OutOfMemoryError:unable to create new native thread,创建线程数量太多,占用内存过大。一般在实际项目中我们不会使用SimpleAsyncTaskExecutor这种线程池,而是根据实际场景来自定义线程池。下面就和大家一起学习下如何自定义线程池。 线程池配置 对于线程池的优点,想必大家都知道,这里就不赘述了。我们直接上demo。首先...

newCachedThreadPool是Executors工厂类的一个静态函数,用来创建一个可以无限扩大的线程池。 而Executors工厂类一共可以创建四种类型的线程池,通过Executors.newXXX即可创建。下面就分别都介绍一下把。 1. FixedThreadPool public static ExecutorService newFixedThreadPool(int nThreads){ return new ThreadPoolExecutor(nThre...
