Scheduling 配置多线程

*/
@Configuration
@EnableScheduling
public class ScheduleConfig implements SchedulingConfigurer, AsyncConfigurer
{
public void configureTasks(ScheduledTaskRegistrar taskRegistrar)
{
TaskScheduler taskScheduler = taskScheduler();
taskRegistrar.setTaskScheduler(taskScheduler);
}

@Bean(destroyMethod="shutdown")
public ThreadPoolTaskScheduler taskScheduler()
{
ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
scheduler.setPoolSize(8);
scheduler.setThreadNamePrefix("task-");
scheduler.setAwaitTerminationSeconds(60);
scheduler.setWaitForTasksToCompleteOnShutdown(true);
return scheduler;
}

public Executor getAsyncExecutor()
{
Executor executor = taskScheduler();
return executor;
}

public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler()
{
return new SimpleAsyncUncaughtExceptionHandler();
}
}

Scheduling 默认是单线程执行的，同一个时间触发的是串行执行的
