Jackson: Property can be raw, arbitrary object or POJO
Let's say I use Jackson to serialize and deserialize POJOs. I have a number of classes like this:
class Foo {
String field1;
Bar field2;
// ...
Baz baz;
}
Where baz is a large JSON object that I receive from an external system. I want to use Foo in three different ways:
- Serialize
Fooand includebazwithout even bothering to parse it, as if I had declared it as@JsonRawValue String baz. - Pretty-print
Fooand includebazjust like I received it except pretty-printed, as if I had declared it asMap<String, Object> baz. - Pass
Footo my business logic, withbazdeserialized to a POJO, as in the code above.
One way to do this would be to declare three classes, with the baz field declared in three different ways. I could also combine 2) and 3) into a single class with @JsonAnySetter and @JsonAnyGetter to capture any properties I don't recognize.
But is there a clean way to support all the three use cases above while declaring just a single Foo class?
