Enables annotation support for Message Endpoints. Defines the ApplicationEventMulticaster to use for this ApplicationContext. The "task-executor" reference is optional. If not provided, an instance of ThreadPoolTaskExecutor will be created by default. Defines a Point-to-Point MessageChannel. Defines a queue for messages. If 'capacity' is specified, it will be a bounded queue. A custom Queue implementation can be injected using the 'ref' attribute. Defines a queue with priority-ordering for message reception. Defines a rendezvous queue where a sender will block until the receiver arrives or vice-versa. Defines the dispatching configuration for a non-buffering channel (i.e. one without a queue). Defines a load-balancing strategy for the channel's dispatcher. The default is a round-robin load balancer. [DEFAULT] Defines a Round Robin dispatching strategy which allows for load balancing of messages between multiple Message Handlers. Which message handler receives the message first is determined by the 'order' attribute of such Message Handler. No LoadBalancingStrategy will be used. Specifies whether this dispatcher has failover enabled. By default, failover will be enabled. Set this to 'false' to disable it. When enabled and message delivery to the primary Message Handler fails, an attempt will be made to deliver the message to the next handler and so on... Primary, secondary etc... is determined by the load-balancing strategy in use (e.g. round-robin). If no load-balancer strategy is configured, the order will be fixed in a sequence determined by the 'order' attribute on the Message Handlers (or the @Ordered annotation on adapted methods). Defines a Publish-Subscribe channel that broadcasts messages to its subscribers. Specify whether Exceptions thrown by any subscribed handler should be ignored (only logged). Specify whether the sequence size, sequence number, and correlation id headers should be set on Messages that are sent through this channel. Defines a channel that maintains its Messages on a thread-bound queue. Defines a message channel. This attribute is DEPRECATED. Please use the dispatcher sub-element instead. Enables failover, but disables load-balancing. See the dispatcher sub-element for more information. Defines a Messaging Gateway. Defines a Channel Adapter that receives from a MessageSource and sends to a MessageChannel. Defines a Channel Adapter that receives from a MessageChannel and sends to a method-invoking MessageHandler. Specifies the order for invocation when this endpoint is connected as a subscriber to a SubscribableChannel. Defines an endpoint for exposing any bean reference as a service that receives request Messages from an 'input-channel' and may send reply Messages to an 'output-channel'. The 'ref' may point to an instance that has either a single public method or a method with the @ServiceActivator annotation. Otherwise, the 'method' attribute should be provided along with 'ref'. Base type for Message-handling endpoints. Base type for Message Endpoint elements that accept Messages from an input-channel and also may produce reply Messages to be sent to an output-channel. Base type for Message Endpoint elements that accept Messages from an input-channel. Base type for Message Handlers. Defines an endpoint that passes a Message to the output-channel after a delay. The delay may be retrieved from a Message header or else fallback to the 'default-delay' of this endpoint. Specify the default delay in milliseconds. This value can be set to 0 if the only Messages that should be delayed are those with a particular header (in that case, be sure to provide a value for the 'delay-header-name' attribute). Specify the name of the header that should contain the delay value. This value can either represent the number of milliseconds to delay counting from the current time or it can be an absolute Date until which the Message should be delayed. Provide a reference to the ScheduledExecutorService instance to which this endpoint should delegate when scheduling the sending of delayed Messages. If not provided, the default will use a thread pool of size 1. Specify the maximum amount of time in milliseconds to wait when sending the released Messages (after delay) to the output channel. By default the send will block indefinitely. Specify whether tasks should be able to complete on shutdown. By default this is 'false'. Defines an endpoint that passes a Message to the output-channel without modifying it. Defines an endpoint composed of a chain of Message Handlers. Defines a top-level poller. Defines the configuration metadata for a poller. Defines an interval-based trigger. Defines an cron-based trigger. Defines a MessageSelector chain. Provides a MessageSelector reference. If a method attribute is set the referred bean doesn't need to implement the MessageSelector interface. Defines a HeaderEnricher endpoint for values defined in the MessageHeaders. Defines a Message Header value or ref. Provides the names of the standard configurable MessageHeaders. Defines a ThreadPoolTaskExecutor. Specifies the maximum pool size in order to limit the number of concurrent tasks. Otherwise, the default will be Integer.MAX_VALUE. Defines a Transformer. Defines a Transformer that converts any Object payload to a String by invoking its toString() method. Defines a Transformer that serializes any Object payload that implements Serializable into a byte array. Defines a Transformer that deserializes a byte array payload into an Object. Defines a Filter. Defines a Splitter. Defines an aggregating message endpoint. Defines a resequencing message endpoint. Defines a completion strategy. Defines a list of interceptors. Each element may be a ChannelInterceptor, ref, or inner-bean. Defines a Wire Tap Channel Interceptor.
