jackson - MockServer:解析JSON时出现IllegalArgumentException

当我尝试使用MockServer模拟外部HTTP API时，mockserver返回java.lang.IllegalArgumentException
这是测试代码:

new MockServerClient("localhost", 1080)
    .when(request("/messages")
    .withMethod("POST")
    .withQueryStringParameters(
        param("subject", "integration-test-subject")
    )
).respond(response().withStatusCode(200));

这是例外:

java.lang.IllegalArgumentException: Exception while parsing
[
   {
      "httpRequest":{
         "method":"POST",
         "path":"/messages",
         "queryStringParameters":{
            "subject":[
               "integration-test-subject"
            ]
         }
      },
      "httpResponse":{
         "statusCode":200
      },
      "times":{
         "remainingTimes":0,
         "unlimited":true
      },
      "timeToLive":{
         "unlimited":true
      }
   }
] for Expectation

这是 jackson 的例外:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.String` out of FIELD_NAME token
at
[
   Source:(String)"   {
      "httpRequest":{
         "method":"POST",
         "path":"/messages",
         "queryStringParameters":{
            "subject":[
               "integration-test-subject"
            ]
         }
      },
      "httpResponse":{
         "statusCode":200
      },
      "times":{
         "remainingTimes":0,
         "unlimited":true
      },
      "timeToLive":{
         "unlimited":true
      }
   }

我正在尝试通过主体发送application/x-www-form-urlencoded请求

subject:integration-test-subject

如果在测试中不存在.withQueryStringParameters(param("subject", "integration-test-subject"))，则它正常。

如何解决这个问题？

最佳答案

这是GitHub中的问题，并有解释

您可以更新到5.4.1
