Json編碼的關聯數組（來自PHP）在Java中轉換為json對象

Question

我有一個json編碼的關聯數組，其中包含map和list的組合，這是在PHP中完成的。

該json字符串通過Web服務調用傳輸到Java

我如何處理此json字符串以獲取原始的關聯數組數據。 我知道Java不支持關聯數組。 但是任何替代方案都值得贊賞。

樣本json字符串：

使用javax.jason

try (JsonReader jsonReader = Json.createReader(new StringReader(jsonString))) {
    JsonObject object = jsonReader.readObject();
    System.out.println(object);
}
