Tambah pemintas, tetapkan UUID sebagai pengecam unik dan simpannya dalam pangkalan data
Pertanyaan melalui akaun log masuk semasa
Jika pada masa ini Jika nilai UUID yang disimpan dalam sesi pengguna adalah sama dengan nilai UUID dalam pangkalan data kami, berikan
sebaliknya kembali palsu, menunjukkan bahawa pengguna telah log masuk pada peranti atau penyemak imbas lain
Mula-mula kami mencipta projek Spring baharu
Tambah kebergantungan berikut

Buat pakej berikut dalam direktori java, dan cipta pemeta pakej dalam sumber
Mula-mula tulis kelas entiti lapisan pojo Pengguna
Nota: Apabila mencipta jadual dalam MySQL, jenis data uuid ialah varchar dan panjang mestilah lebih besar, jika tidak ia akan berjalan Laporkan ralat
package com.bdqn.springsso.pojo; import lombok.Data; @Data public class User { //用户id private Integer id; //账户 private String username; //密码 private String password; //uuid private String uuid; }
Kemudian tulis antara muka UserMapper lapisan pemeta
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 { //根据姓名和密码查询 User chekLogin(@Param("username") String username, @Param("password") String password); //根据姓名修改uuid void update(@Param("uuid") String uuid,@Param("username") String username); //根据姓名查询uuid String getUUID(@Param("username") String username); }
Kemudian tulis lapisan perkhidmatan UserService dan UserServiceImpl
package com.bdqn.springsso.service; import com.bdqn.springsso.pojo.User; public interface UserService { //根据姓名和密码查询 User chekLogin(String username, String password); //根据姓名修改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); } }
Kemudian tulis lapisan pemintas UserInterceptor pemintas
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"); //数据库 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("拦截"+request.getRequestURI()); response.sendRedirect("/login"); response.setStatus(401); return false; } } }
Kemudian lapisan pengawal 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; //登录 @RequestMapping("/") public String goLogin(){ return "login"; } //登录验证 @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"; } } //测试 @RequestMapping("/test") @ResponseBody public String test(){ return "成功"; } }
Kemudian penulisan lapisan konfigurasi MvcConfig
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) { //添加拦截器,排除/路径和 /login路径 registry.addInterceptor(new UserInterceptor(userMapper)) .excludePathPatterns("/","/login"); } }
Yang terakhir ialah penulisan userMapper.xml
<?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>

Mula-mula kami menggunakan pelayar Firefox untuk beroperasi
Masukkan http:// localhost:8080/Masukkan halaman log masuk
Klik untuk log masuk
Klik untuk menguji
Kemudian kami kembali ke halaman kejayaan log masuk
Gunakan Google Chrome untuk memasukkan http://localhost:8080/ ke log masuk
Selepas log masuk, masukkan halaman kejayaan log masuk
Pada masa ini kita kembali ke pelayar Firefox
Klik hiperpautan ujian untuk mendapati halaman tersebut melompat ke halaman log masuk
Menandakan ujian log masuk tunggal berjaya
