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

完整的pom文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.1</version><relativePath></relativePath> <!-- lookup parent from repository --></parent><groupId>com.gt.shiro</groupId><artifactId>com.sunyue.shiro</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><properties><java.version>1.8</java.version><druid.verzion>1.1.10</druid.verzion><pagehelper.version>1.2.10</pagehelper.version><mybatis.version>2.1.4</mybatis.version><thymeleaf-layout-dialect.version>2.0.4</thymeleaf-layout-dialect.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><!-- 排除默认的tomcat --><exclusions><exclusion><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId></exclusion></exclusions></dependency><!-- 重新依赖Jetty的starter --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jetty</artifactId></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-thymeleaf</artifactId></dependency><dependency><groupId>com.github.theborakompanioni</groupId><artifactId>thymeleaf-extras-shiro</artifactId><version>2.0.0</version></dependency><!--shiro整合spring--><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-spring</artifactId><version>1.4.0</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>${druid.verzion}</version></dependency><!-- https://mvnrepository.com/artifact/com.github.pagehelper/pagehelper-spring-boot-starter --><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper-spring-boot-starter</artifactId><version>${pagehelper.version}</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><!-- spring boot maven插件 --><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><mainClass>com.gt.shiro.SpringShiroApplication</mainClass></configuration></plugin></plugins></build>

三、配置文件

application.yml配置文件：
# 开发时关闭缓存,不然没法看到实时页面
spring.thymeleaf.cache=false
# 用非严格的 HTML
spring.thymeleaf.mode=HTML
spring.thymeleaf.encoding=utf-8
spring.thymeleaf.servlet.content-type=text/html
spring.datasource.druid.url=jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
spring.datasource.druid.username=root
spring.datasource.druid.password=admin
spring.datasource.druid.initial-size=1
spring.datasource.druid.min-idle=1
spring.datasource.druid.max-active=20

spring.redis.password=sunyue
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.jedis.pool.max-idle=200
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.jedis.pool.max-wait=-1
# 连接池中的最小空闲连接
spring.redis.jedis.pool.min-idle=0
# 连接超时时间（毫秒）
spring.redis.timeout=1000

Shiro两个重要的配置类：

1.UserRealm

  package com.gt.shiro.config;import com.gt.shiro.entity.TestUser;import com.gt.shiro.server.TestUserServer;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;import java.util.ArrayList;import java.util.HashSet;import java.util.List;import java.util.Set;public class UserRealm extends AuthorizingRealm {@Autowiredprivate TestUserServer testUserServer;/*** 执行授权逻辑** @param principalCollection* @return*/@Overrideprotected 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();TestUser testUser = (TestUser) subject.getPrincipal();//设置角色,多个角色/*Set<String> rolesSet = new HashSet<>();rolesSet.add(testUser.getRole());*///SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(rolesSet);//给资源进行授权SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();/*可以在以下list加入多个权限*//*List<String> roles = new ArrayList<>();roles.add(testUser.getPerms());info.addRoles(roles);*///设置权限info.addRole(testUser.getRole());//需要判断权限是否为空值（null是没有地址，""是有地址但是里面的内容是空的）if (testUser.getPerms() != null && !testUser.getPerms().equals("")) {info.addStringPermission(testUser.getPerms());}return info;}/*** 执行认证逻辑** @param authenticationToken* @return* @throws AuthenticationException*/@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {System.out.println("执行认证逻辑");/*获取令牌*/UsernamePasswordToken passwordToken = (UsernamePasswordToken) authenticationToken;//取出用户名并且判断用户名是否和数据库一致TestUser testUser = testUserServer.selectOneByName(passwordToken.getUsername());if (testUser != null) {//进行认证，将正确数据给shiro处理//密码不用自己比对，AuthenticationInfo认证信息对象，一个接口，new他的实现类对象SimpleAuthenticationInfo/*    第一个参数随便放，可以放user对象，程序可在任意位置获取 放入的对象* 第二个参数必须放密码，* 第三个参数放 当前realm的名字，因为可能有多个realm*///若密码不正确则返回IncorrectCredentialsException异常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;import org.apache.shiro.mgt.SecurityManager;import org.apache.shiro.web.mgt.DefaultWebSecurityManager;import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.handler.SimpleMappingExceptionResolver;import java.util.LinkedHashMap;import java.util.Map;import java.util.Properties;@Configurationpublic class ShiroConfig {@Beanpublic ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager) {ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();//设置安全管理器shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);//添加一些Shiro的内置过滤器/*** Shiro 的内置过滤器可以实现权限的相关拦截* 常用过滤器* 1.anon:无需认证* 2.authc:必须认证才能访问* 3.user：如果使用rememberme功能可以访问* 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]");filterMap.put("/admin", "roles[admin]");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unauthorshiroFilterFactoryBean.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RealmdefaultWebSecurityManager.setRealm(userRealm);return defaultWebSecurityManager;}/*** 创建realm*/@Bean(name = "userRealm")public UserRealm getRealm() {return new UserRealm();}@Beanpublic ShiroDialect shiroDialect() {return new ShiroDialect();}/*** 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions)* 配置以下两个bean(DefaultAdvisorAutoProxyCreator和AuthorizationAttributeSourceAdvisor)即可实现此功能** @return*/@Beanpublic DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();advisorAutoProxyCreator.setProxyTargetClass(true);return advisorAutoProxyCreator;}/*** 开启 shiro 的@RequiresPermissions注解** @param securityManager* @return*/@Beanpublic AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);return authorizationAttributeSourceAdvisor;}/*** shiro出现权限异常可通过此异常实现制定页面的跳转(或接口跳转)** @return*/@Beanpublic SimpleMappingExceptionResolver simpleMappingExceptionResolver() {SimpleMappingExceptionResolver resolver = new SimpleMappingExceptionResolver();Properties properties = new Properties();/*未授权处理页*/properties.setProperty("org.apache.shiro.authz.UnauthorizedException", "/error.html");/*身份没有验证*/properties.setProperty("org.apache.shiro.authz.UnauthenticatedException", "/error.html");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;@Mapperpublic 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;@Servicepublic 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 {@Autowiredprivate TestUserMapper testUserMapper;@Overridepublic List<TestUser> selectAll() {return testUserMapper.findAll();}@Overridepublic TestUser selectByOne(Integer id) {return testUserMapper.selectOne(id);}@Overridepublic TestUser selectOneByName(String name) {return testUserMapper.selectOneByName(name);}@Overridepublic 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);}@Overridepublic void delete(Integer id) {testUserMapper.delete(id);}@Overridepublic 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.*;@Controllerpublic class indexController {@Autowiredprivate 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";}@PostMapping("/register")public String register(TestUser testUser, Model model) {String username = testUser.getUsername();String password = testUser.getPassword();if (username ** null || username.equals("")) {model.addAttribute("msg", "用户名不能为空");return "register";} else if (password ** null || password.equals("")) {model.addAttribute("msg", "密码不能为空");return "register";} else if (testUserServer.selectOneByName(username) != null) {model.addAttribute("msg", "用户名已被占用");return "register";} else {testUserServer.insert(testUser);return "login";}}}
