Java Jackson writeAsString转换

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) {
        // 创建一个Java对象
        Person person = new Person("John", 25);

        // 创建ObjectMapper对象
        ObjectMapper objectMapper = new ObjectMapper();

        try {
            // 将Java对象转换为JSON字符串
            String jsonString = objectMapper.writeValueAsString(person);
            System.out.println(jsonString);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    // 省略getter和setter方法
}
