Hi,
Sorry for the so late reply. We've moved the mailing list to user jboss
mailing list: http://resteasy.jboss.org/mailinglists from May 2016.
Did you try with add @Body annotation in TestData class and directly use
the annotated filed in your service ? If @Body is not a required thing
to use , can you simply try with the
latest resteasy and directly send the json request which represents the
TestData object ? I can't see why @Body is required here.
Cheers,
Jim

Oggetto: [Resteasy-users] How to use JSON message body in POST

Hello,
I'm trying to POST JSON data to a JAX-RS servlet running in WildFly
8.2.0 (RESTEasy 3.0.10). I started out coding the method like this,
because this is what I see in every example I've found with Google
(this could mean I just have poor Google skills).
@Path("/test")
@Consumes("application/json;charset=utf-8")
@Produces("application/json;charset=utf-8")
public Response execute(TestData data) {
AppResponse response = new AppResponse();
// do some stuff
return Response.status(200).entity(response).build();
}
That failed because the
factory.getInjectorFactory().createParameterExtractor(parameter,
factory) call in this constructor always returned null, which caused a
NullPointerException when the request was processed.
public MethodInjectorImpl(ResourceLocator resourceMethod,
ResteasyProviderFactory factory)
{
this.factory = factory;
this.method = resourceMethod;
this.interfaceBasedMethod =
findInterfaceBasedMethod(resourceMethod.getResourceClass().getClazz(),
resourceMethod.getMethod());
params = new ValueInjector[resourceMethod.getParams().length];
int i = 0;
for (MethodParameter parameter : resourceMethod.getParams())
{
params[i] =
factory.getInjectorFactory().createParameterExtractor(parameter, factory);
if (params[i] instanceof MessageBodyParameterInjector)
expectsBody = true;
i++;
}
}
That was happening because parameter.paramType is ParamType.UNKNOWN. A
little more debugging led me to the @Body annotation. It looks like
adding @Body to the parameter would fix the problem, but @Body is only
valid for methods and fields, not parameters. So, I changed my code to
this
@Bodyprivate TestData data;
@Path("/test")
@Consumes("application/json;charset=utf-8")
@Produces("application/json;charset=utf-8")
public Response execute() {
AppResponse response = new AppResponse();
// do some stuff
return Response.status(200).entity(response).build();
}
That "works" (my method is able to do its work and generate a
response), but at some point after my method finishes, RESTEasy pukes
and dies with this exception.
