使用redis实现分布式session

package com.example.fbssession.controller; import com.example.fbssession.entity.User; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.servlet.http.HttpSession; import java.util.HashMap; import java.util.Map; @RestController @RequestMapping(value = "/user") public class UserController { Map<String, User> userMap = new HashMap<>(); //初始化用户，模拟登陆 public UserController(){ User u1 = new User(1, "test", "test"); userMap.put("test", u1); } //登陆，根据用户名密码验证 @GetMapping(value = "/login") public String login(String username, String password, HttpSession session){ User user = this.userMap.get(username);//模拟数据库连接查找 if(user != null){ if(!password.equals(user.getPassword())){ return "用户名或者密码错误"; }else{ session.setAttribute(session.getId(),user); return "登陆成功"; } }else{ return "用户名或者密码错误"; } } @GetMapping(value = "/session") public String session(HttpSession session){ return session.getId(); } //退出登陆 @GetMapping(value = "/loginout") public String loginout(HttpSession session){ //清除sessionid session.removeAttribute(session.getId()); return "成功退出"; } }
