java - Apache ServiceMix 7，ScalaDSL，未找到方案 : jetty 的组件

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 bundle 时，该 bundle 将解析但无法启动。当我检查日志时，我收到消息:未找到带有方案的组件:jetty

对这个问题的彻底搜索只会产生涉及确保camel-jetty包含在pom.xml中的答案。

我已经这样做了，但不幸的是它仍然不起作用..

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，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，并且作为测试，我在xml中创建了一个蓝图路线，它也使用了jetty路线并且工作正常。

关于为什么 ServiceMix/Karaf/Camel 一直坚持找不到 jetty:html: 有什么帮助吗？

非常感谢!

Answer 1

我们遇到了与此类似的问题，这是由 Camel 版本和 Jetty 版本无法协同工作的问题引起的。 Camel 尚未更新为可与 Jetty 9 配合使用，仅可与 Jetty 8 配合使用。

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，就像我们的案例一样。

有关版本控制的更多信息，请参阅 http://servicemix.apache.org/community/releases-schedule.html

编辑:Camel 2.18 将修复这些问题，但 Service Mix 7 仅使用 2.16
