java - 可用方法的 NoSuchMethodException

Question

我正在为我的应用程序使用 Open KM 应用程序框架。奇怪的是，有时我的代码中出现可用方法的 NoSuchMethodException。一旦我开始收到此异常，它就会一直重复，直到我重新启动服务器 (Jboss7)。一旦重新启动，这将工作文件直到某个点，然后再次发生此异常并继续发生。

有人可以帮忙吗？

我的异常跟踪

我还放置了一些其他跟踪信息，以了解调用类和预期方法是什么。这些是结果

19:34:10,719 INFO  [stdout] (http--192.168.1.62-8080-2) Trying to fetch method ========      create from class : interface com.openkm.ws.client.document.OKMDocument

19:34:10,719 INFO  [stdout] (http--192.168.1.62-8080-2) The parameters for the expected method are

19:34:10,719 INFO  [stdout] (http--192.168.1.62-8080-2) >>>>>>>>>.... [B

这是调用方法端点类的 getMethods 的结果

19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2)  Method Name :: create
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters.... java.lang.String
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters....  com.openkm.ws.client.document.Document
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters.... [B

我们可以看到调用签名是

create(String, com.openkm.ws.client.document.Document, byteArray)

目标类也有一个具有相同签名的方法，但有时我仍然会收到此 NoSucnMethodException 并且如前所述，一旦它出现，它就会一直出现，直到我重新启动服务器。

任何帮助...

com.openkm.ws.client.document.Document 是一个接口(interface)。我怀疑运行时部署中缺少实现。
