Struts2实现上传单个文件功能

Struts2实现上传单个文件功能

upload.jsp 这个页面选择提交文件，提交到uploadImage.action

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

pageEncoding="utf-8"%>

please select the file:

FileUploadAction.java 将传来的file进行处理

package action;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import org.apache.commons.io.IOUtils;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class FileUploadAction extends ActionSupport{

private File upload;

private String uploadFileName;

private String uploadContentType;

public File getUpload() {

return upload;

}

public void setUpload(File upload) {

this.upload = upload;

}

public String getUploadFileName() {

return uploadFileName;

}

public void setUploadFileName(String uploadFileName) {

this.uploadFileName = uploadFileName;

}

public String getUploadContentType() {

return uploadContentType;

}

public void setUploadContentType(String uploadContentType) {

this.uploadContentType = uploadContentType;

}

public String execute(){

System.out.println(upload);

System.out.println(uploadContentType);

System.out.println(uploadFileName);

String savePath = ServletActionContext.getServletContext().getRealPath("/upload/"+this.uploadFileName);

System.out.println(savePath);

try{

FileInputStream fis = new FileInputStream(upload);

FileOutputStream fos = new FileOutputStream(savePath);

IOUtils.copy(fis, fos);

fos.flush();

fos.close();

fis.close();

}catch(Exception e){

e.printStackTrace();

}

return "success";

}

}

uploadFileName和uploadContentType，这两个属性分别用于封装上传文件的文件名、上传文件的文件类型

Struts.xml配置

uploadSuccess.jsp

uploadError.jsp

成功失败界面随便写一个就行了，不贴了。
