Java 使用jersey测试框架测试时收到HTTP 500错误

我实现了一个RESTWeb服务，并希望使用jUnit test测试我的实现

当我使用REST参考框架Jersey时，我想使用提供的测试框架JerseyTest，但我得到一些奇怪的行为：

如果我的资源创建了一个包含字符串的响应，那么一切都可以正常工作。请参阅测试用例响应代码404IfGetForNotExistingGuitag。 当我的响应包含pojo时，问题就会出现。请参阅测试用例响应代码200IFGETFOREXISTINGGUITAG。我没有收到预期的200响应代码，但收到500“内部服务器错误”。如果我用手测试整个界面，一切正常。所以我假设我需要以某种方式配置测试框架，但我不知道如何配置

我将实现作为模板

我使用Jersey 2.0，因为它目前正在我的glassfish 4.0上运行，没有机会更新它，Mockito作为模拟框架，Jackson作为JSON框架

我希望你们能帮助我。如果你需要更多的信息，请告诉我

可能是因为您在测试方法ResponseDeis200IfGetForExistingGuitag中使用getGuiTagMock而不是getCharGuiTagMock？是否还有其他可能有堆栈跟踪的日志？啊，我在研究了将近一天后才发现。我的构建路径中确实包含了jersey-media-moxy.jar库。即使未使用此库，也会导致错误。感谢Priyesh花时间查看我的代码，很抱歉我浪费了它。没问题。很高兴问题解决了。
