struts2的Action中取得HttpServletRequest的方法

1、Action类需要实现org.apache.struts2.interceptor.ServletRequestAware接口

2、实现ServletRequestAware接口的方法：public void setServletRequest(HttpServletRequest request);

例如：

package com.zhaozhy.action;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.interceptor.ServletRequestAware;

import com.opensymphony.xwork2.ActionSupport;

/**
 *
 * @author zhaozhy
 *
 */
public class MoreSubmitAction extends ActionSupport implements
  ServletRequestAware {

 private String msg;
 private HttpServletRequest request;

 public void setServletRequest(HttpServletRequest request) {

  this.request = request;
 }

 public String save() {
  request.setAttribute("result", "成功保存[" + msg + "]");
  return "save";
 }

 public String print() {

  request.setAttribute("result", "成功打印[" + msg + "]");

  return "print";
 }

 public String getMsg() {
  return msg;
 }

 public void setMsg(String msg) {
  this.msg = msg;
 }
 
 

}
