在线查看,我发现创建套接字的方法是使用@WebSocket注释创建一个类,并使用所需的带注释的事件方法.为了使用这个套接字,使用套接字处理程序,如下所示:
import org.eclipse.jetty.websocket.server.WebSocketHandler;
import org.eclipse.jetty.websocket.servlet.WebSocketServletFactory;
import rsvp.RSVPSocket;
public class RSVPWebSocketHandler extends WebSocketHandler
{
@Override
public void configure ( WebSocketServletFactory factory )
{
factory.register( MySocket.class );
}
}
我的问题是:如果“MySocket”类有一个带参数的构造函数,我怎样才能让工厂正确调用那个?
解决方法:
您可以从servlet创建套接字.例如:
@WebServlet(name = "MyWebSocketServlet", urlPatterns = {"/myurl"})
public class MyWebSocketServlet extends WebSocketServlet {
private final static int IDLE_TIME = 60 * 1000;
@Override
public void configure(WebSocketServletFactory factory) {
factory.getPolicy().setIdleTimeout(IDLE_TIME);
factory.setCreator(new CustomWebSocketCreator());
}
}
和CustomWebSocketCreator:
public class CustomWebSocketCreator implements WebSocketCreator {
@Override
public Object createWebSocket(ServletUpgradeRequest req, ServletUpgradeResponse resp) {
return new MySocket();
}
}
