Example 2: java serialize object to json

public class someClass {
//your lcode and logic...
ObjectMapper mapper = new ObjectMapper();
SimpleModule module = new SimpleModule();
module.addSerializer(MyAwesomeClass.class, new MyAwesomeSerializer());
mapper.registerModule(module);

jsonNode = mapper.convertValue(myAwesomeObject, JsonNode.class);
//... your code and logic
}
  
public class MyAwesomeSerializer extends StdSerializer<MyAwesomeClass> {

    public MyAwesomeSerializer() {
        super(MyAwesomeClass.class);
    }

    @Override
    public void serialize(MyAwesomeClass myAwesomeClass, JsonGenerator jgen, SerializerProvider provider) throws IOException {
        ObjectMapper mapper = new ObjectMapper();

        jgen.writeStartObject();
        jgen.writeStringField("name", myAwesomeClass.getName());
        jgen.writeStringField("age", myAwesomeClass.getAge());

          jgen.writeArrayFieldStart("hobbies");
          for (Hobby hobby : myAwesomeClass.getHobbies()) {
              jgen.writeObject(mapper.convertValue(hobby, JsonNode.class));
          }
          jgen.writeEndArray();
      
        jgen.writeEndObject();
    }
