How to specify jackson to only use fields - preferably globally

Michael Wiles picture Michael Wiles · Aug 18, 2011 · Viewed 136.9k times · Source

Default jackon behaviour seems to use both properties (getters and setters) and fields to serialize and deserialize to json.

I would like to use the fields as the canonical source of serialization config and thus don't want jackson to look at properties at all.

I can do this on an individual class basis with the annotation:

 @JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)

But I don't want to have to put this on every single class...

Is it possible to configure this globally? Like add some to the Object Mapper?

You can configure individual ObjectMappers like this:

ObjectMapper mapper  = new ObjectMapper();
mapper.setVisibility(mapper.getSerializationConfig().getDefaultVisibilityChecker()
                .withFieldVisibility(JsonAutoDetect.Visibility.ANY)
                .withGetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withSetterVisibility(JsonAutoDetect.Visibility.NONE)
                .withCreatorVisibility(JsonAutoDetect.Visibility.NONE));

If you want it set globally, I usually access a configured mapper through a wrapper class.
