SpringMVC获取request对象和response对象

其他Action继承BaseAction

方法一：

1、BaseAction类

public class BaseAction {protected HttpServletRequest request;protected HttpServletResponse response;protected HttpSession session;@ModelAttributepublic void setReqAndRes(HttpServletRequest request, HttpServletResponse response){this.request = request;this.response = response;this.session = request.getSession();}

说明：ModelAttribute的作用

1)放置在方法的形参上：表示引用Model中的数据

2)放置在方法上面：表示请求该类的每个Action前都会首先执行它，也可以将一些准备数据的操作放置在该方法里面。

方法二：

1、BaseAction类

public class BaseAction {protected HttpServletRequest request;protected HttpServletResponse response;protected HttpSession session;HttpServletRequest request1 = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();HttpServletResponse response1 = ((ServletWebRequest)RequestContextHolder.getRequestAttributes()).getResponse();

2、web.xml

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