For my REST api I'm using jersey and ExceptionMapper to catch global exceptions. It works well all the exception my app throws but I'm unable to catch exception thrown by jackson.
For example one of my endpoint accept an object that contains an enum. If the Json in the request has a value that is not in the enum jersey throw this exception back
Can not construct instance of my.package.MyEnum from String value 'HELLO': value not one of declared Enum instance names: [TEST, TEST2]
at [Source: org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream@5922e236; line: 3, column: 1] (through reference chain: java.util.HashSet[0]->....)
Even though I have created this mapper
@Provider
@Component
public class JacksonExceptionMapper implements ExceptionMapper<JsonMappingException> {
@Override
public Response toResponse(JsonMappingException e) {
....
}
}
The code never reach this mapper.
Is there anything we need to do in order to catch these exceptions?
EDIT Note: I have jus tried being less general and instead of JsonMappingException I use InvalidFormatException in this case the mapper is called. But I still don't understand because InvalidFormatException extends JsonMappingException and should be called as well
JacksonFeature.class
so Jersey uses Jackson. If that's the case, Jackson is registering it's own mapper. You can try registeringJacksonJaxbJsonProvider.class
instead which doesn't register it's own exception mapper. That should do the trick. – Sweetening
