使用 JMS 服务引用创建 Spring 上下文时出现异常
Exception when creating Spring Context with JMS Service references
我们有一个 Swing UI 客户端，它使用一个 Appclient，它使用 CAMEL bean 设置一个 Spring 框架上下文，用于通过 JMS 与 OSGi 服务器中的远程服务对话。
这是服务参考之一的示例：
<bean id="computerDataManager" class="org.apache.camel.spring.remoting.CamelProxyFactoryBean">
<property name="serviceUrl" value="jms:queue:computerDataManager"/>
<property name="serviceInterface" value="xxxx.core.api.ComputerDataInterface"/>
</bean>
最近我们向 OSGi (Karaf) 服务器添加了 'camel-http' 功能以允许使用 HTTP URI 端点。
当客户端使用以下 Stacktrace 启动时，服务器上的此包含已开始创建警告：

这似乎表明在创建我们现有的 JMS 端点时，它会以某种方式找到对 'RequestEntity' class 的引用。我们的任何代码中都没有对此 class 的引用，因此我们不确定为什么会开始出现此警告。
有什么方法可以让我们获得有关它试图实例化哪个 bean 的更多信息？
最终追踪到添加了 'camel-http' 的 Karaf 包的第三方依赖项。
我们没有 'interface' 类 单独捆绑的服务。一旦我们将它们分开并且只包含 'api' 与接口的捆绑包，错误就消失了。
