springboot+shiro+redis項目整合

介紹：

　　Apache Shiro是一個強大且易用的Java安全框架,執行身份驗證、授權、密碼學和會話管理。使用Shiro的易於理解的API,您可以快速、輕松地獲得任何應用程序,從最小的移動應用程序到最大的網絡和企業應用程序。（摘自百度百科）

本文使用springboot+mybatisplus＋shiro實現數據庫動態的管理用戶、角色、權限管理，在本文的最后我會提供源碼的下載地址，想看到效果的小伙伴可以直接下載運行就ok了

因為shiro的功能比較多，本章只介紹如下幾個功能

　　1.當用戶沒有登陸時只能訪問登陸界面

　　2.當用戶登陸成功后，只能訪問該用戶下僅有的權限

　　3.一個用戶不能兩個人同時在線

一、數據庫設計

　　本文的數據庫表為5個分別是： 用戶表、角色表、權限表、用戶角色中間表、角色權限中間表，表的結構和數據項目中會提供（sql和redis工具下方的下載地址中都會有）

 

二、引入依賴

 三、編輯application.yml

server:
  port: 8080

spring:
  mvc:
    view:
      prefix: /WEB-INF/jsp/
      suffix: .jsp
  datasource:
    url: jdbc:mysql://localhost:3306/shiro?characterEncoding=UTF-8&useUnicode=true&useSSL=false
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver

  redis:
    host: localhost
    port: 6379
    jedis:
      pool:
        max-idle: 8
        min-idle: 0
        max-active: 8
        max-wait: -1
    timeout: 0

mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.chaoqi.springboot_mybatisplus.domain

 四、創建ShiroConfig配置

package com.chaoqi.springboot_shiro_redis.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.servlet.Filter;
import java.util.LinkedHashMap;
import java.util.Map;


@Configuration
public class ShiroConfig {

    @Bean

        // 沒有登陸的用戶只能訪問登陸頁面
        shiroFilterFactoryBean.setLoginUrl("/auth/login");
        // 登錄成功后要跳轉的鏈接
        shiroFilterFactoryBean.setSuccessUrl("/auth/index");

        filtersMap.put("kickout", kickoutSessionControlFilter());
        shiroFilterFactoryBean.setFilters(filtersMap);
        // 權限控制map.

}

五、自定義Realm

package com.chaoqi.springboot_shiro_redis.secutity;

import com.chaoqi.springboot_shiro_redis.service.SysRoleService;
import com.chaoqi.springboot_shiro_redis.service.UserService;
import com.chaoqi.springboot_shiro_redis.dao.domain.SysUser;
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.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.*;

public class MyShiroRealm extends AuthorizingRealm {
    private static org.slf4j.Logger logger = LoggerFactory.getLogger(MyShiroRealm.class);

    //如果項目中用到了事物，@Autowired注解會使事物失效，可以自己用get方法獲取值
    @Autowired
    private SysRoleService roleService;
    @Autowired
    private UserService userService;

    /**
     * 認證信息.(身份驗證) : Authentication 是用來驗證用戶身份
     *
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
        logger.info("---------------- 執行 Shiro 憑證認證 ----------------------");
        UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
        String name = token.getUsername();
        String password = String.valueOf(token.getPassword());
        SysUser user = new SysUser();
        user.setUserName(name);
        user.setPassWord(password);
        // 從數據庫獲取對應用戶名密碼的用戶
        SysUser userList = userService.getUser(user);
        if (userList != null) {
            // 用戶為禁用狀態
            if (userList.getUserEnable() != 1) {
                throw new DisabledAccountException();
            }
            logger.info("---------------- Shiro 憑證認證成功 ----------------------");
            SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
                    userList, //用戶
                    userList.getPassWord(), //密碼
                    getName()  //realm name
            );
            return authenticationInfo;
        }
        throw new UnknownAccountException();
    }

    /**
     * 授權
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        logger.info("---------------- 執行 Shiro 權限獲取 ---------------------");
        Object principal = principals.getPrimaryPrincipal();
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        if (principal instanceof SysUser) {
            SysUser userLogin = (SysUser) principal;
            Set<String> roles = roleService.findRoleNameByUserId(userLogin.getId());
            authorizationInfo.addRoles(roles);

            Set<String> permissions = userService.findPermissionsByUserId(userLogin.getId());
            authorizationInfo.addStringPermissions(permissions);
        }
        logger.info("---- 獲取到以下權限 ----");
        logger.info(authorizationInfo.getStringPermissions().toString());
        logger.info("---------------- Shiro 權限獲取成功 ----------------------");
        return authorizationInfo;
    }

}

六、限制並發人數登陸

package com.chaoqi.springboot_shiro_redis.secutity;

import com.alibaba.fastjson.JSON;
import com.chaoqi.springboot_shiro_redis.dao.domain.SysUser;
import org.apache.shiro.cache.Cache;

import org.apache.shiro.session.mgt.DefaultSessionKey;
import org.apache.shiro.session.mgt.SessionManager;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.web.filter.AccessControlFilter;
import org.apache.shiro.web.util.WebUtils;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Serializable;
import java.util.Deque;
import java.util.HashMap;
import java.util.LinkedList;
import java.util.Map;

public class KickoutSessionControlFilter extends AccessControlFilter {

    private String kickoutUrl; //踢出后到的地址
    private boolean kickoutAfter = false; //踢出之前登錄的/之后登錄的用戶 默認踢出之前登錄的用戶
    private int maxSession = 1; //同一個帳號最大會話數 默認1

    private SessionManager sessionManager;
    private Cache<String, Deque<Serializable>> cache;

    public void setKickoutUrl(String kickoutUrl) {
        this.kickoutUrl = kickoutUrl;
    }

    public void setKickoutAfter(boolean kickoutAfter) {
        this.kickoutAfter = kickoutAfter;
    }

    public void setMaxSession(int maxSession) {
        this.maxSession = maxSession;
    }

    public void setSessionManager(SessionManager sessionManager) {
        this.sessionManager = sessionManager;
    }
    //設置Cache的key的前綴
    public void setCacheManager(CacheManager cacheManager) {
        this.cache = cacheManager.getCache("shiro_redis_cache");
    }

    @Override
    protected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {
        return false;
    }

    @Override
    protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
        Subject subject = getSubject(request, response);
        if(!subject.isAuthenticated() && !subject.isRemembered()) {
            //如果沒有登錄，直接進行之后的流程
            return true;
        }


        Session session = subject.getSession();
        SysUser user = (SysUser) subject.getPrincipal();
        String username = user.getUserName();
        Serializable sessionId = session.getId();

        //讀取緩存   沒有就存入
        Deque<Serializable> deque = cache.get(username);

        //如果此用戶沒有session隊列，也就是還沒有登錄過，緩存中沒有
        //就new一個空隊列，不然deque對象為空，會報空指針
        if(deque==null){
            deque = new LinkedList<Serializable>();
        }

        //如果隊列里沒有此sessionId，且用戶沒有被踢出；放入隊列
        if(!deque.contains(sessionId) && session.getAttribute("kickout") == null) {
            //將sessionId存入隊列
            deque.push(sessionId);
            //將用戶的sessionId隊列緩存
            cache.put(username, deque);
        }

        //如果隊列里的sessionId數超出最大會話數，開始踢人
        while(deque.size() > maxSession) {
            Serializable kickoutSessionId = null;
            if(kickoutAfter) { //如果踢出后者
                kickoutSessionId = deque.removeFirst();
                //踢出后再更新下緩存隊列
                cache.put(username, deque);
            } else { //否則踢出前者
                kickoutSessionId = deque.removeLast();
                //踢出后再更新下緩存隊列
                cache.put(username, deque);
            }



            try {
                //獲取被踢出的sessionId的session對象
                Session kickoutSession = sessionManager.getSession(new DefaultSessionKey(kickoutSessionId));
                if(kickoutSession != null) {
                    //設置會話的kickout屬性表示踢出了
                    kickoutSession.setAttribute("kickout", true);
                }
            } catch (Exception e) {//ignore exception
            }
        }

        //如果被踢出了，直接退出，重定向到踢出后的地址
        if (session.getAttribute("kickout") != null) {
            //會話被踢出了
            try {
                //退出登錄
                subject.logout();
            } catch (Exception e) { //ignore
            }
            saveRequest(request);

            Map<String, String> resultMap = new HashMap<String, String>();
            //判斷是不是Ajax請求
            if ("XMLHttpRequest".equalsIgnoreCase(((HttpServletRequest) request).getHeader("X-Requested-With"))) {
                resultMap.put("user_status", "300");
                resultMap.put("message", "您已經在其他地方登錄，請重新登錄！");
                //輸出json串
                out(response, resultMap);
            }else{
                //重定向
                WebUtils.issueRedirect(request, response, kickoutUrl);
            }
            return false;
        }
        return true;
    }
    private void out(ServletResponse hresponse, Map<String, String> resultMap)
            throws IOException {
        try {
            hresponse.setCharacterEncoding("UTF-8");
            PrintWriter out = hresponse.getWriter();
            out.println(JSON.toJSONString(resultMap));
            out.flush();
            out.close();
        } catch (Exception e) {
            System.err.println("KickoutSessionFilter.class 輸出JSON異常，可以忽略。");
        }
    }
}

七、異常處理類，攔截未授權頁面（未授權頁面有三種實現方式，我這里使用異常處理）

 

package com.chaoqi.springboot_shiro_redis.exception;

import org.apache.shiro.authz.AuthorizationException;
import org.apache.shiro.authz.UnauthorizedException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;

/**
 * 全局異常處理類
 */
@ControllerAdvice
public class CtrlExceptionHandler {
    private static Logger logger = LoggerFactory.getLogger(CtrlExceptionHandler.class);

    //攔截未授權頁面
    @ResponseStatus(value = HttpStatus.FORBIDDEN)
    @ExceptionHandler(UnauthorizedException.class)
    public String handleException(UnauthorizedException e) {
        logger.debug(e.getMessage());
        return "403";
    }

    @ResponseStatus(value = HttpStatus.FORBIDDEN)
    @ExceptionHandler(AuthorizationException.class)
    public String handleException2(AuthorizationException e) {
        logger.debug(e.getMessage());
        return "403";
    }
}

 八、最后附上logincontroller的代碼，調用login就可以調到登陸頁面

package com.chaoqi.springboot_shiro_redis.web;

import com.chaoqi.springboot_shiro_redis.dao.domain.SysUser;
import com.chaoqi.springboot_shiro_redis.utils.RequestUtils;
import org.apache.commons.lang3.StringUtils;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.DisabledAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;


@Controller
@RequestMapping(value = "/auth")
public class LoginController {

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String submitLogin(String username, String password, HttpServletRequest request) {
        try {
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);
            Subject subject = SecurityUtils.getSubject();
            subject.login(token);
            SysUser user = (SysUser) subject.getPrincipal();
        } catch (DisabledAccountException e) {
            request.setAttribute("msg", "賬戶已被禁用");
            return "login";
        } catch (AuthenticationException e) {
            request.setAttribute("msg", "用戶名或密碼錯誤");
            return "login";
        }

        // 執行到這里說明用戶已登錄成功
        return "redirect:/auth/index";
    }


    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String loginPage() {
        return "login";
    }

    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String loginSuccessMessage(HttpServletRequest request) {
        String username = "未登錄";
        SysUser currentLoginUser = RequestUtils.currentLoginUser();

        if (currentLoginUser != null && StringUtils.isNotEmpty(currentLoginUser.getUserName())) {
            username = currentLoginUser.getUserName();
        } else {
            return "redirect:/auth/login";
        }
        request.setAttribute("username", username);
        return "index";
    }

    //被踢出后跳轉的頁面
    @RequestMapping(value = "/kickout", method = RequestMethod.GET)
    public String kickOut() {
        return "kickout";
    }
}
