Springboot+Shiro+Mybatis+mysql实现权限安全认证

2024-07-05 22:01 由 二价亚铁 发表于 #后端开发

Shiro是Apache 的一个强大且易用的Java安全框架,执行身份验证、授权、密码学和会话管理。Shiro 主要分为两个部分就是认证和授权两部分

一、介绍

  1. Subject代表了当前用户的安全操作

  2. 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。

  3. Authenticator即认证器，对用户身份进行认证，Authenticator是一个接口，shiro提供ModularRealmAuthenticator实现类，通过ModularRealmAuthenticator基本上可以满足大多数需求，也可以自定义认证器。

  4. Authorizer即授权器，用户通过认证器认证通过，在访问功能时需要通过授权器判断用户是否有此功能的操作权限。

  5. 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。

  6. sessionManager即会话管理，shiro框架定义了一套会话管理，它不依赖web容器的session，所以shiro可以使用在非web应用上。

Shiro相关类介绍

  • （1）Authentication 认证 —— 用户登录

  • （2）Authorization 授权 —- 用户具有哪些权限

  • （3）Cryptography 安全数据加密

  • （4）Session Management 会话管理

  • （5）Web Integration web系统集成

  • （6）Interations 集成其它应用，spring、缓存框架

二、依赖引入

完整的pom文件如下：

三、配置文件

application.yml配置文件：

spring.thymeleaf.cache=false
# 用非严格的 HTML
spring.thymeleaf.mode=HTML
spring.thymeleaf.encoding=utf-8

  			info.addStringPermission(testUser.getPerms());
  		}
  		return info;
  	}
  	/**

  }

四、数据连接和业务逻辑

  • 1.实体类

      package com.gt.shiro.entity;
  import lombok.Data;
  import lombok.experimental.Accessors;
  import java.io.Serializable;
  import java.util.Date;
  @Data
  @Accessors(chain = true)
  public class TestUser implements Serializable {
  	private Integer id;
  	private String username;
  	private String password;
  	/*权限*/
  	private String perms;
  	/*角色*/
  	private String role;
  	/*加盐密码*/
  	private String salt;
  }

  • 2.Dao和Mapper

      package com.gt.shiro.dao;
  import com.gt.shiro.entity.TestUser;
  import org.apache.ibatis.annotations.Mapper;
  import java.util.List;
  @Mapper
  public interface TestUserMapper {
  	List<TestUser> findAll();
  	TestUser selectOne(Integer id);
  	TestUser selectOneByName(String username);
  	void insert(TestUser testUser);
  	void update(TestUser testUser);
  	void delete(Integer id);
  }

<?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.gt.shiro.dao.TestUserMapper">
	<select id="findAll"  resultType="TestUser">
	   select * from test_user
	</select>
	<select id="selectOne" resultType="TestUser">
	   select * from test_user where id=#{id}
	</select>
	<select id="selectOneByName" resultType="TestUser">
	   select * from test_user where username=#{username}
	</select>
	<insert id="insert">
		insert into test_user (id,username,password,perms,role,salt) value (#{id},#{username},#{password},#{perms},#{role},#{salt})
	</insert>
	<update id="update">
		update test_user set username = #{username},password=#{password},perms=#{perms},role=#{role},salt=#{salt} where id = #{id}
	</update>
	<delete id="delete">
		delete from test_user where id = #{id}
	</delete>
</mapper>

  • 3.业务层及其实现

      package com.gt.shiro.server;
  import com.gt.shiro.entity.TestUser;
  import org.springframework.stereotype.Service;
  import java.util.List;
  @Service
  public interface TestUserServer {
  	/*查询所有*/
  	List<TestUser> selectAll();
  	/*查询一个用户*/
  	TestUser selectByOne(Integer id);
  	/*通过名字查询一个用户*/
  	TestUser selectOneByName(String name);
  	/*增加一个用户*/
  	void insert(TestUser testUser);
  	/*删除一个用户*/
  	void delete(Integer id);
  	/*更新一个用户*/
  	void update(TestUser testUser);
  }

package com.gt.shiro.server.serverImpl;
import com.gt.shiro.dao.TestUserMapper;
import com.gt.shiro.entity.TestUser;
import org.apache.shiro.crypto.SecureRandomNumberGenerator;
import org.apache.shiro.crypto.hash.SimpleHash;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.sunyue.shiro.server.TestUserServer;
import java.util.List;
@Service
public class TestUserServerImpl implements TestUserServer {
	@Autowired
	private TestUserMapper testUserMapper;
	@Override
	public List<TestUser> selectAll() {
		return testUserMapper.findAll();
	}
	@Override
	public TestUser selectByOne(Integer id) {
		return testUserMapper.selectOne(id);
	}
	@Override
	public TestUser selectOneByName(String name) {
		return testUserMapper.selectOneByName(name);
	}
	@Override
	public void insert(TestUser testUser) {
		//加密写法
		String salt = new SecureRandomNumberGenerator().nextBytes().toString();
		String password= new SimpleHash("md5",testUser.getPassword(),salt,2).toString();
		testUser.setPassword(password);
		testUser.setSalt(salt);
		testUserMapper.insert(testUser);
	}
	@Override
	public void delete(Integer id) {
		testUserMapper.delete(id);
	}
	@Override
	public void update(TestUser testUser) {
		testUserMapper.update(testUser);
	}
}

  • 4.控制层

      package com.gt.shiro.controller;
  import com.gt.shiro.entity.TestUser;
  import com.gt.shiro.server.TestUserServer;
  import org.apache.shiro.SecurityUtils;
