我有一个Tapestry web应用程序，它为一些数据集提供了完整的CRUD功能。到目前为止，我一直在使用mock来开发和测试它
然而，我现在需要用OSGi服务（与Felix一起运行）来替换mock。
我的主要问题是：
- 我需要将OSGi服务注入到我的挂毯应用程序中吗？如果需要，该怎么做
- 假设它是注入的，有没有关于如何使用它的实践？我应该用什么特殊的方式来调用这些方法或类似的东西
- 在调用了我需要的方法后，我需要对它做些什么吗？还是自动完成
- 我需要担心
HttpService吗（我看了一些关于它的抱怨，但不太明白）
为了给你提供一些上下文，我现在是这样做的
public class MyPage {
...
@Inject
private MyDao dao;
...
@Property
private List<Entry> entries;
...
void onPrepareForRender() {
...
this.entries = this.dao.getAll()
...
}
...
}
我想用一个提供相同功能的OSGi服务来代替MyDao dao，这样我就可以在onPrepareForRender方法中使用它了。
我可以放心地假设，与该服务相关联的OSGi捆绑包已经在运行。
应用程序的其余部分是作为OSGi应用程序制作的。我在pom.xml中添加/更改了一些内容（maven bundle插件，按照中的说明添加了一些清单条目http://www.javabeat.net/2011/11/writing-an-osgi-web-application/)。
然而，它仍然不起作用。
顺便说一句，我正试图将我的WAR转换为WAB。
提前感谢：）
编辑：从WAR转换和部署到WAB时出现问题
当我将我的网络应用程序打包为war时，它运行良好。然而，当我将其打包为bundle，并尝试在GlassFish中部署它时，我会收到以下错误消息：
部署期间出错：没有安装容器能够处理这个应用程序管理战争。请参阅server.log了解更多详细信息。
当我转到server.log时，上面写着：

我对OSGI不太熟悉，但您需要在AppModule中使用build*方法来提供DAO。在下面的例子中，我假设OsgiBundle是访问OSGI服务的一种方式，我不知道实际的OSGI类叫什么。
例如：
public class MyAppModule {
public void contributeApplicationDefaults(MappedConfiguration<String, String> config) {
config.add("osgi.path", "path/to/osgi.xml");
}
public OsgiBundle buildOsgiBundle(@Symbol("osgi.path") String osgiPath) {
// lookup the OSGI bundle somehow
}
public MyDao buildMyDao(OsgiBundle osgiBundle) {
return osgiBundle.getService(MyDao.class);
}
public SomeOtherDao buildSomeOtherDao(OsgiBundle osgiBundle) {
return osgiBundle.getService(SomeOtherDao.class);
}
}
如果您想要更深入的集成（即自动将所有OSGI服务发布为Tapestry IOC服务），请查看TapestrySpringFilter，它将所有springbean发布为Tapeistry IOC服务。
