Question

我正在为我的应用程序使用Open KM应用程序框架。很奇怪看到我的代码中有时会得到NoSuchMethodException以获得可用的方法。一旦我开始得到这个异常，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，直到某一点，然后再次发生此异常并继续发生。

有人可以帮忙吗？

我的例外追踪

我已经提出了一些其他的痕迹以了解什么是调用类和预期的方法..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) >>>>>>>>>.... [B

这是来自调用方法端点类

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

我们可以看到呼叫签名是

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

并且目标类也有一个具有相同签名的方法，但有时我仍然会得到这个NoSucnMethodException，并且一旦它出现，它就会一直存在，直到我重新启动服务器。

任何帮助......

Answer 1

com.openkm.ws.client.document.Document是一个界面。我怀疑运行时部署中缺少实现。

可用方法的NoSuchMethodException
