DelayerEndpointSpec

protected DelayerEndpointSpec()

DelayerEndpointSpec

protected DelayerEndpointSpec(DelayHandler delayHandler)

Method Details

defaultDelay

public DelayerEndpointSpec defaultDelay(long defaultDelay)

Parameters:

defaultDelay - the defaultDelay.

Returns:

the endpoint spec.

See Also:

• DelayHandler.setDefaultDelay(long)

ignoreExpressionFailures

public DelayerEndpointSpec ignoreExpressionFailures(boolean ignoreExpressionFailures)

Parameters:

ignoreExpressionFailures - the ignoreExpressionFailures.

Returns:

the endpoint spec.

See Also:

• DelayHandler.setIgnoreExpressionFailures(boolean)

messageStore

public DelayerEndpointSpec messageStore(MessageGroupStore messageStore)

Parameters:

messageStore - the message store.

Returns:

the endpoint spec.

delayedAdvice

public DelayerEndpointSpec delayedAdvice(Advice... advice)

Configure a list of Advice objects that will be applied, in nested order, when delayed messages are sent.

Parameters:

advice - the advice chain.

Returns:

the endpoint spec.

delayExpression

public DelayerEndpointSpec delayExpression(String delayExpression)

delayExpression

public DelayerEndpointSpec delayExpression(Expression delayExpression)

delayedMessageErrorChannel

public DelayerEndpointSpec delayedMessageErrorChannel(MessageChannel channel)

Set a message channel to which an ErrorMessage will be sent if sending the released message fails. If the error flow returns normally, the release is complete. If the error flow throws an exception, the release will be re-attempted. If there is a transaction advice on the release task, the error flow is called within the transaction.

Parameters:

channel - the channel.

Returns:

the endpoint spec.

Since:

5.0.8

See Also:

• maxAttempts(int)
• retryDelay(long)

delayedMessageErrorChannel

public DelayerEndpointSpec delayedMessageErrorChannel(String channel)

Set a message channel name to which an ErrorMessage will be sent if sending the released message fails. If the error flow returns normally, the release is complete. If the error flow throws an exception, the release will be re-attempted. If there is a transaction advice on the release task, the error flow is called within the transaction.

Parameters:

channel - the channel name.

Returns:

the endpoint spec.

Since:

5.0.8

See Also:

• maxAttempts(int)
• retryDelay(long)

maxAttempts

public DelayerEndpointSpec maxAttempts(int maxAttempts)

Set the maximum number of release attempts for when message release fails. Default 5.

Parameters:

maxAttempts - the max attempts.

Returns:

the endpoint spec.

Since:

5.0.8

See Also:

• retryDelay(long)

retryDelay

public DelayerEndpointSpec retryDelay(long retryDelay)

Set an additional delay to apply when retrying after a release failure. Default 1000L.

Parameters:

retryDelay - the retry delay.

Returns:

the endpoint spec.

Since:

5.0.8

See Also:

• maxAttempts(int)

transactionalRelease

public DelayerEndpointSpec transactionalRelease()

Specify a TransactionInterceptor Advice with default TransactionManager and DefaultTransactionAttribute for the MessageHandler.

Returns:

the spec.

Since:

5.0.8

transactionalRelease

public DelayerEndpointSpec transactionalRelease(TransactionInterceptor transactionInterceptor)

Specify a TransactionInterceptor Advice for the MessageHandler.

Parameters:

transactionInterceptor - the TransactionInterceptor to use.

Returns:

the spec.

Since:

5.0.8

See Also:

• TransactionInterceptorBuilder

transactionalRelease

public DelayerEndpointSpec transactionalRelease(TransactionManager transactionManager)

Specify a TransactionInterceptor Advice with the provided TransactionManager and default DefaultTransactionAttribute for the MessageHandler.

Parameters:

transactionManager - the TransactionManager to use.

Returns:

the spec.

Since:

5.2.5

delayFunction

public <P> DelayerEndpointSpec delayFunction(Function<Message<P>,Object> delayFunction)

Specify the function to determine delay value against Message. Typically used with a Java 8 Lambda expression:

 
  .<Foo>delay("delayer", m -> m.getPayload().getDate(),
            c -> c.advice(this.delayedAdvice).messageStore(this.messageStore()))
 
 

Type Parameters:

P - the payload type.

Parameters:

delayFunction - the Function to determine delay.

Returns:

the endpoint spec.

messageGroupId

public DelayerEndpointSpec messageGroupId(String messageGroupId)

Set a group id to manage delayed messages by this handler. Required.

Parameters:

messageGroupId - the group id for delayed messages.

Returns:

the endpoint spec.

Since:

6.2
