rcp 中使用osgi的事件通信

osgi的通信代码

 

 

发布事件

BundleContext ctx = FrameworkUtil.getBundle(this.getClass())

.getBundleContext();

ServiceReference<EventAdmin> ref = ctx.getServiceReference(EventAdmin.class);

EventAdmin eventAdmin = ctx.getService(ref);

Map<String, Object> properties = new HashMap<String, Object>();

properties.put("DATA", new Date());

Event event = new Event("viewcommunication/syncEvent", properties);

eventAdmin.sendEvent(event);

event = new Event("viewcommunication/asyncEvent", properties);

eventAdmin.postEvent(event);

 

 

 

监听（订阅）事件

EventHandler handler = new EventHandler() {

public void handleEvent(final Event event) {

Date  date=(Date) event.getProperty("DATA");

System.out.println("dfdfdfdf"+date);

}

};

Dictionary<String, String> properties = new Hashtable<String, String>();

properties.put(EventConstants.EVENT_TOPIC, "viewcommunication/*");

ctx.registerService(EventHandler.class, handler, properties);

 

在rcp中使用这种方式需要注意的就是：

 org.eclipse.osgi.services;bundle-version="3.3.0",

 org.eclipse.equinox.event;bundle-version="1.2.100"

这两个插件必须依赖

其中 org.eclipse.equinox.event 必须为自动加载
