创建线程池

使用Jdk

// 手动构建线程池
        ExecutorService executor = new ThreadPoolExecutor(
                4, 8, 60, TimeUnit.SECONDS,
                new SynchronousQueue<>(),
                new ThreadFactoryBuilder()
                        .setDaemon(false)
                        .setNameFormat("evenExecutor-%d")
                        .build(), new ThreadPoolExecutor.AbortPolicy());

使用Spring

 ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(4);
        executor.setMaxPoolSize(8);
        executor.setKeepAliveSeconds(60);
        executor.setThreadNamePrefix("Executor-");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.AbortPolicy());
