Spring Boot集成Shiro权限管理

Bertha 。 2021-12-08 17:47 406阅读 0赞

# **前言：** #

**简述：权限管理分为认证和授权两大部分**

**认证即为登录认证，授权即为访问某API时是否有权限访问**

原理图解

*  Suject：前台传值过来的对象
 *  SecurityManager：权限管理核心对象
 *  Authenticator：权限认证对象
 *  Authorizer：权限授权对象
 *  SessionManager：session管理对象
 *  Realm：与数据库连接的桥梁对象
 *  ShiroUtils：此工具类可以连接以上的对象

# 一、数据表建立 #

**数据表：用户表、用户角色中间表、角色表、角色权限中间表、权限表**

# **二 、项目搭建** #

### **1、项目目录结构：** ###

## ##

### **2、添加依赖，主要是shiro依赖，而swagger-ui用于测试接口** ###

        </dependencies>

### **3、配置yml文件** ###

#配置mysql
    spring:
      datasource:
        url: jdbc:mysql://localhost:3306/shiro?serverTimezone=GMT
        driver-class-name: com.mysql.cj.jdbc.Driver
        username: root
        password: 123456
    #配置mybatis-plus
    mybatis-plus:
      mapper-locations: classpath:/mybatis/mapper/*.xml
    #显示sql语句
    logging:
      level:
        cn.zdxh.shirodemo.mapper: DEBUG

## ##

### **4、首先定义一个统一返回json的包装类** ###

**Result**

package cn.zdxh.shirodemo.utils;
    
    import lombok.Data;
    
    @Data
    public class Result<T> {
        private Integer code;
        private String msg;
        private T data;
    
        public static <T> Result success(T t){
            Result<T> result = new Result();
            result.setCode(1);
            result.setMsg("成功");
            result.setData(t);
            return result;
        }
    
        public static <T> Result error(T t){
            Result result = new Result();
            result.setCode(0);
            result.setMsg("失败");
            result.setData(t);
            return result;
        }
    }

## ##

### **5、Shiro加密工具类** ###

**ShiroUtils**

package cn.zdxh.shirodemo.utils;
    
    import org.apache.shiro.crypto.hash.Md5Hash;
    
    public class ShiroUtils {
    
        //密码加密
        public static String encryptMD5(String password){
            return new Md5Hash(password).toString();
        }
    
        //通过MD5加盐加密
        public static String encryptMD5(String password,String salt){
            return new Md5Hash(password,salt).toString();
        }
    }

## ##

### **6、定义实体类** ###

*  这里只给出一个SysUser实体类，其他实体类的同理。
 *  需要注意的是本项目用的是mybatis-plus做持久层，要给实体类指定自增ID策略

**SysUser**

package cn.zdxh.shirodemo.entity;
    
    import com.baomidou.mybatisplus.annotations.TableId;
    import com.baomidou.mybatisplus.enums.IdType;
    import lombok.Data;
    
    import java.util.Date;
    
    /**
     * 用户实体
     */
    @Data
    public class SysUser {
      //ID自动增长策略
      @TableId(value = "id", type = IdType.AUTO)
      private Integer id;
      private String username;
      private String password;
      private String salt;
      private Integer createUserId;
      private Date createTime;
    
    
    }

### **7、持久层Mapper** ###

*  只给出SysUserMapper持久层相关，其他表的持久层同理
 *  继承BaseMapper即可完成简单的crud
 *  认证：需要查询出用户的信息
 *  授权：需要查询角色和权限的信息

**SysUserMapper**

package cn.zdxh.shirodemo.mapper;
    
    import cn.zdxh.shirodemo.entity.SysPerms;
    import cn.zdxh.shirodemo.entity.SysRole;
    import cn.zdxh.shirodemo.entity.SysUser;
    import com.baomidou.mybatisplus.mapper.BaseMapper;
    
    import java.util.List;
    
    public interface SysUserMapper extends BaseMapper<SysUser> {
        /**授权相关*/
        //通过用户ID查询该用户权限
        List<SysPerms> findAllPermsByUserId(Integer id);
        //通过用户ID查询该用户角色
        List<SysRole> findAllRolesByUserId(Integer id);
    
        /**认证相关*/
        //通过用户名查询该用户信息
        List<SysUser> findUserByUsername(String username);
    
    }

**在resources/mapper目录下**

**SysUserMapper.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="cn.zdxh.shirodemo.mapper.SysUserMapper">
        
        
        <select id="findAllPermsByUserId" parameterType="int" resultType="cn.zdxh.shirodemo.entity.SysPerms">
            SELECT p.id,p.perms FROM sys_user_role ur
            LEFT JOIN sys_role r
            ON ur.role_id = r.id
            LEFT JOIN sys_role_perms rp
            ON r.id = rp.role_id
            LEFT JOIN sys_perms p
            ON rp.perms_id = p.id
            WHERE ur.user_id= #{id}
        </select>
    
        
        <select id="findAllRolesByUserId" parameterType="int" resultType="cn.zdxh.shirodemo.entity.SysRole">
            SELECT r.id,r.create_user_id,r.role_name,r.role_remark,r.create_time
            FROM sys_user_role ur
            LEFT JOIN sys_role r
            ON ur.role_id = r.id
            WHERE ur.user_id = #{id}
        </select>
    
        
        <select id="findUserByUsername" parameterType="string" resultType="cn.zdxh.shirodemo.entity.SysUser">
            SELECT * FROM sys_user WHERE username = #{username}
        </select>
    
    </mapper>

**8、服务层**

**SysUserService**

package cn.zdxh.shirodemo.service;
    
    import cn.zdxh.shirodemo.entity.SysPerms;
    import cn.zdxh.shirodemo.entity.SysRole;
    import cn.zdxh.shirodemo.entity.SysUser;
    
    import java.util.List;
    
    public interface SysUserService {
        /**授权相关*/
        //通过用户ID查询该用户权限
        List<SysPerms> findAllPermsByUserId(Integer id);
        //通过用户ID查询该用户角色
        List<SysRole> findAllRolesByUserId(Integer id);
    
        /**认证相关*/
        //通过用户ID查询用户
        List<SysUser> findUserByUsername(String username);
    
        /**操作相关*/
        //查询所有用户
        List<SysUser> findAllUsers();
        //新增用户
        void addUser(SysUser sysUser);
    }

**SysUserServiceImpl**

package cn.zdxh.shirodemo.service.impl;
    
    import cn.zdxh.shirodemo.entity.SysPerms;
    import cn.zdxh.shirodemo.entity.SysRole;
    import cn.zdxh.shirodemo.entity.SysUser;
    import cn.zdxh.shirodemo.mapper.SysUserMapper;
    import cn.zdxh.shirodemo.service.SysUserService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import java.util.List;
    
    @Service
    public class SysUserServiceImpl implements SysUserService {
    
        @Autowired
        private SysUserMapper sysUserMapper;
    
        @Override
        public List<SysPerms> findAllPermsByUserId(Integer id) {
            return sysUserMapper.findAllPermsByUserId(id);
        }
    
        @Override
        public List<SysRole> findAllRolesByUserId(Integer id) {
            return sysUserMapper.findAllRolesByUserId(id);
        }
    
        @Override
        public List<SysUser> findUserByUsername(String username) {
            return sysUserMapper.findUserByUsername(username);
        }
    
        @Override
        public List<SysUser> findAllUsers() {
            return sysUserMapper.selectList(null);
        }
    
        @Override
        public void addUser(SysUser sysUser) {
            sysUserMapper.insert(sysUser);
        }
    }

## ##

### **9、自定义UserRealm，对接数据持久层（最重要的一步）** ###

**UserRealm**

package cn.zdxh.shirodemo.shiro;
    
    import cn.zdxh.shirodemo.entity.SysPerms;
    import cn.zdxh.shirodemo.entity.SysRole;
    import cn.zdxh.shirodemo.entity.SysUser;

        /**
         * 授权，需要授权才会调用该方法
         * @param principalCollection

         */
        @Override
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
            //参数是从认证方法参数一传过来的
            SysUser sysUser = (SysUser) principalCollection.getPrimaryPrincipal();
            //根据用户ID去数据库查询角色和权限,并封装角色名和权限名
            List<SysPerms> sysPerms = sysUserService.findAllPermsByUserId(sysUser.getId());
            List<SysRole> sysRoles = sysUserService.findAllRolesByUserId(sysUser.getId());
            Set<String> roles = new HashSet<>();

                    //分割出每个权限
                    String[] split = sysPerm.getPerms().split(",");
                    perms.addAll(Arrays.asList(split));
                }
            }
            //角色
            if (sysRoles != null && sysRoles.size() > 0){
                for (SysRole  sysRole : sysRoles){
                    roles.add(sysRole.getRoleName());
                }
            }
    
            SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();

         * 因为了我们使用到了MD5算法，所以得告知凭证匹配器利用该算法去匹配。
         * 真正匹配的方法：assertCredentialsMatcher
         */
        @Override
        public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {
            HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
            hashedCredentialsMatcher.setHashAlgorithmName("MD5");//指定加密算法，默认只加密一次，可以选择多次加密。这里的加密要对应新建用户时加密存储的密码
            super.setCredentialsMatcher(hashedCredentialsMatcher);
        }
    
    //    public static void main(String[] args) {
    //        try {
    //            String password = new Md5Hash("123456").toString();
    //            Md5Hash md5Hash = new Md5Hash("e10adc3949ba59abbe56e057f20f883e","f6281f61-ae3d-4b4c-8650-d73f4bf01208");
    //            System.out.println(password);//e780cbb524f6f54e2734b3114978820f
    //            System.out.println(md5Hash.toString());
    //        } catch (Exception e) {
    //            e.printStackTrace();
    //        }
    //    }
    
       
        
    }

doGetAuthorizationInfo：授权回调方法。去数据库查询该用户的角色和权限

doGetAuthenticationInfo：认证回调方法。去数据库查询该用户的相关信息

setCredentialsMatcher：需要加盐加密才需要重写该方法，否则不用

**加密策略：**

*  密码首先MD5加密一次
 *  随机生成一个salt值，与加密密码组合再MD5加密一次
 *  最后组成的加密密码和盐值存进数据库

## ##

### **10、Controller层** ###

**LoginController：用于登录和登出**

*  这里要注意下新建用户那里，密码的存储策略

        public Result<String> login(SysUser sysUser){
            //这里先将密码进行MD5,实际上这个步骤是前端做的
            sysUser.setPassword(new Md5Hash(sysUser.getPassword()).toString());
            //获取到主体

        }

            SecurityUtils.getSubject().logout();
            return Result.error("退出登录成功");
        }

        public Result<String> authfail(){
            return Result.error("没有操作权限");
        }
    
    }

**SysUserController：用于测试用户权限**

*  @RequiresPermissions() ：说明该api需要相应权限才能访问
 *  @RequiresRoles() : 说明该api需要相应的角色才能访问
 *  两者存在一种即可，方法一的粒度更小，应用更加广

### **12、统一异常管理** ###

**MyExceptionHandler：因为在没权限的时候，在拦截器那里跳转页面没有生效，所以只能在这里拦截没权限异常**

package cn.zdxh.shirodemo.exception;
    
    import cn.zdxh.shirodemo.utils.Result;
    import org.apache.shiro.authz.AuthorizationException;
    import org.springframework.web.bind.annotation.ControllerAdvice;
    import org.springframework.web.bind.annotation.ExceptionHandler;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    /**
     * 统一异常管理
     */
    @ControllerAdvice
    public class MyExceptionHandler {
    
        /**
         * 没有权限的异常
         * @param e
         * @return
         */
        @ResponseBody
        @ExceptionHandler(AuthorizationException.class)
        public Result<String> authorizationException(AuthorizationException e){
            return Result.error("没有操作权限");
        }
    
        /**
         * 其他的一些未知名异常
         * @param e
         * @return
         */
        @ResponseBody
        @ExceptionHandler(Exception.class)
        public Result<String> exception(Exception e){
            return Result.error(e.getMessage());
        }
    }

#    **三、测试结果** #

# **四、总结** #

*  Shiro权限管理系统是基于session实现的，这里暂未实现移动端的token认证方式，有兴趣的可以在这方面探究一下哦。
