如下是一个Executors的使用案例,展示了用一个固定大小的线程池来并发执行任务,如下代码: import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.TimeUnit; public class ThreadPoolExample { public static void main(String[] args) { // 创建一个固定大小...

我提到的是『不建议』,但是在阿里巴巴Java开发手册中也明确指出,而且用的词是『不允许』使用Executors创建线程池。 阿里巴巴的规范手册里面说的是严令禁止使用的。因此,大家也可以完全的遵守一下吧 简单例子模拟一下OOM 代码语言:javascript 代码运行次数:0
