如何在 Servlet 上检索字符串作为 Multipart Post 的一部分发送

Question

This may be very simple question but I have been looking around for a while. I am sending two strings to a Java Servlet on Tomcat 7.

multipartContent.addPart("destadd", sb1);
multipartContent.addPart("destfilename", sb2);

I am trying to retrieve these String like this

String destFileName = request.getPart("destfilename").getName();

but in vein. I will appreciate any help.

Answer 1

I was running around for two days almost, fianlly I got the answer

Part destFileNamePart = request.getPart("destfilename");
Scanner s = new Scanner(destFileNamePart.getInputStream());
String destFileName = s.nextLine();

Answer 2

有点晚了，但可能对其他人有帮助：

IOUtils.toString( destFileNamePart.getInputStream() );

Answer 3

Have you looked at Get form parameters from multipart request without getting the files .

You can also use utility class such as O'Reilly MultipartRequest and more info here
