I've created a sample project that shows two problems I have with
RESTEasy interceptors:
A) Somehow neither the MessageBodyReaderInterceptor nor the
PreProcessInterceptor triggers. I really can't figure out why.
The MessageBodyReaderInterceptor triggers when the called method is a
plain String: post(String formValues). It doesn't trigger if the
argument is a MultivaluedMap: post(MultivaluedMap<String,String>
formValues. I believe issue is related:
https://issues.jboss.org/browse/RESTEASY-568
The PreProcessInterceptor does trigger, I only used it wrong. When
AcceptedByMethod.accept() returns true all methods are covered by the
interceptor. I've updated the example project to reflect this.
Also, I've added a MessageBodyWriterInterceptor. It does not have the
same problems as the MessageBodyReaderInterceptor.
B) I have an ExceptionMapper that works great for @Get requests. When
an exception is thrown for a @Post request, though, I get a
org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not
find MessageBodyWriter for response object of type:
no.synth.resteasyinterceptordemo.MyExceptionMapper$Error of media
type: application/x-www-form-urlencoded
This is still a problem, I have no solution here.
Are these known defects, or am I doing something very stupid? I'd be
grateful if someone would like to take a look.
The project is located at
https://github.com/henrik242/resteasy-interceptor-demo and I've tried
using Tomcat 6 and 7.
I just pushed some updates to this project, with more tests and
additional help text.
