Package nl.vpro.jackson2.rs

Class JsonIdAdderBodyReader

java.lang.Object

nl.vpro.jackson2.rs.JsonIdAdderBodyReader

All Implemented Interfaces:

jakarta.ws.rs.ext.MessageBodyReader<Object>

@Provider
@Consumes("application/json")
@Priority(4999)
public class JsonIdAdderBodyReader
extends Object
implements jakarta.ws.rs.ext.MessageBodyReader<Object>

Sometimes jackson/resteasy will not unmarshal a json because there is no type information, but the prototype actually specifies it fully. This message body reader will deal with that (using TypeIdResolver.idFromBaseType(), by adding the id implicitly (if it is missing) before the actual unmarshal.

2.7
