Boon - @JsonInclude
@JsonInclude is used to include properties having null/empty or default values. By default Boon ignore such properties during serialization/de-serialization.
Example - @JsonInclude
Following example is for @JsonInclude −
import org.boon.json.JsonFactory; import org.boon.json.ObjectMapper; import org.boon.json.annotations.JsonInclude; public class BoonTester { public static void main(String args[]) { ObjectMapper mapper = JsonFactory.createUseAnnotations( true ); Student student = new Student(1,null); String jsonString = mapper.writeValueAsString(student); System.out.println(jsonString); } } class Student { public int id; @JsonInclude public String name; Student(int id, String name) { this.id = id; this.name = name; } }
Output
When the script runs successfully, you will see the following output −
{"id":1,"name":null}
