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

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