如何在java中将int转换为json

public class MyObject {
    private int myInt;

    public int getMyInt() {
        return myInt;
    }

    public void setMyInt(int myInt) {
        this.myInt = myInt;
    }
}

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) {
        MyObject myObject = new MyObject();
        myObject.setMyInt(123);

        ObjectMapper objectMapper = new ObjectMapper();
        try {
            String json = objectMapper.writeValueAsString(myObject);
            System.out.println(json);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

{"myInt":123}
