struts2的下载文件

1、首先创建一个Action

package com.lanou.mp.controller;

import java.io.InputStream;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class FileDownLoadAction extends ActionSupport {

 InputStream fileStream;

         String name;

public String downLoad() {

//获取下载文件流

   fileStream=ServletActionContext.getServletContext().getResourceAsStream("download/"+name);

   

return SUCCESS;

}

public InputStream getFileStream() {

return fileStream;

}

public void setFileStream(InputStream fileStream) {

this.fileStream = fileStream;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}
