配置文件的size,对应ThreadPoolExecutor的corePoolSize以及maximumPoolSize
自定义ThreadPoolExecutorDispatcher
Dispatcher dispatcher = new ThreadPoolExecutorDispatcher(5, 2048,"dispatcherGroup",
new LinkedBlockingQueue<Runnable>(2048),
new ThreadPoolExecutor.DiscardOldestPolicy());
EventBus eventBus = EventBus.create(eventBusEnv,dispatcher);
