SpringMVC获取request对象和response对象

其他Action继承BaseAction

方法一：

1、BaseAction类

[java] view
plaincopy

public class BaseAction {

protected HttpServletRequest request;

protected HttpServletResponse response;

protected HttpSession session;

@ModelAttribute

public 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

[java] view
plaincopy

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

[java] view
plaincopy

<listener>

<span style="white-space:pre"> </span><listener-class>org.springframework.web.context.request.RequestContentListener</listener-class>

</listener>
