從JSONPath中數組的不同對象中查詢具有特定值的鍵

Question

{
  "dataObject": [
    {
      "id": 263626,
      "role": {
        "id": 12054,
        "name": "Edit",
        "description": ""
      },
      "resource": {
        "id": 5756,
        "type": "resource"
      }
    },
    {
      "id": 263364,
      "role": {
        "id": 12054,
        "name": "Edit",
        "description": ""
      },
      "resource": {
        "id": 5728,
        "type": "resource"
      }
    }
  ]
}

我有一個看起來像這樣的JSON對象。 我需要從dataObject提取json對象，其name:Edit和id： 5756 。 如何使用JSON路徑實現此目的？ 嘗試$..[?(@.name="Edit", @.id=5756)]無效。

Java代碼：

JsonPath.parse(json).read("$..[?(@.name='Edit'), (@.id=5756)]")

嘗試使用父對象名稱和邏輯運算符AND 。 結果路徑將是

$..[?((@.resource.id == 5756) && (@.role.name == 'Edit'))] 。

在com.jayway.jsonpath:json-path:2.4.0單元測試中，這對我com.jayway.jsonpath:json-path:2.4.0

@Test
public void testParse() {
    String json = "{\n" +
            "  \"dataObject\": [\n" +
            "    {\n" +
            "      \"id\": 263626,\n" +
            "      \"role\": {\n" +
            "        \"id\": 12054,\n" +
            "        \"name\": \"Edit\",\n" +
            "        \"description\": \"\"\n" +
            "      },\n" +
            "      \"resource\": {\n" +
            "        \"id\": 5756,\n" +
            "        \"type\": \"resource\"\n" +
            "      }\n" +
            "    },\n" +
            "    {\n" +
            "      \"id\": 263364,\n" +
            "      \"role\": {\n" +
            "        \"id\": 12054,\n" +
            "        \"name\": \"Edit\",\n" +
            "        \"description\": \"\"\n" +
            "      },\n" +
            "      \"resource\": {\n" +
            "        \"id\": 5728,\n" +
            "        \"type\": \"resource\"\n" +
            "      }\n" +
            "    }\n" +
            "  ]\n" +
            "}";

    DocumentContext parse = JsonPath.parse(json);
    Object read = parse.read("$..[?((@.resource.id == 5756) && (@.role.name == 'Edit'))]");
    assertNotNull(read);
}
