class Pojo {
    String s;
    Object o;
    Map m;
}

And at runtime, I want de

I think @JsonSerialize and @JsonDeserialize is what you need. These annotations give you control on the serialization/deserialization of particular fields. This question shows elegant way to combine them into one annotation.

UPD. For this complex scenario you could take a look at BeanSerializerModifier/BeanDeserializerModifier classes. The idea is to modify general BeanSerializer/BeanDeserializer with your custom logic for particular fields and let basic implementation to do other stuff. Will post an example some time later.

UPD2. As I see, one of the way could be to use changeProperties method and assign your own serializer.

UPD3. Updated with working example of custom serializer. Deserialization could be done in similar way.

UPD4. Updated example with full custom serialization/deserialization. (I have used jakson-mapper-asl-1.9.8)

  public class TestBeanSerializationModifiers {

    static final String PropertyName = "customProperty";
    static final String CustomValue = "customValue";
    static final String BaseValue = "baseValue";

    // Custom serialization

    static class CustomSerializer extends JsonSerializer
