protected ConsumerEndpointSpec(H messageHandler)

Method Detail

phase

public S phase(int phase)

Specified by:

phase in class EndpointSpec<S extends ConsumerEndpointSpec<S,H>,ConsumerEndpointFactoryBean,H extends MessageHandler>

Parameters:

phase - the phase.

Returns:

the endpoint spec.

SmartLifecycle

autoStartup

public S autoStartup(boolean autoStartup)

Specified by:

autoStartup in class EndpointSpec<S extends ConsumerEndpointSpec<S,H>,ConsumerEndpointFactoryBean,H extends MessageHandler>

Parameters:

autoStartup - the autoStartup.

Returns:

the endpoint spec

See Also:

SmartLifecycle

poller

public S poller(PollerMetadata pollerMetadata)

Specified by:

poller in class EndpointSpec<S extends ConsumerEndpointSpec<S,H>,ConsumerEndpointFactoryBean,H extends MessageHandler>

Parameters:

pollerMetadata - the pollerMetadata

Returns:

the endpoint spec.

See Also:

AbstractPollingEndpoint

role

public S role(String role)

Description copied from class: EndpointSpec

Specify the role for the endpoint. Such endpoints can be started/stopped as a group.

Specified by:

role in class EndpointSpec<S extends ConsumerEndpointSpec<S,H>,ConsumerEndpointFactoryBean,H extends MessageHandler>

Parameters:

role - the role for this endpoint.

Returns:

the endpoint spec

See Also:

SmartLifecycle, SmartLifecycleRoleController

taskScheduler

public S taskScheduler(TaskScheduler taskScheduler)

Configure a TaskScheduler for scheduling tasks, for example in the Polling Consumer. By default the global ThreadPoolTaskScheduler bean is used. This configuration is useful when there are requirements to dedicate particular threads for polling task, for example.

Parameters:

taskScheduler - the TaskScheduler to use.

Returns:

the endpoint spec.

See Also:

IntegrationContextUtils.getTaskScheduler(org.springframework.beans.factory.BeanFactory)

handleMessageAdvice

public S handleMessageAdvice(MethodInterceptor... interceptors)

Configure a list of MethodInterceptor objects to be applied, in nested order, to the endpoint's handler. The advice objects are applied to the handleMessage() method and therefore to the whole sub-flow afterwards.

Parameters:

interceptors - the advice chain.

Returns:

the endpoint spec.

Since:

5.3

advice

public S advice(Advice... advice)

Configure a list of Advice objects to be applied, in nested order, to the endpoint's handler. The advice objects are applied only to the handler.

Parameters:

advice - the advice chain.

Returns:

the endpoint spec.

transactional

public S transactional(TransactionManager transactionManager)

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

Parameters:

transactionManager - the TransactionManager to use.

Returns:

the spec.

transactional

public S transactional(TransactionManager transactionManager,
                       boolean handleMessageAdvice)

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

Parameters:

transactionManager - the TransactionManager to use.

handleMessageAdvice - the flag to indicate the target Advice type: false - regular TransactionInterceptor; true - TransactionHandleMessageAdvice extension.

Returns:

the spec.

transactional

public S transactional(TransactionInterceptor transactionInterceptor)

Specify a TransactionInterceptor Advice for the MessageHandler.

Parameters:

transactionInterceptor - the TransactionInterceptor to use.

Returns:

the spec.

See Also:

TransactionInterceptorBuilder

transactional

public S transactional()

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

Returns:

the spec.

transactional

public S transactional(boolean handleMessageAdvice)

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

Parameters:

handleMessageAdvice - the flag to indicate the target Advice type: false - regular TransactionInterceptor; true - TransactionHandleMessageAdvice extension.

Returns:

the spec.

customizeMonoReply

public S customizeMonoReply(java.util.function.BiFunction<Message<?>,reactor.core.publisher.Mono<?>,org.reactivestreams.Publisher<?>> replyCustomizer)

Specify a BiFunction for customizing Mono replies via ReactiveRequestHandlerAdvice.

Parameters:

replyCustomizer - the BiFunction to propagate into ReactiveRequestHandlerAdvice.

Returns:

the spec.

Since:

5.3

See Also:

ReactiveRequestHandlerAdvice

requiresReply

public S requiresReply(boolean requiresReply)

Parameters:

requiresReply - the requiresReply.

Returns:

the endpoint spec.

See Also:

AbstractReplyProducingMessageHandler.setRequiresReply(boolean)

sendTimeout

public S sendTimeout(long sendTimeout)

Parameters:

sendTimeout - the send timeout.

Returns:

the endpoint spec.

See Also:

AbstractMessageProducingHandler.setSendTimeout(long)

order

public S order(int order)

Parameters:

order - the order.

Returns:

the endpoint spec.

See Also:

MessageHandlerSupport.setOrder(int)

async

public S async(boolean async)

Allow async replies. If the handler reply is a org.springframework.util.concurrent.ListenableFuture, send the output when it is satisfied rather than sending the future as the result. Ignored for handler return types other than ListenableFuture.

Parameters:

async - true to allow.

Returns:

the endpoint spec.

See Also:

AbstractMessageProducingHandler.setAsync(boolean)

notPropagatedHeaders

public S notPropagatedHeaders(String... headerPatterns)

Set header patterns ("xxx*", "*xxx", "*xxx*" or "xxx*yyy") that will NOT be copied from the inbound message. At least one pattern as "*" means do not copy headers at all.

Parameters:

headerPatterns - the headers to not propagate from the inbound message.

Returns:

the endpoint spec.

See Also:

AbstractMessageProducingHandler.setNotPropagatedHeaders(String...)

doGet

protected reactor.util.function.Tuple2<ConsumerEndpointFactoryBean,H> doGet()

Overrides:
