osgi注册服务和servlet的两种方法

直接上代码：

public void start(BundleContext bundleContext) throws Exception {
bc = bundleContext;
registerResource();
} 


private void registerResource() {

//注册servlet
Dictionary<String, String> props = new Hashtable<String, String>();
String url = "/demo";
props.put("alias", url);
props.put("servlet-name", "Servlet_" + url);
HelloWorldServlet servlet = createHttpServlet();
bc.registerService(Servlet.class.getName(), servlet, props);

//注册资源
try {
serviceReference = bc.getServiceReference(HttpService.class
.getName());
if (serviceReference != null) {
httpService = (HttpService) bc.getService(serviceReference);
httpService.registerResources("/demo", "webroot", null);
}
} catch (Exception e) {
e.printStackTrace();
}
}
