JsonInclude annotaion for associated class

Question

By using @JsonInclude(JsonInclude.Include.NON_EMPTY) at class level it ignores null and empty value tags during serialization.

Is there any variant of JsonInclude or any other library or class where we can ignore null and empty properties of associated (has-a) class.

Answer 1

You have the option to do with annotation at the class level, ie:

 @JsonInclude(Include.NON_NULL) //or Include.NON_EMPTY, if that fits your use case public static class Request { // ... }

As noted in comments, in versions below 2.x the syntax for this annotation is:

 @JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL) // or JsonSerialize.Inclusion.NON_EMPTY

The other option is to configure the ObjectMapper directly, simply by calling mapper.setSerializationInclusion(Include.NON_NULL);
