Subject [jira] [Commented] (CXF-6544) OutputStream#close not called for WriterInterceptor
Date Tue, 29 Sep 2015 10:51:04 GMT

    [ https://issues.apache.org/jira/browse/CXF-6544?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14934990#comment-14934990
] 

Sergey Beryozkin commented on CXF-6544:
---------------------------------------

Yes, making sure close() is called can be easily done from AbstractClient, wrapping an abstract
doWriteBody call.
I guess HttpUrlConnection simply calls close() on its OutputStream so if we start calling
close() earlier - would that cause side-effects, i.e, would that upset somehow HTTP writes
?

But also : the headers have already been written by that time so it won't work after all,
how would you pass the digest value ?

> Hi
> close() is called later in the JAXRS client lifecycle so no way to add code properly
at this moment:
> {code}
> ClientBuilder.newBuilder()
>                 .build()
>                 .register(new WriterInterceptor() {
>                     @Override
>                     public void aroundWriteTo(final WriterInterceptorContext writerInterceptorContext)
throws IOException, WebApplicationException {
>                         writerInterceptorContext.setOutputStream(new FilterOutputStream(writerInterceptorContext.getOutputStream())
{
>                             @Override
>                             public void close() throws IOException {
>                                 // need code here
>                                 super.close();
>                             }
>                         });
>                     }
>                 })
> {code}
> Overall idea can need more work since i'd like to be able to add a final trailer to a
HTTP chunk communication.
> Managed to do it with httpclient but I'd like to stick to JAXRS 2 if possible.
