Apache Camel：带有CxfEndpoint的RouteBuilder

Question

你好！

我尝试使用Java DSL和RouteBuilder实现Camel路由。我想从计时器端点发送到cxf端点。

代码：

public class MyRoute extends RouteBuilder {

    @Override
    public void configure() {

        CamelContext camelContext = getContext();

        CxfEndpoint cxfEndpoint = new CxfEndpoint();
        cxfEndpoint.setAddress("http://localhost:8088/interface");
        cxfEndpoint.setWsdlURL("wsdl/contract.wsdl");
        cxfEndpoint.setCamelContext(camelContext);
        cxfEndpoint.setDataFormat(DataFormat.PAYLOAD);

        try {
            camelContext.addEndpoint("myEndpoint", cxfEndpoint);
        } catch (Exception e) {
            e.printStackTrace();
        }


        from("timer://my-timer?fixedRate=true&period=500")
                .transform(constant("DummyBody"))
                .to("cxf://myEndpoint");        
    }

}

此路由被插入到使用Spring XML定义的camel上下文中（我有一些其他路由）。

问题：

我收到以下错误：

karaf@root> Exception in thread "SpringOsgiExtenderThread-78" org.apache.camel.FailedToCreateProducerException: Failed to create Producer fo
r endpoint: Endpoint[cxf://myEndpoint]. Reason: java.lang.IllegalArgumentException: serviceClass must be specified

        at org.apache.camel.util.ServiceHelper.startService(ServiceHelper.java:62)
        ....

现在错误非常简单，但here说：

  

此选项仅在POJO模式下需要。如果是wsdlURL选项   提供，PAYLOAD和MESSAGE模式不需要serviceClass。

问题：

如果我使用PAYLOAD模式，为什么还需要服务类？我在创建cxf端点时遗漏了什么？

谢谢！

您已经设置了要使用的CxfEndpoint，因此您的路线应该就像这样

from("timer://my-timer?fixedRate=true&period=500")
                .transform(constant("DummyBody"))
                .to(myEndpoint);
