springboot中定时任务

 import java.text.SimpleDateFormat;
 import java.util.Date;

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

 /**
  * 测试spring定时任务执行
  */
 @Component
 @Configuration
 @EnableScheduling
 public class MyTestTask {
     private static final SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

     @Scheduled(cron="* * * * * *") // 关于定时任务执行时间,后续会在别的文章中添加
     public void executeUpdateYqTask() {
         System.out.println(Thread.currentThread().getName() + " >>> task one " + format.format(new Date()));
     }

     @Scheduled(cron="* * * * * *")
     public void executeRepaymentTask() throws InterruptedException {
         System.out.println(Thread.currentThread().getName() + " >>> task two " + format.format(new Date()));
     }
 }

 import java.util.concurrent.Executor;

 import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
 import org.springframework.aop.interceptor.SimpleAsyncUncaughtExceptionHandler;
 import org.springframework.context.annotation.Bean;
 import org.springframework.context.annotation.Configuration;
 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;

 @Configuration
 @EnableScheduling
 public class ScheduleConfig implements SchedulingConfigurer, AsyncConfigurer{

     /** 异步处理 */
     public void configureTasks(ScheduledTaskRegistrar taskRegistrar){
         TaskScheduler taskScheduler = taskScheduler();
         taskRegistrar.setTaskScheduler(taskScheduler);
     }

     /** 定时任务多线程处理 */
     @Bean(destroyMethod = "shutdown")
     public ThreadPoolTaskScheduler taskScheduler(){
         ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
         scheduler.setPoolSize(20);
         scheduler.setThreadNamePrefix("task-");
         scheduler.setAwaitTerminationSeconds(60);
         scheduler.setWaitForTasksToCompleteOnShutdown(true);
         return scheduler;
     }

     /** 异步处理 */
     public Executor getAsyncExecutor(){
         Executor executor = taskScheduler();
         return executor;
     }

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

最后：

在启动类加上    @EnableScheduling　就可以了

 /**
  * 启动类
  */
 @SpringBootApplication
 @EnableScheduling
 public class AppApplication extends SpringBootServletInitializer {}
