這篇文章主要介紹了SpringBoot單點(diǎn)登錄怎么實(shí)現(xiàn)的相關(guān)知識(shí),內(nèi)容詳細(xì)易懂,操作簡(jiǎn)單快捷,具有一定借鑒價(jià)值,相信大家閱讀完這篇SpringBoot單點(diǎn)登錄怎么實(shí)現(xiàn)文章都會(huì)有所收獲,下面我們一起來(lái)看看吧。
添加攔截器,設(shè)置UUID作為唯一標(biāo)識(shí),存入數(shù)據(jù)庫(kù)中
通過(guò)當(dāng)前登陸者的賬戶進(jìn)行查詢
如果當(dāng)前登陸者session中存入的UUID與我們數(shù)據(jù)庫(kù)中的UUID值相同則通過(guò)
否則返回false,表示已在其他設(shè)備或?yàn)g覽器登錄登錄
首先我們新建一個(gè)Spring項(xiàng)目
添加以下幾個(gè)依賴
yml配置文件
server:
port: 8080
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/userdb?characterEncoding=utf-8&&severTimezone=utc
username: root
password: root
thymeleaf:
mode: HTML5
cache: false
suffix: .html
prefix: classpath:/templates/
mybatis:
mapper-locations: classpath:/mapper/*.xml #引入mapper文件
type-aliases-package: com.bdqn.springsso.pojo #引入類(lèi)型別名
pom.xml配置文件

在java目錄下建立以下幾個(gè)包,并在resources中建立mapper包
首先進(jìn)行 pojo層 實(shí)體類(lèi)User 的編寫(xiě)
注意:在MySQL中創(chuàng)建表時(shí) uuid 的數(shù)據(jù)類(lèi)型為 varchar 長(zhǎng)度一定要給大一點(diǎn)不然就會(huì)運(yùn)行報(bào)錯(cuò)
package com.bdqn.springsso.pojo; import lombok.Data; @Data public class User { //用戶id private Integer id; //賬戶 private String username; //密碼 private String password; //uuid private String uuid; }
再進(jìn)行 mapper層 UserMapper接口 的編寫(xiě)
package com.bdqn.springsso.mapper; import com.bdqn.springsso.pojo.User; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; @Mapper public interface UserMapper { //根據(jù)姓名和密碼查詢 User chekLogin(@Param("username") String username, @Param("password") String password); //根據(jù)姓名修改uuid void update(@Param("uuid") String uuid,@Param("username") String username); //根據(jù)姓名查詢uuid String getUUID(@Param("username") String username); }
再進(jìn)行 service層 UserService 和 UserServiceImpl 的編寫(xiě)
package com.bdqn.springsso.service; import com.bdqn.springsso.pojo.User; public interface UserService { //根據(jù)姓名和密碼查詢 User chekLogin(String username, String password); //根據(jù)姓名修改uuid void update(String uuid,String username); }
package com.bdqn.springsso.service; import com.bdqn.springsso.mapper.UserMapper; import com.bdqn.springsso.pojo.User; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service public class UserServiceImpl implements UserService { @Autowired private UserMapper userMapper; @Override public User chekLogin(String username, String password) { return userMapper.chekLogin(username,password); } @Override public void update(String uuid,String username) { userMapper.update(uuid,username); } }
再是 interceptor層 UserInterceptor攔截器 的編寫(xiě)
package com.bdqn.springsso.interceptor; import com.bdqn.springsso.mapper.UserMapper; import org.springframework.web.servlet.HandlerInterceptor; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; public class UserInterceptor implements HandlerInterceptor { private UserMapper userMapper; public UserInterceptor(UserMapper userMapper){ this.userMapper=userMapper; } @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { HttpSession session = request.getSession(); String username = (String) session.getAttribute("username"); //數(shù)據(jù)庫(kù) String UUID=userMapper.getUUID(username); //session String uuid = (String)session.getAttribute("uuid"); System.out.println("uuid = " + uuid); System.out.println("UUID = " + UUID); if(UUID.equals(uuid)){ return true; }else { System.out.println("攔截"+request.getRequestURI()); response.sendRedirect("/login"); response.setStatus(401); return false; } } }
再是 controller層 UserController
package com.bdqn.springsso.controller; import com.bdqn.springsso.pojo.User; import com.bdqn.springsso.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.CrossOrigin; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import javax.servlet.http.HttpSession; import java.util.UUID; @Controller @CrossOrigin public class UserController { @Autowired private UserService userService; //登錄 @RequestMapping("/") public String goLogin(){ return "login"; } //登錄驗(yàn)證 @RequestMapping("/login") public String chekLogin(String username, String password, HttpSession session){ User user=userService.chekLogin(username,password); if (user==null){ return "login"; }else { session.setAttribute("username",username); String uuid= UUID.randomUUID().toString().replace("-", ""); System.out.println("uuid = " + uuid); userService.update(uuid,username); session.setAttribute("uuid",uuid); return "index"; } } //測(cè)試 @RequestMapping("/test") @ResponseBody public String test(){ return "成功"; } }
再是 config層 MvcConfig 的編寫(xiě)
package com.bdqn.springsso.config; import com.bdqn.springsso.interceptor.UserInterceptor; import com.bdqn.springsso.mapper.UserMapper; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.InterceptorRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configuration public class MvcConfig implements WebMvcConfigurer { @Autowired private UserMapper userMapper; @Override public void addInterceptors(InterceptorRegistry registry) { //添加攔截器,排除/路徑和 /login路徑 registry.addInterceptor(new UserInterceptor(userMapper)) .excludePathPatterns("/","/login"); } }
最后是 userMapper.xml 的編寫(xiě)
<?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.bdqn.springsso.mapper.UserMapper"> <update id="update"> update user set uuid=#{uuid} where username=#{username} </update> <select id="chekLogin" resultType="com.bdqn.springsso.pojo.User"> select * from user where username=#{username} and password=#{password} </select> <select id="getUUID" resultType="java.lang.String"> select uuid from user where username=#{username} </select> </mapper>
login.html
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>Login Module</title> </head> <body> <h2 >歡迎來(lái)到登錄頁(yè)面</h2> <form th:action="@{/login}" method="post"> 用戶:<input type="text" name="username"><br> 密碼:<input type="password" name="password"><br> <button type="submit">登錄</button> </form> </body> </html>

首先我們用火狐瀏覽器進(jìn)行操作
輸入http://localhost:8080/進(jìn)入登陸頁(yè)面
點(diǎn)擊登錄
點(diǎn)擊測(cè)試
然后我們返回登陸成功頁(yè)面
再用谷歌瀏覽器進(jìn)入http://localhost:8080/進(jìn)行登錄操作
登錄后進(jìn)入登錄成功頁(yè)面
此時(shí)我們返回火狐瀏覽器
點(diǎn)擊測(cè)試超鏈接 發(fā)現(xiàn)頁(yè)面跳轉(zhuǎn)至登錄頁(yè)面
表明單點(diǎn)登錄測(cè)試成功
