karaf功能包和karaf包之间的部署差异:安装

Question

下面两种部署有何不同

<feature name="my-base-bundles" version="${project.version}">
        <bundle start-level="86">mvn:com.my.osgi/mycomponent/0.0.1</bundle>
</feature>

和

bundle:install -s mvn:com.my.osgi/mycomponent/0.0.1

我观察到的是使用功能显示服务进行部署：

[com.my.osgi.mycomponent]
-----------------------------------------------------
instance.name = mycomponent.3c2c91a5-4c28-46c3-a08e-1470192ef353
 service.bundleid = 76
 service.factoryPid = com.my.osgi.mycomponent
 service.id = 397
 service.pid = com.my.osgi.mycomponent.3c2c91a5-4c28-46c3-a08e-1470192ef353
 service.scope = bundle

通过使用包进行部署:安装

[org.apache.felix.ipojo.Factory]
--------------------------------
 component.class = com.my.osgi.mycomponent
 component.description = factory name="com.my.osgi.mycomponent" bundle="77" state="valid" implementation-class="com.my.osgi.mycomponent"
        requiredhandlers list="[org.apache.felix.ipojo:properties, org.apache.felix.ipojo:callback, org.apache.felix.ipojo:provides, org.apache.felix.ipojo:architect
ure]"
        missinghandlers list="[]"
        provides specification="com.my.osgi.mycomponent"
        inherited interfaces="[com.my.osgi.mycomponent]" superclasses="[]"
 component.providedServiceSpecifications = [com.my.osgi.mycomponent]
 factory.name = com.my.osgi.mycomponent
 factory.state = 1
 service.bundleid = 77
 service.id = 153
 service.pid = com.my.osgi.mycomponent
 service.scope = singleton

它工作得很好，但我的pax-test测试失败了，因为在安装后，我寻找服务

serviceReferences = this.bundleContext.getServiceReferences("com.my.osgi.mycomponent", filter);

我应该如何在pax-exam中部署，这样我才能访问功能部署等服务？

Answer 1

两个安装的启动级别不同。

• 功能安装: start level = 86
• 捆绑安装: start level = defaut = 90 defaut

因此，尝试使用某个起始级别的值来安装包
