我正在关注Servlet中的文件上传教程
我的系统配置是
Eclipse
Apache Tomcat 8.5
Jdk：1.8
我的index.html（表单代码）是
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="UploadFileServlet" method="post">
Select a file to upload
<input type="file" value="file" name="source"/>
<input type="submit" value="Upload"/>
</form>
</body>
</html>
UploadFileServlet.java
package com.upload;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.nio.file.Paths;
import java.util.Iterator;
import java.util.List;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.Part;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
/**
* Servlet implementation class UploadFileServlet
*/
@WebServlet("/UploadFileServlet")
public class UploadFileServlet extends HttpServlet
{
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
try
{
ServletFileUpload sf=new ServletFileUpload(new DiskFileItemFactory());
List<FileItem> multFileItems=sf.parseRequest(request);
System.out.println(multFileItems.isEmpty());
for(FileItem item:multFileItems)
{
item.write(new File("E:\\aman\\"+item.getName()));
}
}
catch(Exception e)
{
System.out.println(e);
}
}//End of doPost method
}
我不明白为什么它不起作用。
它不会产生任何异常。
预期输出
我希望此代码将我在表单中选择的文件上传到e：\ aman \文件夹中，但不会上传任何文件
