我已经在Ubuntu Linux 10.04上安装了Karaf(2.2.5)。将ActiveMQ作为Karaf之上的功能安装。创建了带有 stomp 连接器的自定义代理。现在,当我尝试从 Java 客户端连接到此 stomp 代理时,我得到"java.net.SocketTimeoutException: Read timedout"
如果我将 ActiveMQ 作为独立应用程序启动,则相同的客户端工作正常。
提前致谢
这是我的配置:

我看不出您的配置有明显的问题...就我个人而言,我已经停止在OSGi中使用Spring,因为我不断遇到启动时竞争条件。Spring 的<osgi:service>
使用超时,因此启动延迟会搞砸一切。以下替代方法在 Karaf 2.2.4 下对我来说非常有效:
- 将此存储库添加到我的etc/org.apache.karaf.features.cfg文件:
mvn:org.apache.activemq/activemq-karaf/${activemq.version}/xml/features
- 添加通过蓝图编写的 etc/activemq-broker.xml 文件。我从 Talend 的一个示例 XML 开始,并根据我的需求对其进行了自定义。
- 在我自己的功能中声明对 activemq-blueprint 的依赖.xml文件如下所示:
<feature version="${activemq.version}">activemq-blueprint</feature>
- 在我的功能中声明该 XML 文件.xml:
<bundle>blueprint:file:etc/activemq-broker.xml</bundle>
总的来说,我不是蓝图的忠实粉丝,但它使这个配置对我来说非常容易。
