如何使用Java中的Jackson库对属性的顺序进行序列化？

public @interface JsonPropertyOrder

import com.fasterxml.jackson.core.*;
import com.fasterxml.jackson.databind.*;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
import java.util.*;
import java.io.*;
public class JsonPropertyOrderTest {
   public static void main(String args[]) throws JsonGenerationException, JsonMappingException,        IOException {
      Employee emp = new Employee();
      emp.setFirstName("Adithya");
      emp.setEmpId(25);
      emp.setLastName("Jai");
      emp.getTechnologies().add("Java");
      emp.getTechnologies().add("Scala");
      emp.getTechnologies().add("Python");
      ObjectMapper mapper = new ObjectMapper();
      mapper.writerWithDefaultPrettyPrinter().writeValue(System.out, emp);
   }
}
// Employee class
@JsonPropertyOrder({
   "firstName",
   "lastName",
   "technologies",
   "empId"
})
class Employee {
   private int empId;
   private String firstName;
   private String lastName;
   private List<String> technologies = new ArrayList<>();
   public int getEmpId() {
      return empId;
   }
   public void setEmpId(int empId) {
      this.empId = empId;
   }
   public String getFirstName() {
      return firstName;
   }
   public void setFirstName(String firstName) {
      this.firstName = firstName;
   }
   public String getLastName() {
      return lastName;
   }
   public void setLastName(String lastName) {
      this.lastName = lastName;
   }
   public List<String> getTechnologies() {
      return technologies;
   }
   public void setTechnologies(List<String> technologies) {
      this.technologies = technologies;
   }
}

{
   "firstName" : "Adithya",
   "lastName" : "Jai",
   "technologies" : [ "Java", "Scala", "Python" ],
   "empId" : 125
}
