Method Detail

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)
                           throws BeansException

Specified by:

setApplicationContext in interface ApplicationContextAware

Throws:

BeansException

setBeanName

public void setBeanName(String beanName)

Specified by:

setBeanName in interface BeanNameAware

setApplicationEventPublisher

public void setApplicationEventPublisher(ApplicationEventPublisher applicationEventPublisher)

Specified by:

setApplicationEventPublisher in interface ApplicationEventPublisherAware

setChannelResolver

public void setChannelResolver(DestinationResolver<MessageChannel> channelResolver)

Set the handler's channel resolver.

Parameters:

channelResolver - the channel resolver to set.

setOutputChannel

public void setOutputChannel(MessageChannel outputChannel)

Set the handler's output channel.

Parameters:

outputChannel - the output channel to set.

setOutputChannelName

public void setOutputChannelName(String outputChannelName)

Set the handler's output channel name.

Parameters:

outputChannelName - the output channel bean name to set.

Since:

5.1.4

setOrder

public void setOrder(Integer order)

Set the order in which the handler will be subscribed to its channel (when subscribable).

Parameters:

order - the order to set.

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
                    throws BeansException

Specified by:

setBeanFactory in interface BeanFactoryAware

Throws:

BeansException

getBeanFactory

protected BeanFactory getBeanFactory()

setAdviceChain

public void setAdviceChain(List<Advice> adviceChain)

Set the advice chain to be configured within an AbstractReplyProducingMessageHandler to advise just this local endpoint. For other handlers, the advice chain is applied around the handler itself.

Parameters:

adviceChain - the adviceChain to set.

setAsync

public void setAsync(Boolean async)

Currently only exposed on the service activator namespace. It's not clear that other endpoints would benefit from async support, but any subclass of AbstractReplyProducingMessageHandler can potentially return a ListenableFuture<?>.

Parameters:

async - the async to set.

Since:

4.3

setComponentName

public void setComponentName(String componentName)

Sets the name of the handler component.

Parameters:

componentName - The component name.

getObject

public H getObject()

Specified by:

getObject in interface FactoryBean<MessageHandler>

createHandlerInternal

protected final H createHandlerInternal()

createHandler

protected abstract H createHandler()

getObjectType

public Class<? extends MessageHandler> getObjectType()

Specified by:

getObjectType in interface FactoryBean<MessageHandler>

getPreCreationHandlerType

protected Class<? extends MessageHandler> getPreCreationHandlerType()

Subclasses can override this to return a more specific type before handler creation. After handler creation, the actual type is used.

Returns:

the type.

isSingleton

public boolean isSingleton()

Specified by:

isSingleton in interface FactoryBean<MessageHandler>
