编写jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title></title>
</head>
<body>
<!--enctype="multipart/form-data"文件以二进制上传 -->
<form action="files.action" method="post" enctype="multipart/form-data">
<input name="files" type="file"><!--这里的name="files"必须和action中的属性名对应 （private File files;） -->
<input type="submit" >
</form>
</body>
</html>
编写action处里请求
package action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class filesAction {
private File files;
public File getFiles() {
return files;
}
public void setFiles(File files) {
this.files = files;
}
public String execute() throws Exception{
//输出流，并指定输出路径
FileOutputStream fos=new FileOutputStream("f:/abc.rar");
//创建输入流读取文件
FileInputStream fis=new FileInputStream(files);
//创建字节数组设置缓冲区
byte[] bytes=new byte[1024];
int len=fis.read(bytes);
//边写入边读取二进制
while(len>0){
//趁着读取字节未覆盖原来的字节前，把其写入硬盘
fos.write(bytes);
//继续读取字节直到读取完
len=fis.read();
}
fos.flush();
fos.close();
fis.close();
return "success";
}
}
Struts.xml配置文件
