Spring gets the session and request in the normal class

When using spring, it is often necessary to get session,request in common classes.
For example, some AOP interceptor classes, when using STRUTS2, because Struts2 has an interface to use the Org.apache.struts2.ServletActionContext can be easily taken to the session of the image.
Usage: servletactioncontext.getrequest (). GetSession ();

But how do you get session,reuqest in a normal class when you use spring alone?
First, add the following code to the Web. xml:

<listener>        <listener-class> org.springframework.web.context.request.requestcontextlistener</listener-class> </listener >

How to use:

　　In the normal bean

@Autowired   Private HttpSession session;    @Autowired  private httpservletrequest request;  

　In the normal class

HttpServletRequest request = ((servletrequestattributes) requestcontextholder.getrequestattributes ()). GetRequest () ;
