SpringBoot整合Shiro

介绍

Shiro和SpringSecurity一样是一个安全框架，使用Shiro可以用在JavaSE环境下，也可以用在JavaEE环境，Shiro可以完成：认证、授权、加密、会话管理、与Web集成、缓存等

三个核心组件：Subject, SecurityManager 和 Realms

Subject：即“当前操作用户”。

Subject代表了当前用户的安全操作，SecurityManager则管理所有用户的安全操作。
SecurityManager：它是Shiro 框架的核心，典型的Facade 模式，Shiro通过SecurityManager来管理内部组件实例，并通过它来提供安全管理的各种服务。
Realm： Realm充当了Shiro与应用安全数据间的“桥梁”或者“连接器”。也就是说，当对用户执行认证（登
录）和授权（访问控制）验证时，Shiro会从应用配置的Realm中查找用户及其权限信息。

整合SpringBoot

创建SpringBoot项目，勾选web

添加依赖

<!--shiro安全管理-->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.7.1</version>
</dependency>
<!-- Thymeleaf依赖 -->
<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-java8time</artifactId>
</dependency>
<!--thymeleaf依赖-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

创建html页面

controller

package com.sheep.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class MyController {

    @RequestMapping({"/","/index"})
    public String toIndex(Model model){
        model.addAttribute("msg","hello,shiro");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }

    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }

    @RequestMapping("/toLogin")
    public String toLogin(){
        return "login";
    }

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        /*获取当前用户*/
        Subject subject = SecurityUtils.getSubject();
        /*封装用户的登入数据*/
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        /*执行登入的方法,如果没有异常说明ok,捕获异常*/
        try {
            subject.login(token);
            return "index";
        } catch (UnknownAccountException e) {
            model.addAttribute("msg","用户名为空!!!");
            return "login";
        } catch (IncorrectCredentialsException e){
            model.addAttribute("msg","密码为空!!!");
            return "login";
        }
    }
    @RequestMapping("/noauth")
    @ResponseBody
    public String unauthorized(){
        return "未经授权无法访问此页面！！！";
    }
}

要使用shiro需要自定义Realm的授权和认证

package com.sheep.config;

import com.sheep.pojo.User;
import com.sheep.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;

/*自定义UserRealm*/
public class UserRealm extends AuthorizingRealm {

    @Autowired
    UserService userService;

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了=>授权(doGetAuthorizationInfo)");
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //给所有人添加user:add权限
		info.addStringPermission("user:add");
        return info;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了=>认证(doGetAuthenticationInfo)");
        /*
         * 用户名、密码、数据库中取
         * */
        /*
         * 自定义数据库
         * */
        String name="root";
        String password="123456";
        UsernamePasswordToken userToken = (UsernamePasswordToken) token;
        if(!userToken.getUsername().equals(name)){
            return null;/*用户名错误,shiro自动抛出异常;密码认证shiro自动认证*/
        }
        /*密码认证,Shiro会自动密码认证*/
        return new SimpleAuthenticationInfo("",password,"");
    }
}

shiro配置类

package com.sheep.config;

import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;
import java.util.Map;

@Configuration
public class ShiroConfig {
    /**
     * 1、创建自定义的realm对象
     * 2、DafaultWebSecurityManager
     * 3、ShiroFilterFactoryBean

    /*自定义的realm对象*/
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
    /*DafaultWebSecurityManager*/
    @Bean
    public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }
    /*ShiroFilterFactoryBean*/
    @Bean
    public ShiroFilterFactoryBean getsShiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //过滤请求
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        /*添加shiro的内置过滤器*/
        /*
         * anno:无需认证可以访问
         * authc:必须认证才能访问
         * user:必须拥有记住我功能才能访问
         * perms:拥有对某个资源的权限才能访问
         * role:拥有某个角色权限才能访问
         * */
        Map<String, String> filterMap = new LinkedHashMap<>();
        //授权
        filterMap.put("/user/add","perms[user:add]");
       	//方法一
        //filterMap.put("/user/add","authc");
        //filterMap.put("/user/update","authc");
        //方法二
        filterMap.put("/user/*","authc");
        bean.setFilterChainDefinitionMap(filterMap);
        /*设置登入请求*/
        bean.setLoginUrl("/toLogin");
        /*设置未授权页面*/
        bean.setUnauthorizedUrl("/noauth");
        return bean;
    }
}

创建表

+----------+-------------+------+-----+---------+----------------+
| Field    | Type        | Null | Key | Default | Extra          |
+----------+-------------+------+-----+---------+----------------+
| id       | int         | NO   | PRI | NULL    | auto_increment |
| username | varchar(5)  | YES  |     | NULL    |                |
| password | varchar(6)  | YES  |     | NULL    |                |
| perms    | varchar(20) | YES  |     | NULL    |                |
+----------+-------------+------+-----+---------+----------------+

创建表对应的实体类

package com.sheep.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int id;
    private String username;
    private String password;
    private String perms;
}

创建接口

package com.sheep.mapper;

import com.sheep.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

@Mapper
@Repository
public interface UserMapper {
    public User queryUserByName(String username);
}

service层接口

package com.sheep.service;

import com.sheep.pojo.User;

public interface UserService {
    public User queryUserByName(String username);
}

service实现接口

package com.sheep.service;

import com.sheep.mapper.UserMapper;
import com.sheep.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;

    @Override
    public User queryUserByName(String username) {
        return userMapper.queryUserByName(username);
    }
}

测试连接数据库是否成功

package com.sheep;

import com.sheep.service.UserServiceImpl;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class DemoApplicationTests {

    @Autowired
    UserServiceImpl userService;

    @Test
    void contextLoads() {
        System.out.println(userService.queryUserByName("root"));
    }
}

在resources文件夹下创建mapper.XML文件

<mapper namespace="com.sheep.mapper.UserMapper">
    <select id="queryUserByName" parameterType="String" resultType="com.sheep.pojo.User">
        select * from user where username = #{username}
    </select>
</mapper>

application.properties配置连接数据库信息

# 配置数据库信息
spring.datasource.username=root
spring.datasource.password=123321
spring.datasource.url=jdbc:mysql://localhost:3306/junit?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
# mybatis配置文件
mybatis.type-aliases-package=com.sheep.pojo
mybatis.mapper-locations=classpath:mapper/*.XML
