Apache ServiceMix 7，ScalaDSL，未找到具有方案的组件：jetty

Question

我使用 Scala 创建了一个非常基本的包，用于 Camel 和 Karaf。当我在 Apache ServiceMix 7.0.0 / Karaf 中安装我的捆绑包时，该捆绑包将解析但不会启动。当我检查日志时，我收到消息：没有找到方案的组件：jetty

彻底搜索此问题只会得到有关确保 pom.xml.

中包含 camel-jetty 的答案

我已经这样做了，但不幸的是它仍然无法正常工作..

我的 Pom 依赖项是（除其他外）：

    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-jetty-common</artifactId>
      <version>2.16.3</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-jetty9</artifactId>
      <version>2.16.3</version>
    </dependency>
    <dependency>
      <groupId>org.apache.camel</groupId>
      <artifactId>camel-jetty</artifactId>
      <version>2.16.3</version>
    </dependency>

Scala 中的代码非常基础：

   val netStart = "jetty:http://localhost:8882/userdata"
   val netEnd = "file:scala/netoutput"

   netStart ==> {
    as (classOf[Person])
    to (netEnd)
   }

最后在 Karaf Web 控制台中显示的引用组件列表是

我已经安装了 camel-jetty9 功能，作为测试，我在 xml 中创建了一条蓝图路线，它也使用码头路线并且工作正常。

关于为什么 ServiceMix / Karaf / Camel 一直坚持找不到的任何帮助 jetty:html:?

非常感谢！

Answer 1

我们遇到了类似的问题，这是由 Camel 版本和 Jetty 版本无法协同工作引起的。 Camel 尚未更新为可与 Jetty 9 一起使用，仅可与 Jetty 8 一起使用。

如果您回滚到 Service Mix 6。1.x 那么您可能会发现问题会自行解决，就像我们的情况一样。

有关版本控制的详细信息，请参阅 http://servicemix.apache.org/community/releases-schedule.html

编辑：Camel 2.18 将解决这些问题，但 Service Mix 7 仅使用 2.16
