嗨，任何帮助都会成为我这个问题的好助手 知道为什么我的客户端调用web服务时出现此错误？ 它是在JBoss上运行的cxf客户端。当我在我的客户端IPdfUtilitiesService_BasicHttpBindingIPdfUtilitiesService_Client上调用convert方法时，我得到了SOAPFaultException：
javax.xml.ws.soap.SOAPFaultException: Cannot create an abstract class.

任何方式IPdfUtilitiesService都是客户端的接口。
这是问题。
您必须在其中一个实现类中实现此IPdfUtilitiesService接口，假设类名为serviceImpl。在此类中，您必须覆盖wsdl中的所有操作（方法）。
public class serviceImpl implements IPdfUtilitiesService{
@Override
Convert
@Override
Modify
@Override
Merge
@Override
GetFileInfo
}
我认为你忘了在这里覆盖/定义Convert方法，结果你的serviceImpl类变得抽象，因为它没有实现IPdfUtilitiesService接口的所有方法。导致上述错误。
Read this用于java中的抽象概念。
注意到实现接口的类必须实现 所有界面的方法。但是，可以定义一个 提供的类没有实现所有接口的方法 该类被声明为抽象。
