Java serialization using objectMapper: serialize using private getter

Question

I have a private field with a private getter method (because I hope to prevent other users from using the getter outside this class, while I have a use case for this getter within this class), but I hope the field to be serialized using objectMapper. What is a good way to do it? Would appreciate any idea!

@Data
public class TestClass{
    @Getter(AccessLevel.PRIVATE)
    private String field
}

ObjectMapper by default will serialize only public fields, but you can change it using setVisibility method. You can do it like this:

TestClass testClass = new TestClass("field");
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
objectMapper.writeValueAsString(testClass);
