业务实现：

package com.ai.rai.group.system;

import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * @version 1.0
 * @ClassName Jobs
 * @Description todo
 * @Author 74981
 * @Date 2018/8/31 15:55
 */
@Component
@EnableScheduling
public class Jobs {
    //CRON表达式参考：http://cron.qqe2.com/
    @Scheduled(cron="0/10 * * * * ?")
    public void executeFileDownLoadTask() {

        Thread t1 = new Thread();
        System.out.println("定时任务1111111111111:"+t1.getId()+" time: "+new Date());
        Thread t2 = new Thread();
        System.out.println("定时任务2222222222222:"+t2.getId()+" time: "+new Date());
        Thread t3 = new Thread();
        System.out.println("定时任务33333333333333:"+t3.getId()+" time: "+new Date());
    }

}

配置文件：

package com.ai.rai.group.system;

import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.aop.interceptor.SimpleAsyncUncaughtExceptionHandler;
import org.springframework.context.annotation.Bean;
import org.springframework.scheduling.TaskScheduler;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;
import org.springframework.stereotype.Component;

import java.util.concurrent.Executor;

/**
 * @version 1.0
 * @ClassName ScheduleConfig
 * @Description todo
 * @Author 74981
 * @Date 2018/8/31 16:24
 */
@Component
@EnableScheduling
public class ScheduleConfig implements SchedulingConfigurer, AsyncConfigurer {
    /*
     * 并行任务
     */
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar)
    {
        TaskScheduler taskScheduler = taskScheduler();
        taskRegistrar.setTaskScheduler(taskScheduler);
    }

    /**
     * 并行任务使用策略：多线程处理
     *
     * @return ThreadPoolTaskScheduler 线程池
     */
    @Bean(destroyMethod = "shutdown")
    public ThreadPoolTaskScheduler taskScheduler()
    {
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.initialize();
        scheduler.setPoolSize(20);
        scheduler.setThreadNamePrefix("task-");
        scheduler.setAwaitTerminationSeconds(60);
        scheduler.setWaitForTasksToCompleteOnShutdown(true);
        return scheduler;
    }

    /*
     * 异步任务
     */
    public Executor getAsyncExecutor()
    {
        Executor executor = taskScheduler();
        return executor;
    }

    /*
     * 异步任务 异常处理
     */
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler()
    {
        return new SimpleAsyncUncaughtExceptionHandler();
    }
}
