springboot整合shiro
springboot整合shiro
1、springboot整合shiro环境搭建
1.1、导入依赖
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.7.1</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
<version>2.5.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.7.1</version>
</dependency>
1.2、首页index.xml搭建
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>首页</h1>
<p th:text="${msg}"></p>
<a th:href="@{/user/add}">add</a> | <a th:href="@{/user/update}">update</a>
</body>
</html>
1.3、controller搭建
@Controller
public class MyController {
@RequestMapping({"/","/index"})
public String toIndex(Model model){
model.addAttribute("msg","hello shiro");
return "index";
}
}
1.4、创建ShiroConfig
@Configuration
public class ShiroController {
//ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean filterFactoryBean = new ShiroFilterFactoryBean();
//设置安全管理器
filterFactoryBean.setSecurityManager(defaultWebSecurityManager);
return filterFactoryBean;
}
//DefaultWebSecurityManager
@Bean(name = "securityManager")
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//关联UserRealm
securityManager.setRealm(userRealm);
return securityManager;
}
//创建 realm 对象 需要自定义
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
}
1.5、创建UserRealm
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行===>AuthorizationInfo");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行===>AuthenticationToken");
return null);
}
}
1.6、add和update页面创建
add.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>add</h1>
</body>
</html>
update
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>update</h1>
</body>
</html>
1.7、add和update配置
@RequestMapping("/user/add")
public String add(){
return "user/add";
}
@RequestMapping("/user/update")
public String update(){
return "user/update";
}
2、Shiro实现登录拦截
2.1、ShiroConfig登录拦截信息完善
//ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean filterFactoryBean = new ShiroFilterFactoryBean();
//设置安全管理器
filterFactoryBean.setSecurityManager(defaultWebSecurityManager);
//添加shiro的内置过滤器
/*
anon: 无需认证就可以访问
authc: 必须认证才能访问
user: 必须拥有 记住我 功能才能用
perms: 拥有对某个资源的权限才能用
role: 拥有某个角色权限才能访问
*/
Map<String, String> filterMap = new LinkedHashMap<>();
filterMap.put("/user/add","authc");
filterMap.put("/user/update","authc");
filterFactoryBean.setFilterChainDefinitionMap(filterMap);
return filterFactoryBean;
}
2.2、表单
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<p>登录</p>
<hr>
<form th:action="@{/login}">
<p>用户名:<input type="text" name="username"></p>
<p>密码 :<input type="password" name="password"></p>
<p><input type="submit"></p>
</form>
</body>
</html>
2.3、配置
@RequestMapping("/toLogin")
public String toLogin(){
return "login";
}
3、Shiro实现用户认证
3.1、用户认证信息
@RequestMapping("/login")
public String login(String username,String password,Model model){
//获取当前的用户
Subject subject = SecurityUtils.getSubject();
//封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
try{
subject.login(token);
return "index"; //执行登录方法，如果没有异常就说明ok
}catch (UnknownAccountException e){
model.addAttribute("msg","用户名错误");//用户名不存在
return "login";
}catch (IncorrectCredentialsException e){
model.addAttribute("msg","密码错误");//密码不存在
return "login";
}
}
3.2、表单完善
<p th:text="${msg}" style="color: red"></p>
3.3、用户名密码验证
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行===>AuthenticationToken");
String name = "root";
String password = "123456";
UsernamePasswordToken userToken = (UsernamePasswordToken) token;
if(!userToken.getUsername().equals(name)){
return null;
}
//密码认证
return new SimpleAuthenticationInfo(
"",user.getPwd(),"");
}
4、Shiro整合Mybatis
4.1、导入依赖
<!--mysql-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.25</version>
</dependency>
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>

</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.20</version>
</dependency>
4.2、application.yml配置
spring:
datasource:
username: root
password: 123456
#?serverTimezone=UTC解决时区的报错
url: jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
driver-class-name: com.mysql.cj.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
#Spring Boot 默认是不注入这些属性值的，需要自己绑定
#druid 数据源专有配置
initialSize: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
#配置监控统计拦截的filters，stat:监控统计、log4j：日志记录、wall：防御sql注入
#如果允许时报错 java.lang.ClassNotFoundException: org.apache.log4j.Priority
#则导入 log4j 依赖即可，Maven 地址：https://mvnrepository.com/artifact/log4j/log4j
filters: stat,wall,log4j
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
4.3、application.properties配置
mybatis.type-aliases-package=com.wang.pojo
mybatis.mapper-locations=classpath:mapper/*.xml
4.4、实体类user
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String pwd;
private String perms;
}
4.5、mapper类
@Repository
@Mapper
public interface UserMapper {
public User queryUserByName(String name);
}
4.6、UserMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.wang.mapper.UserMapper">
<select id="queryUserByName" parameterType="String" resultType="User">
select * from mybatis.user where name = #{name}
</select>
</mapper>
4.7、service层
public interface UserService {
public User queryUserByName(String name);
}
@Service
public class UserServiceImpl implements UserService {
@Autowired
UserMapper userMapper;
@Override
public User queryUserByName(String name) {
return userMapper.queryUserByName(name);
}
}
4.8、测试类
@SpringBootTest
class Shiro02SpringbootApplicationTests {
@Autowired
UserServiceImpl userService;
@Test
void contextLoads() {
System.out.println(userService.queryUserByName("牛奶糖"));
}
}
4.9、连接真实数据库
@Autowired
UserServiceImpl userService;
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行===>AuthenticationToken");
//用户名认证
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
//连接真实数据库
User user = userService.queryUserByName(userToken.getUsername());
if(user==null){
return null;
}
Subject subject = SecurityUtils.getSubject();
Session session = subject.getSession();
session.setAttribute("loginUser","user");
//密码认证
return new SimpleAuthenticationInfo(
user,user.getPwd(),"");
}
5、Shiro请求授权实现
5.1、授权设置
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行===>AuthorizationInfo");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//授权
filterMap.put("/user/add","perms[user:add]");
filterMap.put("/user/update","perms[user:update]");
filterMap.put("/user/*","authc");
filterFactoryBean.setFilterChainDefinitionMap(filterMap);
//设置未经授权的请求
filterFactoryBean.setUnauthorizedUrl("/unauthor");
//设置登录的请求
filterFactoryBean.setLoginUrl("/toLogin");
return filterFactoryBean;
}
5.2、未授权的请求
@RequestMapping("/unauthor")
@ResponseBody
public String Unauthorized(){
return "未经授权无法访问此页面";
}
5.3、设置当前用户权限
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行===>AuthorizationInfo");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// info.addStringPermission("user:add");
//拿到当前登录的对象
Subject subject = SecurityUtils.getSubject();
User currentUser = (User) subject.getPrincipal();
//设置当前用户的权限
info.addStringPermission(currentUser.getPerms());
return info;
}
