springMVC 中获取request、response、session方法

为springMVC获取request,response,Session的方法

@Controller
public class UserControll{
    /*1、可以只用注解直接注入*/
    @Autowired 
        private HttpServletRequest request;
        @Autowired 
        private HttpServletResponse response;
        @Autowired
        private HttpSession session;
    /*2、可以直接在处理函数的参数中引入,其中session也可以通过request获得*/
    @RequestMapping(value="" method=RequestMethod.POST)
    public String doSomething(HttpServletRequest request,HttpServletResponse response,HttpSession session){}</span>
