使用Java解析json并打印key和vaules

import com.google.gson.JsonElement;
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;

public class JsonParsingExample {
    public static void main(String[] args) {
        String json = "{\"key1\":\"value1\",\"key2\":\"value2\",\"key3\":\"value3\"}";

        // 使用JsonParser解析JSON字符串
        JsonElement jsonElement = JsonParser.parseString(json);
        JsonObject jsonObject = jsonElement.getAsJsonObject();

        // 遍历JSON对象的键值对并打印
        for (String key : jsonObject.keySet()) {
            String value = jsonObject.get(key).getAsString();
            System.out.println("Key: " + key + ", Value: " + value);
        }
    }
}

Key: key1, Value: value1
Key: key2, Value: value2
Key: key3, Value: value3
