今天要使用struts2 的文件下载，先写了个demo，怎么也调不通，请大家指导一下。
后台代码：

public class DownloadFileAction extends ActionSupport {

	/**

	 * 

	 */

	private static final long serialVersionUID = -4434797914813536697L;

	private InputStream inputStream;

    private String fileName;

    private long contentLength;

 

    public String execute() throws FileNotFoundException {

         

        File fileToDownload = new File("D:/DownLoad/fileABC.txt");

 

        inputStream = new FileInputStream(fileToDownload);

        fileName = fileToDownload.getName();

        contentLength = fileToDownload.length();

         

        return SUCCESS;

    }

struts.xml 文件：

<package name="Struts2FileDownload" extends="struts-default">

         

        <action name="downloadFile" class="com.ryf.action.DownloadFileAction">

            <result name="success" type="stream">

                <param name="contentType">text/plain</param>

                <param name="inputName">inputStream</param>

                <param name="contentDisposition">attachment;filename="${fileName}"</param>

                <param name="bufferSize">4096</param>

            </result>

        </action>

         

    </package>

前台代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
