HttpSession session 对象获取的方式

一、通过接口方法的参数直接获取

eg:

public Result login(@RequestBody LoginFormDTO loginForm, HttpSession session){
    return userService.login(loginForm,session);
}

二、通过HttpServletRequest对象获取

eg:

//注入对象
@Autowired
private HttpServletRequest requset;

public Result login(LoginFormDTO loginForm) {
        HttpSession session = requset.getSession();
    ...
}
