获取 java.lang.IllegalArgumentException：某些但并非所有更改 JSON 属性值的尝试的参数类型不匹配

Question

IDE：IntelliJ IdEA 2017.2.4 语言：Groovy 2.4.11 测试框架：Spock 1.1-groovy-2.4

以上所有内容的新内容。也没有 Java 方面的经验。首先 post 在这里，我实际上阅读了介绍和指南并尽力遵循。

JSON 请求：

{
  "source": "source",
  "quoteId": null,
  "quoteVersion": null,
  "quote": {
    "globalTransactionId": "k2o4-6969-1fie-poef",
    "quoteStatus": "Not Uploaded",
    "events": {
      "eventDescription": "event description",
      "eventTypeName": "Event Type"
    },
    "someReport": {
      "acceptResultsFlag": "Y",
      "orderDate": "2017-06-14",
      "orderStatus": "string"
    },
    "anotherReport": {
      "id": 627311,
      "orderDate": "2017-06-14"
    },
    "attributes": [
      {
        "appliedFlag": "Y",
        "attributeDetail": {
          "name": "attribute1",
          "value": "value1"
        },
        "attributeName": "attribute1"
      }
    ]
  }
}

当我尝试更改 quote.attributes.appliedFlag 时，我得到：

java.lang.IllegalArgumentException：com 的参数类型不匹配。serviceSpecIdeaNo2.NULL 值：验证响应代码和消息内容。(serviceSpecIdeaNo2.groovy:23)

代码：

class serviceSpecIdeaNo2 extends Specification {

    def 'NULL values: verify response codes and message content.'() {

        given: 'a JSON request with null field values'
        def url = 'http://someservice.com:1234'
        def path = '/endPoint'
        def client = new RESTClient(url)
        client.handler.failure = client.handler.success

        def inputFile  = new File('input.json')
        def json = new JsonSlurper().parse(inputFile)

        def changeValueTo = null

        def (lvl1, lvl2, lvl3, lvl4, lvl5) = data.fullPath.tokenize('.')

        if (lvl5 != null) {
            json."$lvl1"."$lvl2"."$lvl3"."$lvl4"."$lvl5" = changeValueTo
        } else if (lvl4 != null) {
            json."$lvl1"."$lvl2"."$lvl3"."$lvl4" = changeValueTo
        } else if (lvl3 != null) {
            json."$lvl1"."$lvl2"."$lvl3" = changeValueTo
        } else if (lvl2 != null) {
            json."$lvl1"."$lvl2" = changeValueTo
        } else {
            json."$lvl1" = changeValueTo
        }

        when: 'the request is submitted'
        def response = client.post([
                path              : path,
                requestContentType: JSON,
                body              : json
        ])

Answer 1

你真的应该改进你的问题，它的质量很低。它有很多错别字和错误。

在我更改了一些内容后，我能够重现您的错误。但是由于您还有很多其他问题，我不能 100% 确定它与您得到的一样。就我而言，问题是，在您的 JSON 中，您有

"attribute": [
  {
    "appliedFlag": "Y",
    "attributeDetail": {
      "name": "attra",
      "value": "value1"
    },
    "attributeName": "attra"
  }
]

这意味着 attribute 是一个列表。因此，如果您查询 record.attribute.appliedFlag，您将获得列表中条目的所有 appliedFlag 属性的列表，因此当您尝试设置它时会出现错误。
