FUSE（servicemix）ESB中骆驼cxf路线上的IllegalStateException

Question

我尝试在 FUSE（版本 4.3.0）ESB/OSGi 容器中设置骆驼（版本 2.4.0）路由。 将 WebService 调用从“代理”地址路由到真实服务应该是一个简单的 cxf-proxy。

我阅读了几个文档：

• CXF Proxy Example
• camel cxf component

并设置以下弹簧配置：

<?xml version="1.0" encoding="UTF-8"?>

    <import

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

    <!-- the proxy service -->
    <cxf:cxfEndpoint
        id="myServiceProxy"
        address="http://localhost:9003/cxf/myService"
        serviceClass="foo.bar.iface.MyServiceInterface" />

    <!-- my real existing cxf soap service -->
    <cxf:cxfEndpoint
        id="myService"
        address="http://foo.bar/services/myService"
        wsdlURL="http://foo.bar/services/myService?wsdl"
        serviceClass="foo.bar.iface.MyServiceInterface"
        serviceName="s:MyService"
        endpointName="s:MyServiceEndpoint"
        xmlns:s="http://foo.bar/iface/" />

    <!-- route -->
    <camel:camelContext>
        <camel:route>
            <camel:from
                uri="cxf:bean:myServiceProxy" />
            <camel:to
                uri="cxf:bean:myService" />
        </camel:route>
    </camel:camelContext>

</beans>

尝试在 FUSE 中启动捆绑包会导致此异常

karaf@root> Exception in thread "SpringOsgiExtenderThread-22" org.apache.camel.RuntimeCamelException: java.lang.IllegalStateException: Endpoint address should be a relative URI wrt to the servlet address (use '/xxx' for example)
        at org.apache.camel.util.ObjectHelper.wrapRuntimeCamelException(ObjectHelper.java:1126)
        at org.apache.camel.spring.SpringCamelContext.onApplicationEvent(SpringCamelContext.java:103)

        at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:97)

我不知道怎么了。我怀疑我的 Endpoint 地址是错误的，我不知道我的 servlet 地址是什么（没有 cxf:cxfEndoint servelt 地址属性）。

如果能帮助我找到正确的方向来解决这个问题，我们将不胜感激。

谢谢 克劳斯

Answer 1

我终于发现了问题所在。

相反

<!-- the proxy service -->
<cxf:cxfEndpoint
    id="myServiceProxy"
    address="http://localhost:9003/cxf/myService"
    serviceClass="foo.bar.iface.MyServiceInterface" />

应该是的

<!-- the proxy service -->
<cxf:cxfEndpoint
    id="myServiceProxy"
    address="/myService"
    serviceClass="foo.bar.iface.MyServiceInterface" />

由于第一种方法在 FUSE 外部运行骆驼项目效果很好（在这种情况下，将启动 http 服务器以提供服务），因此它必须是 FUSE 内部的相对地址。

在 FUSE 内部，将使用在 (localhost:8181) 上运行的嵌入式 HTTP 服务器，服务 url 将扩展为 http://localhost:8181/cxf/myService。
