How can I tell jackson to ignore a property for which I don't have control over the source code?
Long story short, one of my entities has a GeometryCollection that throws an exception when you call "getBoundary" (the why of this is another book, for now let's say this is the way it works).
Is there a way I can tell Jackson not to include that specific getter? I know I can use @JacksonIgnore when I do own/control the code. But this is not case, jackson ends reaching this point through continuous serialization of the parent objects. I saw a filtering option in jackson documentation. Is that a plausible solution?
Thanks!
Solution 1:
You can use Jackson Mixins. For example:
class YourClass {
public int ignoreThis() { return 0; }
}
With this Mixin
abstract class MixIn {
@JsonIgnore abstract int ignoreThis(); // we don't need it!
}
With this:
objectMapper.getSerializationConfig().addMixInAnnotations(YourClass.class, MixIn.class);
Edit:
Thanks to the comments, with Jackson 2.5+, the API has changed and should be called with objectMapper.addMixIn(Class<?> target, Class<?> mixinSource)
Solution 2:
One other possibility is, if you want to ignore all unknown properties, you can configure the mapper as follows:
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
