In Java, when can we call @JsonAnyGetter and @JsonAnySetter annotations?

@JsonAnyGetter Comments Allows the use of a Map as a container for the properties we want to serialize to JSON and @JsonAnySetter annotation instructs Jackson to call the same setter method on all unrecognized fields in the JSON object, which means all fields that are not mapped to properties or setter methods in the Java object.

Syntax

public @interface JsonAnyGetter

Example

import java.io.*;
import java.util.*;
import com.fasterxml.jackson.core.*;
import com.fasterxml.jackson.databind.*;
import com.fasterxml.jackson.annotation.*;
public class JsonAnyGetterAndJsonAnySetterTest {
   public static void main(String args[]) throws JsonGenerationException, JsonMappingException, IOException {
      Employee emp1 = new Employee();
      emp1.setFirstName("Adithya");
      emp1.setLastName("Sai");
      emp1.setEmpId(125);
      emp1.getAdditionalInformation().put("technology1", "Machine Learning");
      emp1.getAdditionalInformation().put("technology2", "Robotics");
      ObjectMapper mapper = new ObjectMapper();
      String jsonStr = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(emp1);
      System.out.println(jsonStr);
      System.out.println("Deserializing JSON to Object:");
      Employee emp2 = mapper.readValue(jsonStr, Employee.class);
      System.out.println("id : " + emp2.getEmpId());
      System.out.println("firstName : " + emp2.getFirstName());
      System.out.println("lastName : " + emp2.getLastName());
      System.out.println("Additional information : " + emp2.getAdditionalInformation());
   }
}
// Employee class
