使用gson获取原始格式的Java json (仅用引号将字符串括起来

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

public class Main {
    public static void main(String[] args) {
        // 创建Java对象
        Person person = new Person("John", "Doe", 30);

        // 配置gson
        Gson gson = new GsonBuilder().setPrettyPrinting().create();

        // 转换为JSON字符串
        String json = gson.toJson(person);

        System.out.println(json);
    }
}

class Person {
    private String firstName;
    private String lastName;
    private int age;

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

    // 省略getter和setter方法
}

{
  "firstName": "John",
  "lastName": "Doe",
  "age": 30
}

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

public class Main {
    public static void main(String[] args) {
        // 创建Java对象
        Person person = new Person("John", "Doe", 30);

        // 配置gson
        Gson gson = new GsonBuilder().setPrettyPrinting().disableHtmlEscaping().create();

        // 转换为JSON字符串
        String json = gson.toJson(person);

        System.out.println(json);
    }
}

class Person {
    private String firstName;
    private String lastName;
    private int age;

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

    // 省略getter和setter方法
}

{
  "firstName": "John",
  "lastName": "Doe",
  "age": 30
}
