController
@RequestMapping("/login")
public class LoginController {
@Autowired
private AuthenticationManager authenticationManager;
@Resource
ZxUserDetailsServiceImpl userDetailsService;
@Resource
TokenService tokenService;
@RequestMapping("/login-in")
public CommonResponse<TokenVo> login(@RequestBody LoginParamVo loginParamVo) {
try {
// 1 创建UsernamePasswordAuthenticationToken
UsernamePasswordAuthenticationToken token
= new UsernamePasswordAuthenticationToken(loginParamVo.getUsername(), loginParamVo.getPassword());
// 2 认证
Authentication authentication = this.authenticationManager.authenticate(token);
// 3 保存认证信息
SecurityContextHolder.getContext().setAuthentication(authentication);
// 4 加载UserDetails
ZxUser zxUser = this.userDetailsService.loadUserByUsername(loginParamVo.getUsername());
// 5 生成自定义token
TokenVo tokenVo = tokenService.createToken(zxUser);
return CommonResponse.successWithData(tokenVo);
} catch (Exception e) {
return CommonResponse.fail(401, e.getMessage());
}
}
}
3、tokenservice
package com.zb.myspringsecurity.service;
import com.zb.myspringsecurity.config.vo.TokenVo;
import org.springframework.security.core.userdetails.UserDetails;
public interface TokenService {
TokenVo createToken(UserDetails details);
boolean verifyToken(String token);
String getUserNameByToken(String token);
}
简单的实现:
package com.zb.myspringsecurity.service.impl;
import com.zb.myspringsecurity.config.vo.TokenVo;
import com.zb.myspringsecurity.service.TokenService;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Service;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
@Service
public class TokenServiceImpl implements TokenService {
// todo 可以存redis, 设置过期时间
private static final Map<String, String> tokenMap = new HashMap<>();
@Override
public TokenVo createToken(UserDetails details) {
String token = UUID.randomUUID().toString();
tokenMap.put(token, details.getUsername());
TokenVo tokenVo = new TokenVo();
tokenVo.setToken(token);
tokenVo.setExpireTime(60*60);
return tokenVo;
}
@Override
public boolean verifyToken(String token) {
return tokenMap.get(token) != null;
}
@Override
public String getUserNameByToken(String token) {
return tokenMap.get(token);
}
}
- 创建token, 校验token, 根据token获取username
- 存的是token和username的关系
4、修改校验方式
修改为:SessionCreationPolicy.STATELESS
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
.csrf().disable()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.formLogin()
.and()
.httpBasic()
;
}
5、增加一个校验token的filter
@Autowired
ZbTokenAuthenticationFilter zbTokenAuthenticationFilter;
httpSecurity.addFilterBefore(zbTokenAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
filter:
package com.zb.myspringsecurity.config.security.customer;
import com.zb.myspringsecurity.config.security.ZxUser;
import com.zb.myspringsecurity.config.security.ZxUserDetailsServiceImpl;
import com.zb.myspringsecurity.service.IUserRoleService;
import com.zb.myspringsecurity.service.TokenService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.authentication.WebAuthenticationDetailsSource;
import org.springframework.stereotype.Service;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Service
public class ZbTokenAuthenticationFilter extends OncePerRequestFilter {
@Autowired
TokenService tokenService;
@Autowired
IUserRoleService iUserRoleService;
@Autowired
ZxUserDetailsServiceImpl userDetailsService;
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
logger.info("TokenAuthenticationFilter.doFilterInternal start ...");
String token = request.getHeader("token");
if (token == null || "".equals(token)) {
logger.info("token is null , return .");
filterChain.doFilter(request, response);
return;
}
if (SecurityContextHolder.getContext().getAuthentication() != null) {
filterChain.doFilter(request, response);
return;
}
boolean result = tokenService.verifyToken(token);
if (!result) {
logger.info("ssoService.verifyToken not pass , return .");
filterChain.doFilter(request, response);
return;
}
ZxUser zxUser = userDetailsService.loadUserByUsername(tokenService.getUserNameByToken(token));
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(
zxUser, null, zxUser.getAuthorities());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
logger.info("token valid pass , username : " + zxUser.getUsername());
SecurityContextHolder.getContext().setAuthentication(authentication);
filterChain.doFilter(request, response);
}
}
- 至此,我们已经把项目改造成前后端分离的了
- 有数据库用户密码登录
- 有登录生成token
- 有校验url, header必须包含token
七、v7.0(权限控制)
我们上面已经把spring security的一个核心功能(认证)说完了,下面我们说授权。
1、增加权限表,关联表
DROP TABLE IF EXISTS `tb_permission`;
CREATE TABLE `tb_permission` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`en_name` varchar(50) DEFAULT NULL,
`cn_name` varchar(50) DEFAULT NULL,
`create_time` DATE DEFAULT NULL,
`create_id` int(11) DEFAULT NULL,
`update_time` date DEFAULT NULL,
`update_id` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
DROP TABLE IF EXISTS `tr_role_permission`;
CREATE TABLE `tr_role_permission` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`role_id` bigint(20) DEFAULT NULL,
`permission_id` bigint(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
2、初始化数据
insert into `tb_permission` (id, en_name, cn_name) values (1, 'system:user:read', '可读');
insert into `tb_permission` (id, en_name, cn_name) values (2, 'system:user:edit', '可修改');
insert into `tr_role_permission` (id, role_id, permission_id) values (1, 1, 1);
insert into `tr_role_permission` (id, role_id, permission_id) values (2, 1, 2);
insert into `tr_role_permission` (id, role_id, permission_id) values (3, 2, 1);
3、修改ZxUser
增加permissionSet
@Data
public class ZxUser extends User implements UserDetails {
...
private Set<String> permissionSet;
...
}
4、修改loadUserByUsername方法
增加权限查询部分:
@Override
public ZxUser loadUserByUsername(String username) throws UsernameNotFoundException {
List<User> userList = iUserService.lambdaQuery().eq(User::getUserName, username).list();
if (CollectionUtils.isEmpty(userList)) {
throw new UsernameNotFoundException("不存在的用户");
}
User user = userList.get(0);
ZxUser zxUser = new ZxUser();
zxUser.setUserName(user.getUserName());
zxUser.setPassword(passwordEncoder.encode(user.getPassword()));
zxUser.setId(user.getId());
List<SimpleGrantedAuthority> authorityList = new ArrayList<>();
// role
List<UserRole> userRoleList = iUserRoleService.lambdaQuery().eq(UserRole::getUserId, zxUser.getId()).list();
if (!CollectionUtils.isEmpty(userRoleList)) {
for (UserRole userRole : userRoleList) {
authorityList.add(new SimpleGrantedAuthority(String.valueOf(userRole.getRoleId())));
}
// permission
List<Long> roleIdList = userRoleList.stream().map(UserRole::getRoleId).collect(Collectors.toList());
List<RolePermission> rolePermissionList = iRolePermissionService.lambdaQuery()
.in(RolePermission::getRoleId, roleIdList).list();
if (!CollectionUtils.isEmpty(rolePermissionList)) {
Collection<Permission> permissionList = iPermissionService
.listByIds(rolePermissionList.stream()
.map(RolePermission::getPermissionId).collect(Collectors.toList()));
Set<String> permissionSet = permissionList.stream().map(Permission::getEnName).collect(Collectors.toSet());
zxUser.setPermissionSet(permissionSet);
}
}
zxUser.setAuthorities(authorityList);
return zxUser;
}
5、我们实现一个自己的权限控制类
package com.zb.myspringsecurity.config.security.customer;
import com.zb.myspringsecurity.config.security.ZxUser;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.access.PermissionEvaluator;
import org.springframework.security.core.Authentication;
import org.springframework.stereotype.Component;
import java.io.Serializable;
import java.util.Set;
@Slf4j
@Component
public class ZbPermissionEvaluator implements PermissionEvaluator {
@Override
public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {
ZxUser user = (ZxUser) authentication.getPrincipal();
Set<String> permissonSet = user.getPermissionSet();
if (permission == null) {
log.info("permission valid not pass , permission is null");
return false;
}
if (permissonSet.contains(permission.toString())) {
log.info("permission valid pass , permission : {}", permission.toString());
return true;
}
log.info("permission valid not pass , permission : {}", permission.toString());
return false;
}
@Override
public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) {
return false;
}
}
- 很简单,就是判断权限集合存不存在当前权限
6、配置使之生效
@Autowired
ZbPermissionEvaluator zbPermissionEvaluator;
@Bean
public DefaultWebSecurityExpressionHandler defaultWebSecurityExpressionHandler() {
DefaultWebSecurityExpressionHandler defaultWebSecurityExpressionHandler = new DefaultWebSecurityExpressionHandler();
defaultWebSecurityExpressionHandler.setPermissionEvaluator(zbPermissionEvaluator);
return defaultWebSecurityExpressionHandler;
}
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
...
httpSecurity.authorizeRequests().expressionHandler(defaultWebSecurityExpressionHandler());
...
}
7、测试类
package com.zb.myspringsecurity.controller;
import com.zb.myspringsecurity.entity.User;
import com.zb.myspringsecurity.service.IUserService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
@Slf4j
@RestController
@RequestMapping("/user")
public class UserController {
@Autowired
IUserService iUserService;
@PreAuthorize("hasPermission('UserController', 'system:user:read')")
@RequestMapping("/list")
public List<User> list(HttpServletRequest request) {
log.info("session id: {}" , request.getSession().getId());
return iUserService.list();
}
}
8、启动服务测试
- 注意:我们上面的/user/list, 配置了'system:user:read'权限
- 仔细去看我们初始化的数据库数据,会发现wangwu是没有任何角色的,也没有任何权限
- 所以,wangwu 不能访问/user/list
先测试zhangsan:
POST http://localhost:8080/login/login-in
Accept: */*
Cache-Control: no-cache
content-type:application/json
{"username":"zhangsan", "password":"123"}
返回:
{
"data": {
"token": "e048ba23-7061-43d6-ab35-7c2eb93acda8",
"expireTime": 3600
},
"code": 200,
"msg": "ok"
}
用这个token去请求/user/list
GET http://localhost:8080/user/list
Accept: application/json
token: e048ba23-7061-43d6-ab35-7c2eb93acda8
返回:
[
{
"id": 1,
"userName": "zhangsan",
"password": "123",
"mobile": null,
"sex": null,
"email": null,
"status": null,
"createTime": null,
"createId": null,
"updateTime": null,
"updateId": null
},
{
"id": 2,
"userName": "lisi",
"password": "123",
"mobile": null,
"sex": null,
"email": null,
"status": null,
"createTime": null,
"createId": null,
"updateTime": null,
"updateId": null
},
{
"id": 3,
"userName": "wangwu",
"password": "123",
"mobile": null,
"sex": null,
"email": null,
"status": null,
"createTime": null,
"createId": null,
"updateTime": null,
"updateId": null
}
]
- 用同样的方法测试lisi和wangwu,lisi可以访问,wangwu不可以,返回如下
{
"timestamp": "2021-07-19T06:53:38.833+0000",
"status": 500,
"error": "Internal Server Error",
"message": "No message available",
"path": "/user/list"
}
- 当然你还可以统一你的异常回复信息,可以自行研究
- 至此,我们的权限控制也实现了
八、总结
- 至此,我们的认证和鉴权都说完了
- 以上只是一种实现,spring security支持自定义扩展,还有其它实现方式,可以自己研究
