java - Apache Camel : RouteBuilder with CxfEndpoint

Question

您好!

我正在尝试使用 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");        
    }

}

这条路线被插入到使用 Spring XML 定义的 Camel 上下文中(我有一些其他路线)。

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，但是 here说:

This option is only required by POJO mode. If the wsdlURL option is provided, serviceClass is not required for PAYLOAD and MESSAGE mode.

问题:

如果我使用的是 PAYLOAD 模式，为什么我还需要一个服务类？创建 cxf 端点时我是否遗漏了什么？

谢谢!

您已经设置了要使用的 CxfEndpoint，因此您的路线应该是这样的

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