1、登錄方法：login

@PostMapping("/user/login")public ResponseVo<User> login(@Valid @RequestBody UserLoginForm userLoginForm,HttpSession session) {ResponseVo<User> userResponseVo = userService.login(userLoginForm.getUsername(), userLoginForm.getPassword());//設置Sessionsession.setAttribute(MallConst.CURRENT_USER, userResponseVo.getData());log.info("/login sessionId={}", session.getId());return userResponseVo;}

2、獲取用戶信息：user

//session保存在內存里，改進版：token+redis@GetMapping("/user")public ResponseVo<User> userInfo(HttpSession session) {log.info("/user sessionId={}", session.getId());User user = (User) session.getAttribute(MallConst.CURRENT_USER);return ResponseVo.success(user);}

3、退出方法：logout

@PostMapping("/user/logout")public ResponseVo logout(HttpSession session) {log.info("/user/logout sessionId={}", session.getId());session.removeAttribute(MallConst.CURRENT_USER);return ResponseVo.success();}
