Question

在我的应用程序中，我有2个捆绑包。两者都使用cxf来创建Restful服务器。在那些捆绑包中，我通过蓝图加载cxf。我在那些具有相同id 的捆绑包上定义cxf：bus，以期望两个捆绑包将共享同一个总线实例，然后我可以在一个捆绑包上配置身份验证拦截器，它也将申请另一个捆绑包。他们看起来像下面。

捆绑1：

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
       xmlns:cxf="http://cxf.apache.org/blueprint/core"
       xsi:schemaLocation="
         http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
         http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
         http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd
         ">
<bean id="authInterceptor" class="com.dasannetworks.vn.rest.impl.AuthInterceptorImpl"></bean>
<cxf:bus id="my-app-bus" name="tutorial">
   <cxf:inInterceptors>
        <ref component-id="authInterceptor"/>
    </cxf:inInterceptors>
</cxf:bus>


<bean id="Rest1ServiceImpl"class="com.dasannetworks.vn.rest.impl.Rest1ServiceImpl"></bean>

<bean id="jsonProvider" class="org.apache.cxf.jaxrs.provider.json.JSONProvider">
    <property name="serializeAsArray" value="true"/>
    <property name="dropRootElement" value="true"/>
    <property name="supportUnwrapped" value="true"/>
</bean>

<jaxrs:server id="custom1Service" address="/rest1">
    <jaxrs:serviceBeans>
        <ref component-id="rest1ServiceImpl"/>
    </jaxrs:serviceBeans>
    <jaxrs:providers>
        <ref component-id="jsonProvider"/>
    </jaxrs:providers>
</jaxrs:server>

捆绑2：

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
       xmlns:cxf="http://cxf.apache.org/blueprint/core"
       xsi:schemaLocation="
         http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd
         http://cxf.apache.org/blueprint/jaxrs http://cxf.apache.org/schemas/blueprint/jaxrs.xsd
         http://cxf.apache.org/blueprint/core http://cxf.apache.org/schemas/blueprint/core.xsd
         ">

<cxf:bus id="my-app-bus" bus="tutorial"></cxf:bus>
<bean id="rest2Service" class="com.dasannetworks.vn.rest2.impl.Rest2ServiceImpl" />
<jaxrs:server id="custom2Service" address="/rest2">
    <jaxrs:serviceBeans>
        <ref component-id="rest2Service"/>
    </jaxrs:serviceBeans>

安装并运行后：结果：对“/ cxf / rest1 /”的所有休止请求都将运行到authInterceptor中，而对“cxf / rest2”的所有休止请求都不会。

有人可以给我一些关于如何在两个捆绑包上共享同一个cxf：bus的建议吗？先感谢您。

由于我无法用蓝图解决这个问题，我改变了修复它的方法。我使用Activator启动了CXF Bus Rest服务器而不是蓝图。

捆绑1活化剂： 在bundle 1中，我获取默认总线并在其上添加身份验证拦截器，然后在其上注册Rest Server端点。

public void start(BundleContext bundleContext) throws Exception {
    Bus defaultBus = BusFactory.getDefaultBus();
    defaultBus.setId("my-app-bus");
    BusFactory.clearDefaultBusForAnyThread(defaultBus);
    System.out.println(this.getClass().getName());
    System.out.println(defaultBus.getId());
    defaultBus.getInInterceptors().clear();
    defaultBus.getInInterceptors().add(new AuthInterceptorImpl());

    JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
    sf.setBus(defaultBus);
    sf.setAddress("/tutorial");
    sf.setServiceClass(HelloRestServiceImpl.class);
    sf.create();
}

在捆绑2中， 捆绑2激活器 我得到默认总线，注册并为Rest Server设置该总线。

@Override
public void start(BundleContext bundleContext) throws Exception {
    Bus defaultBus = BusFactory.getDefaultBus();
    List<Interceptor<? extends Message>> inInterceptors = defaultBus.getInInterceptors();
    for(Interceptor interceptor: inInterceptors) {
        System.out.println( interceptor.getClass().getName());
    }

    JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
    sf.setBus(defaultBus);
    sf.setAddress("/Rest2");
    sf.setServiceClass(Rest2ServiceImpl.class);
    sf.create();
}

==＆GT;结果：两个bundle现在使用相同的总线，bundle 2可以运行到我在bundle 1上注册的身份验证拦截器。 !!!

如何在karaf上的多个osgi包上共享cxf：bus？
