spring boot + Schedule简单定时任务实现

1、启动类加注解@EnableScheduling

package cn.sunline.insd.sso.service;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.EnableHystrix;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication(scanBasePackages = { "${app.scan.packages}" })
@EnableEurekaClient
@EnableHystrix
@EnableCircuitBreaker
@EnableScheduling
public class InsdSimpleWebApplication {
	public static void main(String[] args) {
		SpringApplication.run(InsdSimpleWebApplication.class, args);
	}
}

2、编写测试类，需要@Component管理，需要执行的定时任务加注解@Scheduled(cron="cron表达式")

package cn.sunline.insd.sso.scheud;

import org.apache.log4j.Logger;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class ScheduledTest {
	private static final Logger logger = Logger.getLogger(ScheduledTest.class);

	@Scheduled(cron="*/5 * * * * ?")
	public void executeFileDownLoadTask() {
		// 间隔5秒,执行任务    
		Thread current = Thread.currentThread(); 
		System.out.println("定时任务1:"+current.getId());
		logger.info("ScheduledTest.executeFileDownLoadTask 定时任务1:"+current.getId()+ ",name:"+current.getName());
	}
}

3、执行效果
