Struts2中使用HttpServletRequest和HttpServletResponse

一．非Ioc方式

這種方式主要是利用了com.opensymphony.xwork2.ActionContext類以及org.apache.struts2.ServletActionContext類，具體的方法如下所示。

獲得request對象：
1)．HttpServletRequest request = ServletActionContext.getRequest ();
2)．ActionContext ct= ActionContext.getContext();

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

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

二：IOC方式

Action在繼承ActionSupport的同時還要實現ServletRequestAware和ServletResponseAware接口

package com.iterator.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import com.opensymphony.xwork2.ActionSupport;

public class Struts2GetServletRequestAction extends ActionSupport implements
		ServletRequestAware, ServletResponseAware {

	private static final long serialVersionUID = 1L;
	private HttpServletRequest request;
	private HttpServletResponse response;
	
	public void setServletRequest(HttpServletRequest request) {
		this.request=request;
	}

	public void setServletResponse(HttpServletResponse response) {
		this.response=response;
	}

	@Override
	public String execute() throws Exception {
		System.out.println("requestUsername=" + request.getParameter("username") + ",requestPassword=" + request.getParameter("password"));
		return SUCCESS;
	}
}

這樣即可獲取從前臺的頁面傳遞的參數信息。
