这篇文章主要讲解了"Java安全框架Shiro怎么使用"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"Java安全框架Shiro怎么使用"吧！

Shiro简介

Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理
三个核心组件：Subject, SecurityManager 和 Realms
Subject代表了当前用户的安全操作
SecurityManager管理所有用户的安全操作，是Shiro框架的核心，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。
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。
Realm实质上是一个安全相关的DAO：它封装了数据源的连接细节，并在需要时将相关数据提供给Shiro。当配置Shiro时，你必须至少指定一个Realm，用于认证和（或）授权。配置多个Realm是可以的，但是至少需要一个。

Shiro快速入门

导入依赖

                    org.apache.shiro            shiro-core            1.7.1                                            org.slf4j            jcl-over-slf4j            2.0.0-alpha1                            org.slf4j            slf4j-log4j12            2.0.0-alpha1                            log4j            log4j            1.2.17

配置log4j.properties

启动测试

SpringBoot-Shiro整合（最后会附上完整代码）

前期工作

导入shiro-spring整合包依赖

    org.apache.shiro    shiro-spring    1.7.1

编写shiro的配置类ShiroConfig.java

package com.example.config;import org.apache.shiro.spring.web.ShiroFilterFactoryBean;import org.apache.shiro.web.mgt.DefaultWebSecurityManager;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import java.util.LinkedHashMap;import java.util.Map;@Configurationpublic class ShiroConfig {    //3. ShiroFilterFactoryBean    @Bean    public ShiroFilterFactoryBean getshiroFilterFactoryBean(@Qualifier("SecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){        ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();        //设置安全管理器        factoryBean.setSecurityManager(defaultWebSecurityManager);        return factoryBean;    }    //2.创建DefaultWebSecurityManager    @Bean(name = "SecurityManager")    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){        DefaultWebSecurityManager SecurityManager=new DefaultWebSecurityManager();        //3.关联Realm        SecurityManager.setRealm(userRealm);        return SecurityManager;    }    //1.创建Realm对象    @Bean(name = "userRealm")    public UserRealm userRealm(){        return new UserRealm();    }}

编写UserRealm.java

package com.example.config;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.AuthenticationInfo;import org.apache.shiro.authc.AuthenticationToken;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.subject.PrincipalCollection;public class UserRealm extends AuthorizingRealm {    @Override    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {        System.out.println("授权");        return null;    }    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {        System.out.println("认证");        return null;    }}

编写controller测试环境是否搭建好

package com.example.controller;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class MyController {    @RequestMapping({"/","/index"})    public String index(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";    }}

实现登录拦截

在ShiroConfig.java文件中添加拦截

Map filterMap = new LinkedHashMap<>();        //对/user/*下的文件只有拥有authc权限的才能访问        filterMap.put("/user/*","authc");        //将Map存放到ShiroFilterFactoryBean中        factoryBean.setFilterChainDefinitionMap(filterMap);

这样，代码跑起来，你点击add或者update就会出现404错误，这时候，我们再继续添加，让它跳转到我们自定义的登录页

添加登录拦截到登录页

        //需进行权限认证时跳转到toLogin        factoryBean.setLoginUrl("/toLogin");        //权限认证失败时跳转到unauthorized        factoryBean.setUnauthorizedUrl("/unauthorized");

        登录    用户名:
    密码:

视图跳转添加一个login页面跳转

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

上面，我们已经成功拦截了，现在我们来实现用户认证

首先，我们需要一个登录页面

其次，去controller编写跳转到登录页面

    @RequestMapping("/login")    public String login(String username,String password,Model model){        //获得当前的用户        Subject subject = SecurityUtils.getSubject();        //封装用户数据        UsernamePasswordToken taken = new UsernamePasswordToken(username,password);        try{//执行登陆操作，没有发生异常就说明登陆成功            subject.login(taken);            return "index";        }catch (UnknownAccountException e){            model.addAttribute("msg","用户名错误");            return "login";        }catch (IncorrectCredentialsException e){            model.addAttribute("msg","密码错误");            return "login";        }    }

最后去UserRealm.java配置认证

   //认证    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {        System.out.println("认证");        String name = "root";        String password = "123456";        UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;        if (!userToken.getUsername().equals(name)){            return null;//抛出异常  用户名错误那个异常        }        //密码认证，shiro自己做        return new SimpleAuthenticationInfo("",password,"");    }

运行测试，成功！！！

UserRealm.java

package com.example.config;import org.apache.shiro.authc.*;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.subject.PrincipalCollection;public class UserRealm extends AuthorizingRealm {    //授权    @Override    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {        System.out.println("授权");        return null;    }    //认证    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {        System.out.println("认证");        String name = "root";        String password = "123456";        UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;        if (!userToken.getUsername().equals(name)){            return null;//抛出异常  用户名错误那个异常        }        //密码认证，shiro自己做        return new SimpleAuthenticationInfo("",password,"");    }}

但是，我们在用户认证这里，真实情况是从数据库中取的，所以，我们接下来去实现一下从数据库中取出数据来实现用户认证

Shiro整合mybatis

前期工作

在前面导入的依赖中，继续添加以下依赖

                            mysql            mysql-connector-java                                    log4j            log4j            1.2.17                                    com.alibaba            druid            1.2.5                                    org.mybatis.spring.boot            mybatis-spring-boot-starter            2.1.4                                    org.projectlombok            lombok

导入了mybatis和Druid，就去application.properties配置一下和Druid
Druid

spring:  datasource:    username: root    password: 123456    url: jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8    driver-class-name: com.mysql.cj.jdbc.Driver    type: com.alibaba.druid.pool.DruidDataSource # 自定义数据源    #Spring Boot 默认是不注入这些属性值的，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    #如果允许时报错  java.lang.ClassNotFoundException: org.apache.log4j.Priority    #则导入 log4j 依赖即可，Maven 地址：https://mvnrepository.com/artifact/log4j/log4j    filters: stat,wall,log4j    maxPoolPreparedStatementPerConnectionSize: 20    useGlobalDataSourceStat: true    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

mybatis

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

连接数据库
编写实体类

package com.example.pojo;import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;@Data@AllArgsConstructor@NoArgsConstructorpublic class User {        private Integer id;        private String name;        private String pwd;}

编写mapper

package com.example.mapper;import com.example.pojo.User;import org.apache.ibatis.annotations.Mapper;import org.springframework.stereotype.Repository;@Repository@Mapperpublic interface UserMapper {    public User getUserByName(String name);}

编写mapper.xml

编写service

package com.example.service;import com.example.pojo.User;public interface UserService {    public User getUserByName(String name);}

package com.example.service;import com.example.mapper.UserMapper;import com.example.pojo.User;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;@Servicepublic class UserServiceImpl implements UserService{    @Autowired    UserMapper userMapper;    @Override    public User getUserByName(String name) {        return userMapper.getUserByName(name);    }}

使用数据库中的数据

修改UserRealm.java即可

package com.example.config;import com.example.pojo.User;import com.example.service.UserService;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.springframework.beans.factory.annotation.Autowired;public class UserRealm extends AuthorizingRealm {    @Autowired    UserService userService;    //授权    @Override    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {        System.out.println("授权");        return null;    }    //认证    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {        System.out.println("认证");        UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;        //连接真实的数据库        User user = userService.getUserByName(userToken.getUsername());        if (user==null){            return null;//抛出异常  用户名错误那个异常        }        //密码认证，shiro自己做        return new SimpleAuthenticationInfo("",user.getPwd(),"");    }}

认证搞完了，我们再来看看授权

在ShiroConfig.java文件加入授权，加入这行代码： filterMap.put("/user/add","perms[user:add]");//只有拥有user:add权限的人才能访问add，注意授权的位置在认证前面，不然授权会认证不了；

运行测试：add页面无法访问

授权同理：filterMap.put("/user/update","perms[user:update]");//只有拥有user:update权限的人才能访问update

自定义一个未授权跳转页面

在ShiroConfig.java文件设置未授权时跳转到unauthorized页面，加入这行代码：
factoryBean.setUnauthorizedUrl("/unauthorized"); 2. 去Mycontroller写跳转未授权页面

    @RequestMapping("/unauthorized")    @ResponseBody//懒得写界面，返回一个字符串    public String unauthorized(){        return "没有授权，无法访问";    }

在数据库中添加一个属性perms，相应的实体类也要修改

修改UserRealm.java

package com.example.config;import com.example.pojo.User;import com.example.service.UserService;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;public class UserRealm extends AuthorizingRealm {    @Autowired    UserService userService;    //授权    @Override    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {        System.out.println("授权");        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();        //没有使用数据库，直接自己设置的用户权限，给每个人都设置了，现实中要从数据库中取        //info.addStringPermission("user:add");        //从数据库中得到权限信息        //获得当前登录的对象        Subject subject = SecurityUtils.getSubject();        //拿到User对象，通过getPrincipal()获得        User currentUser = (User) subject.getPrincipal();        //设置当前用户的权限        info.addStringPermission(currentUser.getPerms());        return info;    }    //认证    @Override    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {        System.out.println("认证");        UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;        //连接真实的数据库        User user = userService.getUserByName(userToken.getUsername());        if (user==null){            return null;//抛出异常  用户名错误那个异常        }        //密码认证，shiro自己做        return new SimpleAuthenticationInfo(user,user.getPwd(),"");    }}

有了授权后，就又出现了一个问题，我们是不是要让用户没有权限的东西，就看不见呢？这时候，就出现了Shiro-thymeleaf整合

Shiro-thymeleaf整合

导入整合的依赖

   com.github.theborakompanioni    thymeleaf-extras-shiro    2.0.0

在ShiroConfig整合ShiroDialect

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

修改index页面

首页

add

update

判断是否有用户登录

   //这个是整合shiro和thymeleaf用到的，让登录按钮消失的判断        Subject subject = SecurityUtils.getSubject();        Session session = subject.getSession();        session.setAttribute("loginUser", user);
