How to use Spring ThreadPoolExecutorFactoryBean factory bean

Question

I would like to be able to embed an instance ExecutorServicein my Spring services, and the Spring API suggests using it ThreadPoolExecutorFactoryBeanfor this purpose. A very simple question; how the hell am i using ThreadPoolExecutorFactoryBeanto create ExecutorServicewhich i can connect to other services?

I feel like a complete idiot to ask his question, but I can’t understand what he understood.
