BigDecimal Json View Issues

[twiz911]

Hi

Your library does exactly what we were looking for. However, we've noticed enabling it changes our BigDecimal field JSON from:

"latitude": 9874359834.345,

to:

"latitude": { "intVal": null, "scale": 3, "precision": 13, "stringCache": null, "intCompact": 9874359834345 },

How can we restore it back to the initial version?

Thanks

The fix appears to be adding handling BigDecimal in JsonViewSerializer.writePrimitive()

Yeah, that'd be the fix. If you want to open a pull request, feel free. Otherwise I'll try to get this taken care of in the next couple weeks.

Thanks. Actually I'm not sure how to fix as now when I try to deserialize the JSON I get the error

Can not deserialize instance of java.math.BigDecimal out of START_OBJECT token

Any advice? Thanks

The problem is that you want to represent a BigDecimal as a primitive number like

{
  "myField" : 254.984
} 

The serializer is (correctly) treating BigDecimal as an object, because it is one. BigDecimal is typically used in place of double, but it doesn't have JAXB binding methods so by default it will not be deserializable which is why you get that error.

The JsonViewSerializer just needs to be updated to serialize/deserialize BigDecimal as a primitive instead of an object.

This is now available in version 0.12 in Maven Central.
