本文主要探讨Disruptor框架中的WorkHandler概念，深入解析其在高并发处理中的作用，帮助理解如何利用WorkHandler提升Java应用程序的性能。

为什么80%的码农都做不了架构师？>>>

com.lmax.disruptor.WorkHandler<T>

Callback interface to be implemented for processing units of work as they become available in the RingBuffer.
EventHandler和该接口的区别是WorkHandler的概念是基于worker的处理池

Type Parameters:
<T> event implementation storing the data for sharing during exchange or parallel coordination of an event.
See Also:
WorkerPool
--->>

com.lmax.disruptor.WorkerPool<T>

WorkerPool contains a pool of WorkProcessors that will consume sequences so jobs can be farmed out across a pool of workers. Each of the WorkProcessors manage and calls a WorkHandler to process the events.

Type Parameters:
<T> event to be processed by a pool of workers
事件数据
--->>

EventHandlerGroup<T> com.lmax.disruptor.dsl.Disruptor.handleEventsWithWorkerPool(WorkHandler<T>... workHandlers)

Set up a WorkerPool to distribute an event to one of a pool of work handler threads. Each event will only be processed by one of the work handlers. The Disruptor will automatically start this processors when start() is called.
重点描述的是，每个事件只会被池中的一个任务处理器进行处理

Parameters:
workHandlers the work handlers that will process events.
Returns:
a EventHandlerGroup that can be used to chain dependencies.
