我有这个 json 字符串：

我想提取在 number: "0", "1", "2"... 等节点之后的所有 id。

我已经通过使用 jsonpath: 成功获得了一个 id：$.response.data.0.id并得到了"15124". 但我正在寻找一个 jsonpath，它将提取 Json 字符串中的所有 id。换句话说，这是扩展输出：15124, 13498, 14296, 13364, 14060, 13672.

这是我拥有的 Json 字符串：

GSON 库是将 java 对象转换为 json 字符串的好选择，反之亦然。

这是使用 [Gson#fromJson()] 将 JSON 字符串转换为 java Map 的示例代码。

查找更多示例...

示例代码：

BufferedReader reader = new BufferedReader(new FileReader(new File("resources/json.txt")));
Gson gson = new Gson();
Type type = new TypeToken<Map<String, Map<String, Object>>>() {}.getType();
Map<String, Map<String, Object>> map = gson.fromJson(reader, type);

Map<String, Map<String, Object>> innerMap = (Map<String, Map<String, Object>>) map.get("response").get("data");
for (String key : innerMap.keySet()) {
    System.out.println("key:" + key + " id:" + innerMap.get(key).get("id"));
}

输出：

key:0 id:15124
key:1 id:13498
key:2 id:14296
key:3 id:13364
key:4 id:14060
key:5 id:13672

感谢 Syam S. 的回答。

$.response.data.*.id确实有效！
