前台

前台页面代码

<%@ page language="java" pageEncoding="utf-8" contentType="text/html; charset=utf-8"%>
<%@ taglib uri="/struts-tags"   prefix="s"%>
<html>
<head>
    <title>My JSP 'index.jsp' starting page</title>
    </head>
<body>

    <form action="upload/uploadAction_saveFile.fcy"
          name="form1" method="post" enctype="multipart/form-data" >

             上传文件名称:<input type="file" name="uploadImage">
           <input type="submit" value="上传">
    </form>
</body>
</html>

(uploadAction_saveFile.fcy是自己改的，其默认的是.action或者不写)

文件类型

uploadAction.java的文件

package com.deppon.upload;

import java.io.File;
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.io.FileUtils;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class UploadAction extends ActionSupport {

   //文件上传
    //struts2文件上传下载的规则
   //uploadImage:必须是前台的页面name的属性但是类型必须是File类型，是一个路径名：（实际上是上传的临时文件）
   //uploadImageContentType:实际是    上传文件的类型
   //uploadImageFileName:实际是           上传文件的名
   private File uploadImage;

   private String uploadImageContentType;

   private String uploadImageFileName;

   public String saveFile(){
       System.out.println("UploadAction------>saveFile--->");
        /*HttpServletRequest request = ServletActionContext.getRequest();

       String path = request.getRealPath("/fileupload");*/
       //获取文件路径
       String path = ServletActionContext.getServletContext().getRealPath("/fileupload");
       /*System.out.println(path);
       System.out.println(uploadImageContentType);
       System.out.println(uploadImageFileName);*/
       File storeFile = new File(path+"\\"+uploadImageFileName);
       System.out.println(storeFile);
       try {
           FileUtils.copyFile(uploadImage, storeFile);
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
       return "success";
   }

   public File getUploadImage() {
       return uploadImage;
   }

   public void setUploadImage(File uploadImage) {
       this.uploadImage = uploadImage;
   }

   public String getUploadImageContentType() {
       return uploadImageContentType;
   }

   public void setUploadImageContentType(String uploadImageContentType) {
       this.uploadImageContentType = uploadImageContentType;
   }

   public String getUploadImageFileName() {
       return uploadImageFileName;
   }

   public void setUploadImageFileName(String uploadImageFileName) {
       this.uploadImageFileName = uploadImageFileName;
   }



}
