Constructor Details

JettyWebSocketClient

public JettyWebSocketClient()

Default constructor that creates and manages an instance of a Jetty WebSocketClient.

JettyWebSocketClient

public JettyWebSocketClient(org.eclipse.jetty.websocket.client.WebSocketClient client)

Constructor that accepts an existing instance of a Jetty WebSocketClient.

Method Details

start

public void start()

Description copied from interface: Lifecycle

Start this component.

Should not throw an exception if the component is already running.

In the case of a container, this will propagate the start signal to all components that apply.

Specified by:

start in interface Lifecycle

See Also:

• SmartLifecycle.isAutoStartup()

stop

public void stop()

Description copied from interface: Lifecycle

Stop this component, typically in a synchronous fashion, such that the component is fully stopped upon return of this method. Consider implementing SmartLifecycle and its stop(Runnable) variant when asynchronous stop behavior is necessary.

Note that this stop notification is not guaranteed to come before destruction: On regular shutdown, Lifecycle beans will first receive a stop notification before the general destruction callbacks are being propagated; however, on hot refresh during a context's lifetime or on aborted refresh attempts, a given bean's destroy method will be called without any consideration of stop signals upfront.

Should not throw an exception if the component is not running (not started yet).

In the case of a container, this will propagate the stop signal to all components that apply.

Specified by:

stop in interface Lifecycle

See Also:

• SmartLifecycle.stop(Runnable)
• DisposableBean.destroy()

isRunning

public boolean isRunning()

Description copied from interface: Lifecycle

Check whether this component is currently running.

In the case of a container, this will return true only if all components that apply are currently running.

Specified by:

isRunning in interface Lifecycle

Returns:

whether the component is currently running

execute

public reactor.core.publisher.Mono<Void> execute(URI url,
 WebSocketHandler handler)

Description copied from interface: WebSocketClient

Execute a handshake request to the given url and handle the resulting WebSocket session with the given handler.

Specified by:

execute in interface WebSocketClient

Parameters:

url - the handshake url

handler - the handler of the WebSocket session

Returns:

completion Mono<Void> to indicate the outcome of the WebSocket session handling.

execute

public reactor.core.publisher.Mono<Void> execute(URI url,
 @Nullable
 HttpHeaders headers,
 WebSocketHandler handler)

Description copied from interface: WebSocketClient

A variant of WebSocketClient.execute(URI, WebSocketHandler) with custom headers.

Specified by:

execute in interface WebSocketClient

Parameters:

url - the handshake url

headers - custom headers for the handshake request

handler - the handler of the WebSocket session

Returns:

completion Mono<Void> to indicate the outcome of the WebSocket session handling.
