Springboot中使用Scheduled做定时任务---http://www.cnblogs.com/lirenqing/p/6596557.html
已经验证的方案:
pom文件加入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
ExampleTimer.java
package com.example; import java.text.SimpleDateFormat; import java.util.Date; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; @Component public class ExampleTimer { SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss"); @Scheduled(fixedRate = 10000) public void timerRate() { System.out.println(dateFormat.format(new Date())); } //第一次延迟1秒执行,当执行完后2秒再执行 @Scheduled(initialDelay = 1000, fixedDelay = 2000) public void timerInit() { System.out.println("init : "+dateFormat.format(new Date())); } //每天20点16分50秒时执行 @Scheduled(cron = "50 16 20 * * ?") public void timerCron() { System.out.println("current time : "+ dateFormat.format(new Date())); } }
3、启动应用程序
启动程序,需要增加@EnableScheduling注解.
