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

Subject代表了当前用户的安全操作
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。
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。
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。
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。
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

Shiro两个重要的配置类：

1.UserRealm

  	 * @param principalCollection
  	 * @return
  	 */
  	@Override
  	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
  		System.out.println("执行授权逻辑");
  		/*获取当前登录的用户信息*/
  		Subject subject = SecurityUtils.getSubject();

  		}
  		return info;
  	}
  	/**

  	 */
  	@Override

  			return new SimpleAuthenticationInfo(testUser, testUser.getPassword(), this.getName());
  		}
  		//若用户名不存在则返回UnknownAccountException异常
  		return null;
  	}
  }

2.ShiroConfig

  package com.gt.shiro.config;
  import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
  import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
  import org.apache.shiro.spring.web.ShiroFilterFactoryBean;

  		 * 4.perms：对应权限才能访问
  		 * 5.role：对应角色才能访问
  		 */
  		//登录状态下才可以访问main页面，manage权限可访问manage页面，admin角色可访问admin页面
  		Map<String, String> filterMap = new LinkedHashMap<String, String>();
  		filterMap.put("/main", "authc");
  		filterMap.put("/manage", "perms[manage]");

  		shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
  		//未登录状态下访问将跳转至login页面
  		// 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
  		shiroFilterFactoryBean.setLoginUrl("/login");
  		// 登录成功后要跳转的链接
  		shiroFilterFactoryBean.setSuccessUrl("/");
  		//无授限状态下访问将请求unauthor
  		shiroFilterFactoryBean.setUnauthorizedUrl("/unAuth");
  		return shiroFilterFactoryBean;
  	}
  	@Bean(name = "securityManager")
  	public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm) {
  		DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
  		//DefaultWebSecurityManager需要关联一个Realm

  		resolver.setExceptionMappings(properties);
  		return resolver;
  	}
  }

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;
  import org.apache.shiro.authc.IncorrectCredentialsException;
  import org.apache.shiro.authc.UnknownAccountException;
  import org.apache.shiro.authc.UsernamePasswordToken;
  import org.apache.shiro.crypto.hash.SimpleHash;
  import org.apache.shiro.subject.Subject;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.stereotype.Controller;
  import org.springframework.ui.Model;
  import org.springframework.web.bind.annotation.*;
  @Controller
  public class indexController {
  	@Autowired
  	private TestUserServer testUserServer;
  	@GetMapping("/{url}")
  	public String redirect(@PathVariable("url") String url) {
  		return url;
  	}
  	@RequestMapping(value = {"/", "/index"}, method = RequestMethod.GET)
  	private String index() {
  		return "index";
  	}
  	@PostMapping("/login")
  	public String login(String username, String password, Model model) {
  		Subject subject = SecurityUtils.getSubject();
  		TestUser testUser = testUserServer.selectOneByName(username);
  		if (testUser != null) {
  			//根据salt值和用户输入的密码计算加密后的密码
  			String salt = testUser.getSalt();
  			password = new SimpleHash("md5", password, salt, 2).toString();
  			System.out.println(password);
  		}
  		UsernamePasswordToken token = new UsernamePasswordToken(username, password);
  		//UsernamePasswordToken token = new UsernamePasswordToken(username, testUser.getPassword());(不加密写法)
  		try {
  			//将用户名和密码通过token传给shiro进行认证
  			subject.login(token);
  			TestUser user = (TestUser) subject.getPrincipal();
  			subject.getSession().setAttribute("testUser", user);
  			return "index";
  		} catch (UnknownAccountException e) {
  			e.printStackTrace();
  			model.addAttribute("msg", "用户名不存在");
  			return "login";
  		} catch (IncorrectCredentialsException e) {
  			e.printStackTrace();
  			model.addAttribute("msg", "密码有误");
  			return "login";
  		}
  	}
  	@ResponseBody
  	@GetMapping("/unauthor")
  	public String unauthor() {
  		return "权限不足，无法访问";
  	}
  	@GetMapping("/logout")
  	public String logout() {
  		Subject subject = SecurityUtils.getSubject();
  		subject.logout();
  		return "login";
  	}

  			return "register";
  		} else if (password ** null || password.equals("")) {

  			return "register";
  		} else if (testUserServer.selectOneByName(username) != null) {
