SpringBoot登录、退出、获取用户信息的session处理

1、登录方法：login

@PostMapping("/user/login")
	public ResponseVo login(@Valid @RequestBody UserLoginForm userLoginForm,
								  HttpSession session) {
		ResponseVo userResponseVo = userService.login(userLoginForm.getUsername(), userLoginForm.getPassword());

		//设置Session
		session.setAttribute(MallConst.CURRENT_USER, userResponseVo.getData());
		log.info("/login sessionId={}", session.getId());

		return userResponseVo;
	}

2、获取用户信息：user

//session保存在内存里，改进版：token+redis
	@GetMapping("/user")
	public ResponseVo 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();
	}
