Java Gson:格式化输出 json 字符串


#Java Gson


示例

package org.example;

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

public class TestPrettyPrint {

    @Data
    public static class UserInfo {
        private String useName;
    }

    public static void main(String[] args) {
        UserInfo userInfo = new UserInfo();
        userInfo.setUseName("李白");

        Gson gson = new GsonBuilder().setPrettyPrinting().create();
        String jsonStr = gson.toJson(userInfo);
        System.out.println(jsonStr);
    }

}

执行结果:

{
  "useName": "李白"
}
