| Package | Description | 
|---|---|
| org.springframework.core.task | This package defines Spring's core TaskExecutor abstraction,
 and provides SyncTaskExecutor and SimpleAsyncTaskExecutor implementations. | 
| org.springframework.core.task.support | Support classes for Spring's TaskExecutor abstraction. | 
| org.springframework.http.client | Contains an abstraction over client-side HTTP. | 
| org.springframework.messaging.handler.invocation | Common infrastructure for invoking message handler methods. | 
| org.springframework.messaging.simp.stomp | Generic support for simple messaging protocols (like STOMP). | 
| org.springframework.messaging.tcp | Contains abstractions and implementation classes for establishing TCP connections via
  TcpOperations,
 handling messages viaTcpConnectionHandler,
 as well as sending messages viaTcpConnection. | 
| org.springframework.messaging.tcp.reactor | Contains support for TCP messaging based on Reactor. | 
| org.springframework.mock.http.client | Mock implementations of client-side HTTP abstractions. | 
| org.springframework.scheduling.annotation | Java 5 annotation for asynchronous method execution. | 
| org.springframework.scheduling.commonj | Convenience classes for scheduling based on the CommonJ WorkManager/TimerManager
 facility, as supported by IBM WebSphere 6.0+ and BEA WebLogic 9.0+. | 
| org.springframework.scheduling.concurrent | Scheduling convenience classes for the  java.util.concurrentandjavax.enterprise.concurrentpackages, allowing to set up a
 ThreadPoolExecutor or ScheduledThreadPoolExecutor as a bean in a Spring
 context. | 
| org.springframework.scheduling.quartz | Support classes for the open source scheduler
 Quartz,
 allowing to set up Quartz Schedulers, JobDetails and
 Triggers as beans in a Spring context. | 
| org.springframework.util.concurrent | Useful generic  java.util.concurrent.Futureextension. | 
| org.springframework.web.client | Core package of the client-side web support. |
