Java 使用动态ID从json获取详细信息的Jolt规范

Given dynamic accountId return the onlineId and signinId for that specific user.

输入JSON:

[
  {
    "request": {
      "body": {
        "inputAccountId": "1234"
      }
    }
  },
  {
    "accountId": "1234",
    "ageGroup": 3,
    "role": 1,
    "gender": "f",
    "signinId": "aa@aa.com",
    "onlineId": "one"
  },
  {
    "accountId": "1122",
    "ageGroup": 3,
    "role": 2,
    "gender": "f",
    "signinId": "bb@aa.com",
    "onlineId": "two"
  },
  {
    "accountId": "2211",
    "ageGroup": 1,
    "role": 1,
    "gender": "f",
    "signinId": "cc@aa.com",
    "onlineId": "three"
  }
]

根据用例，如果accountId=1234或accountId可以是任何帐户1122或2211，则返回该帐户ID的输出JSON.

-Jolt，来吧.

[
  {
    "operation": "modify-overwrite-beta",
    "spec": {
      "request": {
        "inputAccountId": "@(3,request.body.inputAccountId)"
      }
    }
  },
  {
    "operation": "shift",
    "spec": {
      "request": {
        "inputAccountId": "requestedId"
      },
      "1": {
        "*": {
          "accountId": {
            "requestedId": {
              "onlineId": "onlineId",
              "signinId": "signInId"
            }
          }
        }
      }
    }
  }
]

我无法使上面的代码正常工作.Java抛出错误- 读取jolt Spec文件时抛出"java.lang.NullPointerException".

我还try 了${qustedId}，但它是数字的，所以我将其添加为请求ID，这会抛出nullPointer异常.
