野蝇上的骆驼 cxf

Question

我已经创建了一个 SOAP 网络服务，我想在 wildfly 上使用 camel-cxf 公开它。

当我想部署它时，出现以下错误：

Apache CXF library (cxf-core-3.2.0.jar) detected in ws endpoint deployment; either provide a proper deployment replacing embedded libraries with container module dependencies or disable the webservices subsystem for the current deployment adding a proper jboss-deployment-structure.xml descriptor to it. The former approach is recommended, as the latter approach causes most of the webservices Java EE and any JBossWS specific functionality to be disabled.

尝试了建议的方法，但没有奏效。试图从我的 pom.xml:

中包含的 caml-cxf 中排除 cxf 依赖项

<dependency>
   <groupId>org.apache.camel</groupId>
   <artifactId>camel-cxf</artifactId>
   <version>2.20.0</version>
   <exclusions>
     <exclusion>
         <groupId>org.apache.cxf</groupId>
          <artifactId>*</artifactId>
     </exclusion>
   </exclusions>
</dependency>

解决了错误但产生了新错误：

Failed to define class org.apache.camel.component.cxf.spring.AbstractCxfBeanDefinitionParser in Module "deployment.CamelCXF-1.0.war" from Service Module Loader: java.lang.NoClassDefFoundError: Failed to link org/apache/camel/component/cxf/spring/AbstractCxfBeanDefinitionParser

你能帮我解决这些错误或提供一个我可以在 wildfly 上部署和扩展的小示例吗？非常感激。

在我的 pom.xml 中定义了这些依赖项：

<dependencies>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-core</artifactId>
        <version>2.20.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-cxf</artifactId>
        <version>2.20.0</version>
        <exclusions>
            <exclusion>
                <groupId>org.apache.cxf</groupId>
                <artifactId>*</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>5.0.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>

    </dependency>
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>8.0</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

这是我的 camel.xml:

    </route>
</camel:camelContext>

后续问题

我可以使用@Tadayoshi Sato 提供的链接设置网络服务。然而，这些示例仅使用一个处理器的一个简单函数。当我在端口定义中有多个操作时，我如何知道调用了哪个函数？是否可以让骆驼调用所提供接口的实现，或者我必须自己映射它？

正如 Claus 所指出的，在 WildFly 上使用 Camel 的最推荐方法是使用 WildFly Camel。您可以在下面的 link 中找到如何将 WildFly Camel 子系统安装到 WildFly：
http://wildfly-extras.github.io/wildfly-camel/index.html

安装 WildFly Camel 后，让我们看看这个 link，您可以在其中找到如何在 WildFly 上使用 camel-cxf 开发代码：
http://wildfly-extras.github.io/wildfly-camel/index.html#_jax_ws

重点是WildFly已经有自己的CXF库作为一个子系统，你需要尽可能使用内置的库；否则，您可能会遇到问题中的尴尬问题。 WildFly Camel 子系统让您可以为您的 Camel 应用程序使用底层的 WildFly 子系统。

更新：

对于 camel-cxf 消费者，调用的操作名称可通过 CxfConstants.OPERATION_NAME 消息头获得。根据：
https://github.com/apache/camel/blob/master/components/camel-cxf/src/main/docs/cxf-component.adoc

The camel-cxf endpoint consumer POJO data format is based on the CXF invoker, so the message header has a property with the name of CxfConstants.OPERATION_NAME and the message body is a list of the SEI method parameters.

您可以 route a message based on this message header 并相应地更改实现。
