骆驼、蓝图和骆驼:奔跑

Question

我正在启动一个非常简单的骆驼蓝图项目，它在karaf（servicemix）中运行良好（或类似良好），但为了在我的机器上进行开发和调试，我想将它与骆驼maven插件集成。

我的蓝图是这样的：

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/blueprint"
       xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"
       xsi:schemaLocation="
       http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
       http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/spring/camel-blueprint.xsd">
    <cm:property-placeholder persistent-id="ru.igc.igsb" update-strategy="reload">
        <cm:default-properties>
            <cm:property name="csvPath" value="C:/files"/>
        </cm:default-properties>
    </cm:property-placeholder>
    <camelContext xmlns="http://camel.apache.org/schema/blueprint">
        <route>
            <from uri="file:{{csvPath}}"/>
            <log message="The message contains ${body}"/>
        </route>
    </camelContext>
</blueprint>

我的pom有这个：

 <plugin>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-maven-plugin</artifactId>
    <!-- optional, default value: org.apache.camel.spring.Main -->
    <configuration>
      <useBlueprint>true</useBlueprint>
    </configuration>
  </plugin>

但是骆驼：运行失败：

Answer 1

可能缺少依赖项（请参阅https://issues.apache.org/jira/browse/CAMEL-9321)。

解决方案

添加

<dependency>
    <groupId>org.apache.aries.blueprint</groupId>
    <artifactId>org.apache.aries.blueprint.core</artifactId>
</dependency>

到pom.xml的依赖项-部分（根目录，而不是/bin下的派生pom.xml）。

希望这能有所帮助。

Answer 2

我刚刚使用了ServiceMix 5.4.x中的camel示例(https://github.com/apache/servicemix/tree/servicemix-5.4.x/examples/camel/camel-blueprint)，用你的替换了现有的蓝图，并将插件添加到pom文件中

<plugin>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-maven-plugin</artifactId>
    <version>2.14.1</version>
    <!-- optional, default value: org.apache.camel.spring.Main -->
    <configuration>
      <useBlueprint>true</useBlueprint>
    </configuration>
</plugin>

它对我有效。请将您的项目（尤其是pom文件）与示例项目进行比较。请确保使用相同的camel和camel插件版本。
