JAX-RS receives an object as a JAXB object and as a String

Question

I have a JAX-RS web service (using knitwear) that takes a JAXB object as a request object. When we get an error, we want to register the original xml string that was sent to us. I am currently simply reconfiguring the JAXB object, but since there are several java enumerations in these classes, enumeration values ​​that are incorrectly written in the xml source string are lost, which is not acceptable for our purposes.

Does anyone know a way to get a query object both a string and a JABX object? I would rather not write my own MessageBodyReader, and I would prefer not to try and not get MessageBodyReader for JAXB, if possible. You can also use jersey specific classes. We are using version 1.0.x.

Turns out it's not that hard with the JAX-RS API. Here is what I did:

@Path("/transactions") public class TestResource<X> { private Class<X> jaxbClass; @POST @Path("/{transaction-id}") @Consumes("application/xml") public Response processPost(@Context Providers providers, @Context HttpHeaders httpHeaders, @PathParam("transaction-id") final long transactionId, final String xmlString) throws WebApplicationException, IOException { MessageBodyReader<X> reader = providers.getMessageBodyReader(jaxbClass, null, null, MediaType.APPLICATION_XML_TYPE); InputStream entityStream = new ByteArrayInputStream(xmlString.getBytes()); final X xmlObject = reader.readFrom(jaxbClass, null, null, MediaType.APPLICATION_XML_TYPE, httpHeaders.getRequestHeaders(), entityStream); //insert logic here return Response.ok().build(); } } 

This will give you xml as a string and as a JAXB object in just a few lines of code.

As an idea, you can add a servlet filter for your web application that will intercept all requests and capture the payload in the context of the stream, where it can be retrieved later if necessary.
