Hi guys, I'm confused as to the recommended approach to deserializing non-standard JSON types. In my case there's a Long embedded in the JSON tree but I want to deserialize it to a JPA entity (based on using the Long as an id into the database)
I have looked a variety of documentation, none seem very appealing. Here is my thought process: 1. The current Exception I get is "JsonMappingException: Can not construct instance of ..., problem: no suitable creator method found". I guess I could add a constructor to my JPA entity that takes a Long , but I'd rather not have the entity itself accessing the EntityManager. I'd rather have an external DTO. 2. I can put @JsonSerialize on my JPA entity, and point it to a serializer class. But again I'd rather not tie my entity to its DTO. 3. I can use @Provider and a custom MessageBodyReader, but this appears to want to read the entire HTTP message, not just part of the JSON tree? 4. I can register a custom Jackson serializer as explained here http://wiki.fasterxml.com/JacksonHowToCustomSerializers. But to do that I'll need a custom ObjectMapper provider as explained here http://jersey.576304.n2.nabble.com/Customizing-ObjectMapper-td6234597.html And I'm very unsure what my 'new SimpleModule' should look like? Can anyone help with a 'best practice' recommendation?
