Struts2中文件上传

  • Html界面代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
<form method="post" action="index" enctype="multipart/form-data">
文件：<input type="file" name="uploadImage" /><br />
<input type="submit" value="submit">
</form>
</body>
</html>
  • 编写Action部分：

简述：

提供属性并且给出get/set方法

1.uploadImage文件

2.文件名uploadImageFileName

通过函数：FileUtils.copyFile(srcFile, destFile);达到上传目的。

package com.zhangpn.struts2;

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

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

public class Helloworld {
	private File uploadImage;
	private String uploadImageFileName;

	public String execute() {
		String reslpath = ServletActionContext.getServletContext().getRealPath("/images");//获取绝对路径
		if(uploadImage!=null) {
			File savepath = new File(new File(reslpath),uploadImageFileName);//创建保存文件信息
			if(!savepath.getParentFile().exists()) {
				savepath.getParentFile().mkdirs();
			}
			try {
				FileUtils.copyFile(uploadImage, savepath);
				System.out.println("upload success...");
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		return "success";
	}

	public File getUploadImage() {
		return uploadImage;
	}

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

	public String getUploadImageFileName() {
		return uploadImageFileName;
	}

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