How to create Class level Array and dynamic generate JSON using Jackson API
package com.test.rest;
import java.lang.reflect.Array;

import com.bean.Employee;
import com.bean.Student;

public ObjectMapper mapper;
public String jsonString;
/*
* This method will Used to Convert ClassObject to JSON and
* return as a form of JSON as a String
*/
public String ConvetObjectArrayToJSON(Object [] array){
mapper = new ObjectMapper();
String jsonArray=null;
System.out.println(array[i]);
try{
for(int i=0;i<array.length;i++){
System.out.println(array[i].getClass());
jsonString = mapper.writeValueAsString(array[i]);
jsonString = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(array[i]);
System.out.println(array[i].getClass()+"=="+jsonString);
}
}catch(Exception e){
e.printStackTrace();
}
return jsonArray;
}
public static void main(String []args){
Student student=new Student();
student.setStudentname("Anand");
student.setStudentPlace("Bangalore");
student.setStudentResult("Ok");
Employee emp= new Employee();
emp.setEmployeeName("Antrish");
emp.setEmployeeLocation("Chennai");
emp.setEmployeeResult("Capgimini");
Animal animal=new Animal();
animal.setAnimalName("Dog");
animal.setAnimalPlace("Mumbai");
animal.setAnimalResult("Eat");
Object[] object=new Object[]{student,emp,animal};
JsonUtility jsonutility=new JsonUtility();
jsonutility.ConvertObjecttoJSOn(emp);
jsonutility.ConvetObjectArrayToJSON(object);
}
}
======================
POJO Classes are
Employee.java
private String employeeName;
private String employeeLocation;
private String employeeResult;
//Setters and Getters
Student.java
private String studentname;
private String studentPlace;
private String studentResult;
//Setters and Getters
private String animalName;
private String animalPlace;
private String animalResult;
// Setters and Getters
=======Output ====
com.bean.Student@17550481
class com.bean.Student
class com.bean.Student=={
"studentname" : "Anand",
"studentPlace" : "Bangalore",
"studentResult" : "Ok"
}
class com.bean.Employee
class com.bean.Employee=={
"employeeName" : "Antrish",
"employeeLocation" : "Chennai",
"employeeResult" : "Capgimini"
}
class com.bean.Animal
class com.bean.Animal=={
"animalName" : "Dog",
"animalPlace" : "Mumbai",
"animalResult" : "Eat"
}
