骆驼ActiveMq蓝图
Camel ActiveMq Blueprint
我是骆驼和蓝图的新手。
我正在尝试制作一个简单的程序来将数据放入队列中。
不确定这里出了什么问题。

您的 OSGI 环境中是否安装了 camel-core？如果您在 karaf (2.x.x) 中，请输入
features:list | grep camel
如果没有显示，您可以执行以下操作：
features:chooseurl camel
添加仓库，然后:
features:install camel-core
我强烈建议您阅读 "OSGi in Action"。 ClassNotFoundException 通常表示您的上下文在 class 另一个包将导出时不可见。由于"org/apache/camel/spi/EndpointCompleter"是camel-core，你必须在你的osgi环境中安装它。
检查包是否导出:
jschoreels@lab> exports | grep camel.spi
100 org.apache.camel.spi; version="2.14.3"
jschoreels@lab> list | grep 100
START LEVEL 100 , List Threshold: 50
[ 100] [Active ] [ ] [ ] [ 50] camel-core (2.14.3)
但是，您的包也必须导入此包。你可以做一个：
imports <bundleidOfYourImportingBundle>
检查包裹是否在。
如果没有，您必须检查是否正确构建了包。一个正确的 bundle 应该在 MANIFEST.MF 中声明一些 OSGi header。 You can have an example here.
要用maven生成它，你应该考虑使用依赖bnd的maven bundle plugin。
这是一个使用它的例子：
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>${maven-bundle-pulgin.version}</version>
<configuration>
<instructions>
<Import-Package>*</Import-Package>
<Export-Package />
</instructions>
</configuration>
</plugin>
</plugins
</build>
如果你想学习 OSGi，我真的建议你 OSGi in action 并至少阅读三层（模块化、生命周期和服务）章节以了解发现的工作原理。最后解释了什么是bnd以及如何使用它。
堆栈跟踪提示您似乎 运行 模拟 OSGi 环境中的 camel 上下文。
de.kalpatec.pojosr.framework.PojoSRBundle.loadClass(PojoSRBundle.java:431)
尝试在像 karaf 这样的真实 OSGi 环境中运行它。
问题出在camel的版本上。
我在 pom.xml 中更改了 camel 版本，它工作正常
