如何从代码中启动和使用Apache Felix？
我无法从代码中找到有关启动和使用 Apache Felix的信息。
我想做一些我能够（或无法））与Apache Felix的Shell一起做的事情。
例如，如何启动模块？
请帮忙。
因此，经过大量时间的尝试，这是一个可能的解决方案 。
我们将有两个项目：
- OsgiModuleA ，包含一个待启动的模块
- OsgiUsage ，将使用“模块A”
项目OsgiModuleA
文件模块/ a / Activator.java
package module.a; import org.osgi.framework.*; public class Activator implements BundleActivator, ServiceListener { @Override public void start(BundleContext bc) throws Exception { System.out.println("*** started"); bc.addServiceListener(this); } @Override public void stop(BundleContext bc) throws Exception { bc.removeServiceListener(this); System.out.println("*** stopped"); } @Override public void serviceChanged(ServiceEvent se) { String s; switch (se.getType()) { case ServiceEvent.MODIFIED: s = "modified"; break; case ServiceEvent.REGISTERED: s = "registered"; break; case ServiceEvent.UNREGISTERING: s = "unregistered"; break; default: s = "unknown"; } System.out.println("= = = service changed: " + s); } } 文件manifest.mf

文件用法/ Main.java
