无法实例化[org.apache.cxf.jaxws.spring.EndpointDefinitionParser $ SpringEndpointImpl]。找不到默认构造函数

Question

最近我必须升级CXF 2.7 to CXF 3.1.2。我们使用的spring版本是Spring 4.1.8。

尝试在以下行中创建EndPointImpl对象时发生错误：

 EndpointImpl myWSImpl = (EndpointImpl)Boot.getAppContext().getBean("myWebService");

请注意，我无法升级到Spring 4.2，因此我必须在context.file中注释掉这些行，以便cxf 3.1使用Spring 4.1

<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

我尝试过以下操作：

Bus bus = (Bus)  Boot.getAppContext().getBean(Bus.DEFAULT_BUS_ID);
Object implementor = Boot.getAppContext().getBean("myWebService");
EndpointImpl myWSImpl = new EndpointImpl(bus, implementor);

但我仍然遇到同样的错误，我在日志中发现了以下错误：

我还可以做些什么来消除此错误。

感谢。
