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"%>
<!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title>insert title here</title>
</head>
<body>
  <form action="uploadimage.action" enctype="multipart/form-data" method="post">
    please select the file:<input type="file" name="upload">
    <input type="submit" value="上传文件">
  </form>
</body>
</html>

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

<action name="uploadimage" class="action.fileuploadaction">
 <result name="success">uploadsuccess.jsp</result>
 <result name="input">uploaderror.jsp</result>
</action>

成功失败界面随便写一个就行了，不贴了。
