1、upload.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>my file upload</title>
</head>
<body>
<s:form action="uploadAction" method="post" enctype="multipart/form-data">
<s:file name="upload" label="文件上传"></s:file>
<s:submit value="上传"></s:submit>
</s:form>
</body>
</html>
2、struts.xml
<struts>
<!-- <constant name="struts.custom.i18n.resources" value="message"></constant> -->
<package name="default" extends="struts-default">
<action name="uploadAction" class="com.action.UploadAction">
<result>/success.jsp</result>
</action>
</package>
</struts>
3、UploadAction.java
package com.action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.logging.Logger;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class UploadAction extends ActionSupport{
private File upload; //上传的文件
private String uploadName;//上传的文件名
public File getUpload() {
return upload;
}
public void setUpload(File upload) {
this.upload = upload;
}
public String getUploadName() {
return uploadName;
}
public void setUploadName(String uploadName) {
this.uploadName = uploadName;
}
public String execute() throws Exception{
InputStream is=new FileInputStream(getUpload());//获取文件的输入流
OutputStream os=new FileOutputStream("d:\\upload\\"+getUpload().getName());//指定输出流地址
byte buffer[] = new byte[1024];
int count=0;
while((count=is.read(buffer))>0){
os.write(buffer,0,count);
}
os.close();
is.close();
return SUCCESS;
}
}
4、上传的结果：文件名乱码
