首先spring加载BeanA时,发现依赖beanB这时,A会被标记为加载中,去加载beanB,这时加载beanB时发现依赖beanC,beanB标记为加载中,这时加载beanC时发现beanC依赖beanA,而beanA的状态是加载中~~~,这时spring表示玩不下去了,抛出异常BeanCurrentlyInCreationException() spring如何如何避免循环依赖报错 主要是使用刚才说到的...

特别注意最后的评论。通过Thread#interrupt方法是一个合作的过程。当一个线程中断另一个线程时，会导致...
2.1.2 SingleThreadExecutor 的 execute 方法原理 如果当前运行的线程数少于corePoolSize(即线程池中无运行的线程),则创建一个新线程来执行任务。 在线程池完成预热之后(当前线程池中有一个运行的线程),将任务加入LinkedBlockingQueue。 线程执行完1中的任务后,会在一个无限循环中反复从LinkedBlockingQueue获取任务来执...
