Struts2中使用HttpServletRequest和HttpServletResponse

一．非Ioc方式

这种方式主要是利用了com.opensymphony.xwork2.ActionContext类以及org.apache.struts2.ServletActionContext类，具体的方法如下所示。

获得request对象：
1)．HttpServletRequest request = ServletActionContext.getRequest ();
2)．ActionContext ct= ActionContext.getContext();

       HttpServletRequest request=(HttpServletRequest)ct.get(ServletActionContext.HTTP_REQUEST);

获得response对象：
1)．HttpServletResponse response= ServletActionContext.getResponse ();
2)．ActionContext ct= ActionContext.getContext();
       HttpServletResponse response=(HttpServletResponse )ct.get(ServletActionContext.HTTP_RESPONSE);

二：IOC方式

Action在继承ActionSupport的同时还要实现ServletRequestAware和ServletResponseAware接口

[java] view plain copy

1. package com.iterator.action;  
2.   
3. import javax.servlet.http.HttpServletRequest;  
4. import javax.servlet.http.HttpServletResponse;  
5.   
6. import org.apache.struts2.interceptor.ServletRequestAware;  
7. import org.apache.struts2.interceptor.ServletResponseAware;  
8.   
9. import com.opensymphony.xwork2.ActionSupport;  
10.   
11. public class Struts2GetServletRequestAction extends ActionSupport implements  
12.         ServletRequestAware, ServletResponseAware {  
13.   
14.     private static final long serialVersionUID = 1L;  
15.     private HttpServletRequest request;  
16.     private HttpServletResponse response;  
17.       
18.     public void setServletRequest(HttpServletRequest request) {  
19.         this.request=request;  
20.     }  
21.   
22.     public void setServletResponse(HttpServletResponse response) {  
23.         this.response=response;  
24.     }  
25.   
26.     @Override  
27.     public String execute() throws Exception {  
28.         System.out.println("requestUsername=" + request.getParameter("username") + ",requestPassword=" + request.getParameter("password"));  
29.         return SUCCESS;  
30.     }  
31. }
