如何通过Java中的多部分表单数据上载时如何知道文件数

Question

I am trying to upload multiple files using multipart form-data in java and I am using play framework.

Http.MultipartFormData body = request().body().asMultipartFormData(); files=body.getFiles();

But I may have more than 1 file and I need to know the count of files in body.

I got the file count using a for loop.

But Is there a better way to get the file count without using a loop.

Answer 1

Http.MultipartFormData body = request().body().asMultipartFormData();
List<Http.MultipartFormData.FilePart> files = body.getFiles();
int fileCount = files.size();

Here fileCount will give you number of files you have.
