SpringBoot集成Shiro安全框架

SpringBoot集成Shiro安全框架

    • 3.完成的效果

1.shiro的定义

1.shiro的作用
认证、授权、加密、会话管理、Web集成、缓存

2.shiro的名词
在这里插入图片描述

Authentication:身份认证/登录,验证用户是不是拥有相应的身份
Authorization:授权,即权限 管理,验证某个人已经登录的人是否拥有某些权限
Session Management:会话管理,即用户登录后就是一次会话,在没有退出之前所有的信息都是在会话中。。
Cryptography:加密,保护数据的安全性,密码加密
Web Support:Web支持,可以非常容易的集成到web环境
Caching:缓存,比如用户登录之后,他的用户信息,权限不必每次去查
Concurrency:shiro支持多线程应用兵法验证,即如果在一个线程中开启另外一个线程,权限会自动传递过去
Testing:提供测试支持
Run AS:允许一个用户假装另一个用户(如果他们允许)的身份进行访问
Remember Me:记住我,这是一个常见的功能,即一次登录后,下次再来的话就不用登录了
记住一点,Shiro不会去维护用户、维护权限:这些需要我们自己去设计/提供,然后通过相应的接口注入给Shiro即可!

3.shiro的架构
在这里插入图片描述
Subject,Subject其实代表的就是当前正在执行操作的用户,只不过因为“User”一般指代人,但是一个“Subject”可以是人,也可以是任何的第三方系统,服务账号等任何其他正在和当前系统交互的第三方软件系统。
所有的Subject实例都被绑定到一个SecurityManager,如果你和一个Subject交互,所有的交互动作都会被转换成Subject与SecurityManager的交互。

SecurityManager。SecurityManager是Shiro的核心,他主要用于协调Shiro内部各种安全组件,不过我们一般不用太关心SecurityManager,对于应用程序开发者来说,主要还是使用Subject的API来处理各种安全验证逻辑。

Realm,这是用于连接Shiro和客户系统的用户数据的桥梁。一旦Shiro真正需要访问各种安全相关的数据(比如使用用户账户来做用户身份验证以及权限验证)时,他总是通过调用系统配置的各种Realm来读取数据。

2.SpringBoot集成shiro的步骤

1.添加maven依赖

 
        
            org.apache.shiro
            shiro-core
            1.4.0
        
        
            org.apache.shiro
            shiro-web
            1.4.0
        
        
            org.apache.shiro
            shiro-ehcache
            1.4.0
        
        
            org.apache.shiro
            shiro-spring
            1.4.0
        
        
        
            com.github.theborakompanioni
            thymeleaf-extras-shiro
            2.0.0
        
        

2.新建缓存文件
ehcache-shiro.xml



    

    

    
    

3.重要的shiro配置类
不需要完全记住,只需要修改其中的一小部分

4.核心的授权认证类

import com.example.echart.entity.Permission;
import com.example.echart.entity.Role;
import com.example.echart.entity.User;
import com.example.echart.mapper.UserRoleMapper;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.session.mgt.eis.SessionDAO;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.support.DefaultSubjectContext;
import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

/**

 * @ Description:Shiro中最主要的代码,核心代码,用户认证授权处
 * @ Modified By:
 * @Version: $
 */
public class ShiroRealm extends AuthorizingRealm {


    @Autowired
    private SessionDAO sessionDAO;

    @Autowired
    private UserRoleMapper userRoleMapper;
    
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection auth) {
        //授权
        String username = (String)auth.getPrimaryPrincipal();
        System.out.println("进入到授权Realm中:"+username);

        List dbroleList = userRoleMapper.selectRoleList(username);
        List roleList=new ArrayList();
        for(Role r:dbroleList){
            roleList.add(r.getCode());
        }

        List dbpermissions = userRoleMapper.selectPermissionList(username);
        List permissionList=new ArrayList();
        for(Permission p:dbpermissions){
            permissionList.add(p.getPermission());
        }



//        roleList.add("ADMIN");
//        roleList.add("USER");

//        List permissionList=new ArrayList();
//        permissionList.add("ADMIN:USER:UPDATA");
//        permissionList.add("ADMIN:USER:DELETE");

        SimpleAuthorizationInfo simpleAuthorizationInfo=new SimpleAuthorizationInfo();
        simpleAuthorizationInfo.addRoles(roleList);
        simpleAuthorizationInfo.addStringPermissions(permissionList);

        return simpleAuthorizationInfo;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken auth) throws AuthenticationException {
        //认证
        String username = (String)auth.getPrincipal();
        System.out.println("进入到认证Realm中:"+username);

        //在认证之前判断当前登录用户,只允许一个账号登录
        Collection sessions = sessionDAO.getActiveSessions();
        for (Session session : sessions){
            String loginedUsername = String.valueOf(session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY));

            if(username.equals(loginedUsername)){
                session.setTimeout(0);
                break;
            }
        }


        //通过username在数据库中查询用户,判断密码
        User dbuser = userRoleMapper.selectByUserName(username);

        //通过用户名在数据库中拿到,判断用户名和密码对不对
        if(dbuser!=null){
            SimpleAuthenticationInfo authInfo = new SimpleAuthenticationInfo(username, dbuser.getPwd(), "userRealm");
            return authInfo;
        }

        return null;
    }
}

5.登录的Controller类,LoginController

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.crypto.hash.Md5Hash;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;

/**
 * @ Author     :Zgq
 * @ Date       :Created in 10:30 2019/6/12
 * @ Description:登录层方法
 * @ Modified By:
 * @Version: $
 */

@Controller
public class LoginController {

    //登录页面
    @RequestMapping(value = {"/login"})
    public String login(Map map) {
        map.put("msg","请登录");
        return "/shiro/login-page";
    }


    //登录成功页面
    @RequestMapping(value = {"/index"})
    public String index(Map map) {
        map.put("msg","登录成功");
        //获取用户信息
        Subject subject = SecurityUtils.getSubject();
        String username = (String)subject.getPrincipal();
        map.put("username",username);
        return "/shiro/index";
    }

    //登录请求
    @RequestMapping(value = {"/userLogin"})
    public String userLogin(String username, String pwd,boolean rememberMe, Map map)
    {
        Subject subject = SecurityUtils.getSubject();

        //根据自己盐加密的方式,放入密码
        String encodePwd = new Md5Hash(pwd, username).toString();

        UsernamePasswordToken auth = new UsernamePasswordToken(username, encodePwd,rememberMe);
        try {
            subject.login(auth);
            return "redirect:/index";
        }catch (Exception e){
            e.printStackTrace();
            map.put("msg","账号或密码错误");
            return "redirect:/login";
        }
    }


    //退出登录
    @RequestMapping(value = {"/loginOut"})
    public String loginOut(Map map) {

        //获取用户信息
        Subject subject = SecurityUtils.getSubject();
        subject.logout();

        map.put("msg","退出登录");
        return "redirect:/login";
    }


    /**
     * 加密的测试
     * @param args
     */
    public static void main(String[] args) {
        //加密
        String zhouguoqing = new Md5Hash("111", "admin1").toString();
        System.out.println(zhouguoqing);
    }
}

6.因为是和数据库直接对接的,所以我也新建了一个UserRoleMapper接口,返回数据

import com.example.echart.entity.Permission;
import com.example.echart.entity.Role;
import com.example.echart.entity.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Component;

import java.util.List;

@Mapper
@Component
public interface UserRoleMapper {

    /**
     * 通过登录名查询信息
     * @param username
     * @return
     * @throws Exception
     */
    @Select("select * from t_user where username=#{username} limit 1")
    User selectByUserName(String username);


    /**
     * 通过用户名查询用户角色信息
     * @param username
     * @return
     * @throws Exception
     */
    @Select("select * from t_user u,t_role r,t_user_role ur where u.username=#{username} and ur.userId=u.id and ur.roleId=r.id")
    List  selectRoleList(String username);


    /**
     * 通过用户名查找用户权限
     * @param username
     * @return
     */
    @Select("select * from t_permission p 
" +
            "where p.id in(
" +
            "	select permissionId from t_role_permission rp 
" +
            "	where rp.roleId in (
" +
            "			select ur.roleId from t_user_role ur where userId in(
" +
            "			select u.id from t_user u where u.username=#{username}
" +
            "			)
" +
            "	)
" +
            ")")
    List selectPermissionList(String username);



}

7.前台页面thymeleaf的展示




    
    Title




你好:

ADMIN角色

USER角色

SUPERMAN角色

UPDATA权限

DELETE权限

INSERT权限

SELECT权限

3.完成的效果

在这里插入图片描述
用不同用户登录之后会自动获取登录用户的角色和权限信息
