一、SpringMVC中获取request、response对象

方法一：

BaseAction.java

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：

public class BaseAction {

protected HttpServletRequest request;

protected HttpServletResponse response;

protected HttpSession session;

1.注解法

@Autowired

private  HttpServletRequest request;

2.直接取

HttpServletRequest request1 = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();

HttpServletResponse response1 = ((ServletWebRequest)RequestContextHolder.getRequestAttributes()).getResponse();

3.在web点xml中配置一个监听

<listener>  

        <listener-class>  

            org.springframework.web.context.request.RequestContextListener  

        </listener-class>  

</listener>  

二、Struts2中获取request、response对象

HttpServletRequest request = ServletActionContext.getRequest();
