Question

@RequestMapping("/User.html");
@sessionAttributes("user");
class something

Now i know that @Controller = implements Controller

@requestMaping =   <bean name="/user.html"

now i don't know which thing is equal to @sessionAttributes("user"); if i don't use annotation

Answer 1

@SessionAttributes是声明模型对象的另一种方式，您也可以将其用作@ModelAttribute或标准创建新对象。

Answer 2

@SessionAttributes等于对session.setAttribute()调用，您通常会在servlet的某个地方进行调用以将对象放入会话中。
