我想使用Event Admin Handlers

我正在尝试运行以下代码:

import org.apache.felix.ipojo.handlers.event.Publishes;
import org.apache.felix.ipojo.handlers.event.Subscriber;
import org.apache.felix.ipojo.handlers.event.publisher.Publisher;
...
@Component(immediate = true, publicFactory = false)
@Provides(specifications = {Test.class})
@Instantiate
public class Test {
...
    @Publishes(name = "myPublisher", topics = "foo")
    private Publisher m_publisher;
...
    @Subscriber(name = "mySubscriber", topics = "foo")
    public void receive(Event pEvent) {
    ...
    }
}

但是有错误:

! instances
...
Instance test.Test-0 -> invalid
...

! instance test.Test-0
gogo: NullPointerException: null

据我了解,无法获取 Publisher 组件的实例。我有活动的“Apache Felix iPOJO 事件管理处理程序 (1.8.0)”捆绑包。

利用:

  • 阿帕奇菲利克斯 4.2.1
  • org.apache.felix.ipojo.annotations (1.11.0)
  • org.apache.felix.ipojo.api (1.11.0)
  • org.apache.felix.ipojo.handler.eventadmin (1.8.0)

怎么了?谢谢。


这是捆绑列表:

首先,收集实例架构时发生的 NPE 是一个错误。您能否在https://issues.apache.org/jira/browse/FELIX上提出问题

然后,您似乎没有部署事件管理员。您可以从http://felix.apache.org/downloads.cgi下载它。
