We can disable jackson annotations using disable() function of ObjectMapper.
Example – Disabling Annotation
import java.io.IOException; import com.fasterxml.jackson.annotation.JsonIgnoreType; import com.fasterxml.jackson.databind.MapperFeature; import com.fasterxml.jackson.databind.ObjectMapper; public class JacksonTester { public static void main(String args[]){ ObjectMapper mapper = new ObjectMapper(); try{ Student student = new Student(1,11,"1ab","Mark"); String jsonString = mapper .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); ObjectMapper mapper1 = new ObjectMapper(); mapper1.disable(MapperFeature.USE_ANNOTATIONS); jsonString = mapper1 .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } catch (IOException e) { e.printStackTrace(); } } } class Student { public int id; public String systemId; public int rollNo; public Name nameObj; Student(int id, int rollNo, String systemId, String name){ this.id = id; this.systemId = systemId; this.rollNo = rollNo; nameObj = new Name(name); } } @JsonIgnoreType class Name { public String name; Name(String name){ this.name = name; } }
Output
{ "id" : 1, "systemId" : "1ab", "rollNo" : 11 } { "id" : 1, "systemId" : "1ab", "rollNo" : 11, "nameObj" : { "name" : "Mark" } }
