Package org.springframework.integration.websocket

Class IntegrationWebSocketContainer

java.lang.Object

org.springframework.integration.websocket.IntegrationWebSocketContainer

All Implemented Interfaces:

DisposableBean

Direct Known Subclasses:

ClientWebSocketContainer, ServerWebSocketContainer

public abstract class IntegrationWebSocketContainer
extends Object
implements DisposableBean

The high-level 'connection factory pattern' contract over low-level Web-Socket configuration.

Provides the composition for the internal WebSocketHandler implementation, which is used with native Web-Socket containers.

Collects established WebSocketSessions, which can be accessed using getSession(String).

Can accept the WebSocketListener to delegate WebSocketSession events from the internal IntegrationWebSocketContainer.IntegrationWebSocketHandler.

Supported sub-protocols can be configured, but SubProtocolCapable.getSubProtocols() have a precedent.

4.1

Constructor Details

IntegrationWebSocketContainer

public IntegrationWebSocketContainer()

Method Details

setSendTimeLimit

public void setSendTimeLimit(int sendTimeLimit)

setSendBufferSizeLimit

public void setSendBufferSizeLimit(int sendBufferSizeLimit)

setSendBufferOverflowStrategy

public void setSendBufferOverflowStrategy(@Nullable
 ConcurrentWebSocketSessionDecorator.OverflowStrategy overflowStrategy)

Set the send buffer overflow strategy.

Concurrently generated outbound messages are buffered if sending is slow. This strategy determines the behavior when the buffer has reached the limit configured with setSendBufferSizeLimit(int).

Parameters:

overflowStrategy - The ConcurrentWebSocketSessionDecorator.OverflowStrategy to use.

Since:

5.5.19

setMessageListener

public void setMessageListener(WebSocketListener messageListener)

setSupportedProtocols

public void setSupportedProtocols(String... protocols)

addSupportedProtocols

public void addSupportedProtocols(String... protocols)

setWebSocketHandler

protected void setWebSocketHandler(WebSocketHandler handler)

Replace the default WebSocketHandler with the one provided here, e.g. via decoration factories.

Parameters:

handler - the actual WebSocketHandler to replace.

Since:

5.5.18
