/**使用多線程的時(shí)候，往往需要?jiǎng)?chuàng)建Thread類，或者實(shí)現(xiàn)Runnable接口，如果要使用到線程池，我們還需要來創(chuàng)建Executors， * 在使用spring中，已經(jīng)給我們做了很好的支持。只要要@EnableAsync就可以使用多線程 * 通過spring給我們提供的ThreadPoolTaskExecutor就可以使用線程池。*///@Configuration 表示該類是一個(gè)配置類@Configuration@EnableAsync//所有的定時(shí)任務(wù)都放在一個(gè)線程池中，定時(shí)任務(wù)啟動(dòng)時(shí)使用不同都線程。
