请帮我仔细分析一下该段java代码配置: @Configuration @EnableScheduling public class ScheduledConfig implements SchedulingConfigurer { @Override public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) { scheduledTaskRegistrar.setScheduler(setTaskExecutors()); } @Bean public Executor setTaskExecutors(){ ScheduledExecutorFactoryBean scheduledExecutorFactoryBean = new ScheduledExecutorFactoryBean(); scheduledExecutorFactoryBean.setPoolSize(50); scheduledExecutorFactoryBean.setThreadNamePrefix("core-task"); scheduledExecutorFactoryBean.initialize(); return scheduledExecutorFactoryBean.getObject(); } @Bean public ExecutorService myExecutorService() { int corePoolSize = 25; int maximumPoolSize = 150; long keepAliveTime = 30000; TimeUnit timeUnit=TimeUnit.MILLISECONDS; BlockingQueue<Runnable> queue=new ArrayBlockingQueue<Runnable>(1000); ThreadFactory threadFactory=new ThreadFactory() { int no=0; @Override public Thread newThread(Runnable runnable) { Thread thread=new Thread(runnable); thread.setName("core-executor-thread-"+no); no++; thread.setContextClassLoader(Thread.currentThread().getContextClassLoader()); return thread; } }; return new ThreadPoolExecutor( corePoolSize, maximumPoolSize, keepAliveTime, timeUnit, queue, threadFactory ); } }
