[英]Start or Stop a jetty ServerConnector without server restart
I use jetty server to handle client requests and have a requirement where I need to start or stop one or few ServerConnectors on demand without restarting the server to which these connectors are attached to.我使用 jetty 服务器来处理客户端请求,并且需要根据需要启动或停止一个或几个 ServerConnector,而无需重新启动这些连接器所连接到的服务器。
For example.例如。
ServerConnector httpConnector;
ServerConnector httpsConnector;
Server server;
server.addConnector(httpConnector);
server.addConnector(httpsConnector);
server.start()
Need to start/stop/cancel a particular connector without forcing server to restart.需要启动/停止/取消特定连接器而不强制服务器重新启动。
You would have to do the following ...您必须执行以下操作...
// TODO: Have a reference to the Connector you are going to work with
// Remove from server first.
server.removeConnector(connector);
// Stop the connector.
// NOTE: Existing connections will still live on.
// This will only stop accepting new connections.
connector.stop(); // might take a while (waiting for acceptors to close)
// TODO: do what you want with this connector
// Eg: harshly close existing connections
connector.getConnectedEndPoints().forEach((endpoint)-> {
endpoint.close();
});
// Re-add stopped connector if you want
// This will start connector as well
// This can fail (eg: if port is already in use)
server.addConnector(connector);
You can call stop
on the connector to stop it and start
to start it again.您可以在连接器上调用
stop
来停止它并start
重新启动它。 To get the relevant connector there are two solutions:要获得相关的连接器,有两种解决方案:
getConnectors
, iterate over them, find the one you want to stop and call stop
or start
on it to stop or start it.getConnectors
获取服务器的所有连接器,遍历它们,找到要停止的连接器并调用stop
或start
来停止或启动它。
