Shiro

  • Apache Shiro 是一个java安全（权限）的框架
  • Shiro 可以非常容易的开发出足够好的应用，其不仅可以使用JavaSE环境，也可以用在javaEE环境
  • Shiro可以完成，认证，授权，加密管理，Web基础，缓存等
  • 下载地址https://shiro.apache.org

Shiro核心三大对象

Subject 用户
SecurityManager 管理所有用户
Realm 连接数据

Quickstart核心：

 //获取当前用户对象  Subject
Subject currentUser = SecurityUtils.getSubject();
//通过当前用户 获取获取session
Session session = currentUser.getSession();
//判断用户是否认证
if (!currentUser.isAuthenticated()) { 

// 获取当前用户的认证 存取信息
currentUser.getPrincipal() 
//判断用户是否有某个角色
if (currentUser.hasRole("schwartz")) {
//检测你是否有什么样的权限
if (currentUser.isPermitted("lightsaber:wield")) { 
//注销
currentUser.logout();

1.官方Quickstart案例

package com;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;

//import org.apache.shiro.ini.IniSecurityManagerFactory;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.realm.text.IniRealm;

import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
//import org.apache.shiro.lang.util.Factory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;


/**
 * Simple Quickstart application showing how to use Shiro's API.
 *
 * @since 0.9 RC2
 */
public class Quickstart {

    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);


    public static void main(String[] args) {

        //新方法   shiro更新问题,获取ini
        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
        securityManager.setRealm(iniRealm);

        SecurityUtils.setSecurityManager(securityManager);

        //获取当前的用户对象subject
        Subject currentUser = SecurityUtils.getSubject();

        //通过当前用户拿到session
        Session session = currentUser.getSession();
        session.setAttribute("someKey", "aValue");
        String value = (String) session.getAttribute("someKey");
        if (value.equals("aValue")) {
            log.info("Retrieved the correct value! [" + value + "]");
        }

        //判断当前的用户是否被认证
        if (!currentUser.isAuthenticated()) {
            //token：令牌，没有获取，随机
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
            token.setRememberMe(true);//设置记住我
            try {
                currentUser.login(token);//执行登录操作
            } catch (UnknownAccountException uae) {//用户名不存在
                log.info("There is no user with username of " + token.getPrincipal());
            } catch (IncorrectCredentialsException ice) {//密码不正确
                log.info("Password for account " + token.getPrincipal() + " was incorrect!");
            } catch (LockedAccountException lae) {//用户没锁定
                log.info("The account for username " + token.getPrincipal() + " is locked.  " +
                        "Please contact your administrator to unlock it.");
            }
            // ... catch more exceptions here (maybe custom ones specific to your application?
            catch (AuthenticationException ae) {
                //unexpected condition?  error?
            }
        }

        //获取用户信息
        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //获取角色
        if (currentUser.hasRole("schwartz")) {
            log.info("May the Schwartz be with you!");
        } else {
            log.info("Hello, mere mortal.");
        }

        //粗粒度
        //test a typed permission (not instance-level)
        if (currentUser.isPermitted("lightsaber:wield")) {
            log.info("You may use a lightsaber ring.  Use it wisely.");
        } else {
            log.info("Sorry, lightsaber rings are for schwartz masters only.");
        }

        //细粒度
        //a (very powerful) Instance Level permission:
        if (currentUser.isPermitted("winnebago:drive:eagle5")) {
            log.info("You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'.  " +
                    "Here are the keys - have fun!");
        } else {
            log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");
        }

        //注销
        //all done - log out!
        currentUser.logout();

        //结束
        System.exit(0);
    }
}

2.整合到SpringBoot，Shiro认证

导入jar包

<!--
Subject 用户
SecurityManager 管理所有用户
Realm 连接数据
-->
<!--         shiro整合spring的包-->
      <!-- Shiro整合Spring -->
      <dependency>
         <groupId>org.apache.shiro</groupId>
         <artifactId>shiro-spring</artifactId>
         <version>1.5.3</version>
      </dependency>
      <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-thymeleaf</artifactId>
      </dependency>
      <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-web</artifactId>
      </dependency>

编写一个controller并写出带有thymeleaf的html

package com.demo.controller;

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.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class MyController {
    @RequestMapping({"/","/idnex"})
    public String toIndex(Model model){
        model.addAttribute("msg","hello,Shiro");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }

    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }

    @RequestMapping("/toLogin")
    public String toLogin(){
        return "login";
    }

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        //获取当前用户
        Subject subject = SecurityUtils.getSubject();
        System.out.println(username+password+"1111");
        //获取用户登录数据
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);

        try{
            subject.login(token);//执行登录方法，如果没有异常就OK了
            return "index";
        }
        catch (UnknownAccountException e){//用户名不存在
            model.addAttribute("msg","用户名错误");
            return "login";
        }
        catch (IncorrectCredentialsException e){//密码不存在
            model.addAttribute("msg","密码不错误");
            return "login";
        }
    }
}

login.html:

配置shiroConfig

@Configuration
public class ShiroConfig {
    /**
     * @param defaultWebSecurityManager
     * @return
     */
    @Bean
    //ShiroFilterFactoryBean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);

        //添加shiro的内置过滤器
        /**
         * anon:无需认证就可以访问
         * authc：必须认证才能访问
         * user：必须拥有记住我功能才能用
         * perms：拥有对某个资源的全选才能访问
         * role：拥有某个角色才能访问
         */
        Map<String,String> filterChainDefinitionMap = new LinkedHashMap<>();

        filterChainDefinitionMap.put("/user/add","authc");
        filterChainDefinitionMap.put("/user/update","authc");

        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

        //设置登陆界面
        shiroFilterFactoryBean.setLoginUrl("/toLogin");

        return shiroFilterFactoryBean;
    }

    //DefaultWebSecurityManager
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //创建realm对象，自定义:===>第一步
    @Bean
    public UserRealm userRealm(){
        return  new UserRealm();
    }
}

实现UserRealm

package com.demo.config;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;

//自定义的UserRealm
public class UserRealm  extends AuthorizingRealm {

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        System.out.println("授权===>doGetAuthorizationInfo");
        return null;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("认证===>doGetAuthorizationInfo");

        //用户名，密码
        String name = "root";
        String password = "123456";

        UsernamePasswordToken userToken = (UsernamePasswordToken) token;
        if(!userToken.getUsername().equals(name)){
            return null; //UnknownAccountException
        }
        //密码认证，shiro做
        return  new SimpleAuthenticationInfo("",password,"");
    }
}

这个demo确实可以做到拦截功能但是并没有对用户功能进行分类，因此改进成下面的demo

3.数据库用户分类的整合,Shiro授权

创建一个数据库

DROP TABLE IF EXISTS `user`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!50503 SET character_set_client = utf8mb4 */;
CREATE TABLE `user` (
  `id` int NOT NULL,
  `name` varchar(30) DEFAULT NULL,
  `pwd` varchar(30) DEFAULT NULL,
  `perms` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3;
/*!40101 SET character_set_client = @saved_cs_client */;

--
-- Dumping data for table `user`
--

LOCK TABLES `user` WRITE;
/*!40000 ALTER TABLE `user` DISABLE KEYS */;
INSERT INTO `user` VALUES (1,'张三','123123','user:update'),(2,'李四','123456',NULL),(3,'王五','123456',NULL),(4,'赵六','123456',NULL),(6,'找牛','1221212',NULL),(7,'admin','123456','user:add');
/*!40000 ALTER TABLE `user` ENABLE KEYS */;
UNLOCK TABLES;

导入数据库的依赖以及druid链接池

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid-spring-boot-starter</artifactId>
  <version>1.1.10</version>
</dependency>

数据库配置

spring:
  datasource:
    username: root
    password: root1@12
    url: jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
    # 指定数据源
    type: com.alibaba.druid.pool.DruidDataSource

      #   数据源其他配置
    druid:
      #SpringBoot默认是不注入这些的，需要自己绑定
      #druid数据源专有配置
      initialSize: 5
      minIdle: 5
      maxActive: 20
      maxWait: 60000
      timeBetweenEvictionRunsMillis: 60000
      minEvictableIdleTimeMillis: 300000
      validationQuery: SELECT 1 FROM DUAL
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      poolPreparedStatements: true

      #配置监控统计拦截的filters，stat：监控统计、log4j：日志记录、wall：防御sql注入
      #如果允许报错，java.lang.ClassNotFoundException: org.apache.Log4j.Properity
      #则导入log4j 依赖就行
      filters: stat,wall,log4j
      maxPoolPreparedStatementPerConnectionSize: 20
      useGlobalDataSourceStat: true
      connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

mybatis配置

mybatis.type-aliases-package=com.pojo
mybatis.mapper-locations=classpath:mapper/*.xml

修改index界面

<!DOCTYPE html>

<html lang="en" xmlns:th="http://www.thymeleaf.org" xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">

<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h1>首页</h1>
    <p th:text="${msg}"></p>
    <div th:if="${session.loginUser==null}">
        <a th:href="@{/toLogin}">登录</a>
    </div>
    <hr>
    <div shiro:hasPermission="'user:add'">
        <a th:href="@{/user/add}">add</a>
    </div>

    <div shiro:hasPermission="'user:update'">
        <a th:href="@{/user/update}">update</a>
    </div>
</body>
</html>

写一个简单的未认证界面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>unauthorization</h1>
</body>
</html>

配置数据库实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private  int id;
    private String name;
    private String pwd;
    private String perms;
}

写一个mapper接口

@Repository
@Mapper
public interface UserMapper {
    public User queryUserByName(String name);
}

实现：

<?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">
<!--namespace=绑定一个对应对Dao接口-->
<mapper namespace="com.mapper.UserMapper">
    <select id="queryUserByName" parameterType="String" resultType="User">
        select * from mybatis.user where name=#{name}
    </select>
</mapper>

service接口

public interface UserService {
    public User queryUserByName(String name);

}

实现：

@Service
public class UserServiceImpl implements UserService{
    @Autowired
    UserMapper userMapper;
    @Override
    public User queryUserByName(String name) {
        return userMapper.queryUserByName(name);
    }
}

重写controller

package com.controller;

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.session.Session;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class MyController {
    @RequestMapping({"/","/idnex"})
    public String toIndex(Model model){
        model.addAttribute("msg","hello,Shiro");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }

    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }

    @RequestMapping("/toLogin")
    public String toLogin(){
        return "login";
    }

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        //获取当前用户
        Subject subject = SecurityUtils.getSubject();
        //获取用户登录数据
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);

        try{
            subject.login(token);//执行登录方法，如果没有异常就OK了

            return "index";
        }
        catch (UnknownAccountException e){//用户名不存在
            model.addAttribute("msg","用户名错误");
            return "login";
        }
        catch (IncorrectCredentialsException e){//密码不存在
            model.addAttribute("msg","密码不错误");
            return "login";
        }
    }
    @RequestMapping("/noauth")
    public String unantuorized(){
        return  "unauthorization";
    }
}

重写shiroConfig

package com.config;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;

@Configuration
public class ShiroConfig {
    @Bean
    //ShiroFilterFactoryBean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);

        //添加shiro的内置过滤器
        /**
         *
         * anon:无需认证就可以访问
         * authc：必须认证才能访问
         * user：必须拥有记住我功能才能用
         * perms：拥有对某个资源的全选才能访问
         * role：拥有某个角色才能访问
         */
        Map<String,String> filterChainDefinitionMap = new LinkedHashMap<>();

        //授权，正常情况下，没有授权会跳转到为授权页面
        filterChainDefinitionMap.put("/user/add","perms[user:add]");
        filterChainDefinitionMap.put("/user/update","perms[user:update]");

        //拦截
        filterChainDefinitionMap.put("/user/*","authc");

        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

        //设置登陆界面
        shiroFilterFactoryBean.setLoginUrl("/toLogin");

        //设置为授权的页面
        shiroFilterFactoryBean.setUnauthorizedUrl("/noauth");

        return shiroFilterFactoryBean;
    }

    //DefaultWebSecurityManager
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //创建realm对象，自定义:===>第一步
    @Bean
    public UserRealm userRealm(){
        return  new UserRealm();
    }

    @Bean
    //整合shiroDialect；用来整合shiro thymeleof
    public ShiroDialect getShiroDialect(){
        return  new ShiroDialect();
    }
}

重新实现UserRealm

package com.config;

import com.pojo.User;
import com.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;

//自定义的UserRealm
public class UserRealm  extends AuthorizingRealm {

    @Autowired
    UserService userService;
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        System.out.println("授权===>doGetAuthorizationInfo");
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//        info.addStringPermission("user:add");

        //拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
        //拿到User对象
        User currentUser = (User) subject.getPrincipal();
        //设置当前用户的权限
        info.addStringPermission(currentUser.getPerms());
        return info;
    }
    //认证
    @Override

        System.out.println("认证===>doGetAuthorizationInfo");


        UsernamePasswordToken userToken = (UsernamePasswordToken) token;

        //连接数据库
        User user = userService.queryUserByName(userToken.getUsername());
        if (user==null){
            //UnknownAccountException
            return null;
        }
        Subject current = SecurityUtils.getSubject();
        Session session = current.getSession();
        session.setAttribute("loginUser",user);
        //可以加密，MD5，MD5盐值加密（MD5值后面加上一些用户的属性）
        //密码认证，shiro做
        return  new SimpleAuthenticationInfo(user,user.getPwd(),"");
    }
}
