Class StompClientSupport
- java.lang.Object
- org.springframework.messaging.simp.stomp.StompClientSupport
- Direct Known Subclasses:
ReactorNettyTcpStompClient,WebSocketStompClient
public abstract class StompClientSupport extends Object
Base class for STOMP client implementations.Subclasses can connect over WebSocket or TCP using any library. When creating a new connection, a subclass can create an instance of @link DefaultStompSession} which extends
TcpConnectionHandlerwhose lifecycle methods the subclass must then invoke.In effect,
TcpConnectionHandlerandTcpConnectionare the contracts that any subclass must adapt to while usingStompEncoderandStompDecoderto encode and decode STOMP messages.- Since:

public StompClientSupport()
Method Detail
setMessageConverter
public void setMessageConverter(MessageConverter messageConverter)
Set theMessageConverterto use to convert the payload of incoming and outgoing messages to and frombyte[]based on object type and the "content-type" header.By default,
SimpleMessageConverteris configured.- Parameters:
messageConverter- the message converter to use
getMessageConverter
public MessageConverter getMessageConverter()
Return the configuredMessageConverter.
setTaskScheduler
public void setTaskScheduler(@Nullable TaskScheduler taskScheduler)
Configure a scheduler to use for heartbeats and for receipt tracking.Note: Some transports have built-in support to work with heartbeats and therefore do not require a TaskScheduler. Receipts however, if needed, do require a TaskScheduler to be configured.
By default, this is not set.
getTaskScheduler
@Nullable public TaskScheduler getTaskScheduler()
The configured TaskScheduler.
setDefaultHeartbeat
public void setDefaultHeartbeat(long[] heartbeat)
Configure the default value for the "heart-beat" header of the STOMP CONNECT frame. The first number represents how often the client will write or send a heart-beat. The second is how often the server should write. A value of 0 means no heart-beats.By default this is set to "10000,10000" but subclasses may override that default and for example set it to "0,0" if they require a TaskScheduler to be configured first.
- Parameters:
heartbeat- the value for the CONNECT "heart-beat" header- See Also:
- https://stomp.github.io/stomp-specification-1.2.html#Heart-beating
getDefaultHeartbeat
public long[] getDefaultHeartbeat()
Return the configured default heart-beat value (nevernull).
isDefaultHeartbeatEnabled
public boolean isDefaultHeartbeatEnabled()
Determine whether heartbeats are enabled.Returns
falseifdefaultHeartbeatis set to "0,0", andtrueotherwise.
setReceiptTimeLimit
public void setReceiptTimeLimit(long receiptTimeLimit)
Configure the number of milliseconds before a receipt is considered expired.By default set to 15,000 (15 seconds).
getReceiptTimeLimit
public long getReceiptTimeLimit()
Return the configured receipt time limit.
createSession
protected ConnectionHandlingStompSession createSession(@Nullable StompHeaders connectHeaders, StompSessionHandler handler)
Factory method for create and configure a new session.- Parameters:
connectHeaders- headers for the STOMP CONNECT framehandler- the handler for the STOMP session- Returns:
- the created session
processConnectHeaders
protected StompHeaders processConnectHeaders(@Nullable StompHeaders connectHeaders)
Further initialize the StompHeaders, for example setting the heart-beat header if necessary.- Parameters:
connectHeaders- the headers to modify- Returns:
- the modified headers
