我无法让我的骆驼路线在 OSGI(Equinox)-Bundle 和插件项目中工作。
路线看起来像：
public class Example2Routes extends RouteBuilder {
@Override
public void configure() throws Exception {
this.from("cxf:http://localhost:8080/exampleWS?wsdlURL=META-INF/exampleWS.wsdl&dataFormat=PAYLOAD").to("stream:out");
}
}
我的测试类应该启动骆驼上下文：
public class Test {
public static void run() throws Exception {
DefaultCamelContext camelContext = new DefaultCamelContext();
camelContext.addRoutes(new Example2Routes());
camelContext.start();
}
}
该包在 Eclipse 中使用 OSGI Framework Run 配置启动。
安慰：

但是现在如何“启动” CamelContext？没有 osgi，作为标准的 java 应用程序，这个例子可以工作；但是我有一个主要方法，其中包含骆驼上下文。
我尝试了一个激活器来启动骆驼上下文：
public class Activator implements BundleActivator {
@Override
public void start(BundleContext arg0) throws Exception {
Test.run();
}
}
但这导致了像这样的错误
Failed to resolve endpoint: cxf://http://localhost:8081/exampleWS?dataFormat=PAYLOAD&wsdlURL=META-INF%2FexampleWS.wsdl due to: No component found with scheme: cxf
虽然控制台说：
20:13:04.319 DEBUG org.apache.camel.impl.osgi.Activator:97 Bundle started: org.apache.ws.xmlschema.core
20:13:04.319 DEBUG org.apache.camel.impl.osgi.Activator:97 Bundle started: org.apache.cxf.bundle

20:13:04.319 DEBUG org.apache.camel.impl.osgi.Activator:128 Found entry: META-INF/services/org/apache/camel/component/cxfrs in bundle org.apache.camel.camel-cxf
可能是因为在启动所有需要的包/组件之前调用了 run 方法，所以 Activator 中的 Test.run() 出现问题？但是如何启动骆驼上下文呢？
更新 1
更改为 OsgiDefaultCamelContext。做了一些进口。现在我得到：
The bundle "org.apache.httpcomponents.httpclient_4.2.0 [119]" could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.http; version="4.2.0"
&
The bundle "CamelOSGIExample_1.0.0.qualifier [120]" could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.http.nio.conn; version="4.0.0.beta3"
但是找不到这个包。。
更新 2：
原因
java.lang.ClassNotFoundException: org.apache.http.nio.conn.ClientAsyncConnectionManager
我下载了 httpasyncclient-osgi-4.0-beta3.jar并将org.apache.http.nio.conn添加到导入中。
在那之后我遇到了问题，以前的捆绑包需要例如org.apache.http.client或org.apache.http.auth。因此，我下载了包含所需类的httpclient-osgi-4.2.1.jar和httpclient-osgi-4.2.2.jar（因为 4.2.1 版本需要一些导入，4.2.2 需要一些导入）。但是尽管将此捆绑包添加到午餐配置中，我还是得到了
org.osgi.framework.BundleException: Exception in siServer.Activator.start() of bundle CamleOSGIExample.

Root exception:

...
Caused by: java.lang.ClassNotFoundException: org.apache.http.nio.conn.ClientAsyncConnectionManager
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:513)
我不明白这个异常，因为我将org.apache.http.nio.conn添加到导入中。
搜索需要org.apache.http.nio.conn的包，发现 cxf-2.7.3.jar。但我认为使用骆驼的 cfx 组件我也需要这个捆绑包..
