Springboot整合shiro，带你学会shiro，入门级别教程，由浅入深，完整代码案例，各位项目想加这个模块的人也可以看这个，又或者不会mybatis-plus的也可以看这个

如果你对shiro有问题的话，请看这篇文章：Springboot+shiro,完整教程，带你学会shiro-CSDN博客

第一步，先准备数据库：

数据库需要准备三个表，一个user表，一个role表，一个permission表。

user表：

CREATE TABLE `user` (
  `id` int NOT NULL,
  `username` varchar(100) DEFAULT NULL,
  `password` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

role表：

CREATE TABLE `role` (
  `id` int NOT NULL,
  `name` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

permission表:

CREATE TABLE `permission` (
  `id` int NOT NULL,
  `name` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

然后插入数据：

第一个是user表，第二个是permission表，第三个是role表。大家自己建就是了。

第二步就是创建springboot项目，并操作数据库。

application文件：

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/tianfan?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC

配置实体类：

user类：

package org.tianfan.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import java.io.Serializable;
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class User implements Serializable {
    private Long id;
    private String username;
    private String password;
}

Role类：

package org.tianfan.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import java.io.Serializable;
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Role implements Serializable {
    private Long id;
    private String name;
    // getter and setter
}

permission类：

package org.tianfan.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.ToString;
import java.io.Serializable;
@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString
public class Permission implements Serializable {
    private Long id;
    private String name;
    // getter and setter
}

准备mapper

PermissionMapper

package org.tianfan.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.tianfan.pojo.Permission;
public interface PermissionMapper extends BaseMapper<Permission> {
}

RoleMapper

package org.tianfan.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.tianfan.pojo.Role;
public interface RoleMapper extends BaseMapper<Role> {
}

UserMapper

package org.tianfan.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;
import org.tianfan.pojo.User;
@Mapper
public interface UserMapper extends BaseMapper<User> {
}

准备service

UserService：

package org.tianfan.service;
import org.apache.ibatis.annotations.Mapper;
import org.tianfan.pojo.Permission;
import org.tianfan.pojo.Role;
import org.tianfan.pojo.User;
import java.util.List;
public interface UserService {
    User findByUsername(String username);
    List<Role> findRolesByUserId(Long userId);
    List<Permission> findPermissionsByRoleId(Long roleId);
}

准备serviceImpl

UserServiceImpl

package org.tianfan.service.impl;
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.tianfan.mapper.PermissionMapper;
import org.tianfan.mapper.RoleMapper;
import org.tianfan.mapper.UserMapper;
import org.tianfan.pojo.Permission;
import org.tianfan.pojo.Role;
import org.tianfan.pojo.User;
import org.tianfan.service.UserService;
import java.util.ArrayList;
import java.util.List;
@Service
public class UserServiceImpl implements UserService {
    @Autowired
    UserMapper userMapper;
    @Autowired
    RoleMapper roleMapper;
    @Autowired
    PermissionMapper permissionMapper;
    @Override
    public User findByUsername(String username) {
        LambdaQueryWrapper<User> lambdaQueryWrapper=new LambdaQueryWrapper();
        lambdaQueryWrapper.eq(User::getUsername,username);
        User user = userMapper.selectOne(lambdaQueryWrapper);
        System.out.println(user);
        return user;
    }
    @Override
    public List<Role> findRolesByUserId(Long userId) {
        LambdaQueryWrapper lambdaQueryWrapper=new LambdaQueryWrapper();
        lambdaQueryWrapper.eq("id",userId);
        Role role = roleMapper.selectOne(lambdaQueryWrapper);
        List<Role> list=new ArrayList<>();
        list.add(role);
        return list;
    }
    @Override
    public List<Permission> findPermissionsByRoleId(Long roleId) {
        LambdaQueryWrapper lambdaQueryWrapper=new LambdaQueryWrapper();
        lambdaQueryWrapper.eq("id",roleId);
        Permission permission = permissionMapper.selectOne(lambdaQueryWrapper);
        List<Permission> list=new ArrayList<>();
        list.add(permission);
        return list;
    }
}

现在为止，开始配置shiro

配置一下ShiroConfig，配置那些比如说shiro要过滤的请求，securityManager（管理shiro对象的类）拿到主体的关键类，MyShiroRealm认证规格类，LifecycleBeanPostProcessor，用于在Spring容器中管理Shiro的生命周期。

package org.tianfan.config;
import org.apache.shiro.mgt.SessionsSecurityManager;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.apache.shiro.mgt.SecurityManager;
import java.util.LinkedHashMap;
import java.util.Map;
@Configuration
public class ShiroConfig {
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        filterChainDefinitionMap.put("/login", "anon");
        filterChainDefinitionMap.put("/login.html", "anon");
        filterChainDefinitionMap.put("/**", "authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }
    @Bean
    public SessionsSecurityManager securityManager(MyShiroRealm userRealm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //配置realm
        securityManager.setRealm(userRealm);
        return securityManager;
    }
    @Bean
    public MyShiroRealm myShiroRealm() {
        MyShiroRealm myShiroRealm = new MyShiroRealm();
        return myShiroRealm;
    }
    @Bean
    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }
    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
        defaultAdvisorAutoProxyCreator.setProxyTargetClass(true);
        return defaultAdvisorAutoProxyCreator;
    }
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }
}

MyShiroRealm认证规格类：

package org.tianfan.config;
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.springframework.beans.factory.annotation.Autowired;
import org.tianfan.service.UserService;
import org.tianfan.pojo.Permission;
import org.tianfan.pojo.Role;
import org.tianfan.pojo.User;
import org.tianfan.service.impl.UserServiceImpl;
import java.util.List;
public class MyShiroRealm extends AuthorizingRealm {
    @Autowired
    private UserServiceImpl userService;
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        User user = (User) principalCollection.getPrimaryPrincipal();
        List<Role> roles = userService.findRolesByUserId(user.getId());
        for (Role role : roles) {
            authorizationInfo.addRole(role.getName());
            List<Permission> permissions = userService.findPermissionsByRoleId(role.getId());
            for (Permission permission : permissions) {
                authorizationInfo.addStringPermission(permission.getName());
            }
        }
        return authorizationInfo;
    }
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        System.out.println(token.getUsername());
        User user = userService.findByUsername(token.getUsername());
        if (user == null) {
            throw new UnknownAccountException();
        }
        return new SimpleAuthenticationInfo(user, user.getPassword(), getName());
    }
}

现在就可以测试了，Contoller类：

package org.tianfan.contoller;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import org.tianfan.pojo.User;
import org.tianfan.service.UserService;
@RestController
public class UserController {
    @Autowired
    private UserService userService;
    @PostMapping("/login")
    public String login( String username,  String password) {
        System.out.println(username+password);
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        try {
            subject.login(token);
            return "登录成功";
        } catch (AuthenticationException e) {
            return "用户名或密码错误";
        }
    }
    @GetMapping("/user")
    public User getUser() {
        Subject subject = SecurityUtils.getSubject();
        return (User) subject.getPrincipal();
    }
    @GetMapping("/admin")
    public String admin() {
        return "admin";
    }
}

主类：

package org.tianfan;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class);
    }
}

运行启动结果图：

输入正确的密码：

之后就可以直接访问

如果没有登录正确的账号信息的话，就不可以访问这个，并且会直接跳转到login.jsp
