播放Java 2框架，返回分块响应

Question

Based on the following code example that returns chunked data from Play server, the out.write shouldn't create response each time it is called? when using post client I get only 1 response which contains that wholl data with all the data.

I need to return a huge file from the server in chunks which should be downloaded in the client. Any ideas?

public static Result index(){ 
// Prepare a chunked text stream 
Chunks<String> chunks = new StringChunks() 
{ 
    // Called when the stream is ready 
    public void onReady(Chunks.Out<String> out) 
    { 
        out.write("kiki");
        out.write("foo");
        out.write("bar");
        out.close();
     }
 };// Serves this stream with 200 OK 
return ok(chunks); 
}

The amount of chunks depends on the chunk size, which usually defaults to 1024 KB throughout the framework. Your output is too small and thus only one chunk is sent.
