Springboot集成SpringTask
基于注解配置
第一步
在springboot启动类中添加注解@EnableScheduling
package top.simba1949; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.scheduling.annotation.EnableScheduling; /** * @author simba@onlying.cn * @date 2018/7/9 20:08 */ @SpringBootApplication @EnableScheduling // 支持schedule定时任务 public class App { public static void main(String[] args) { SpringApplication.run(App.class,args); } }
第二步
编写定时任务
package top.simba1949.task; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; import java.text.SimpleDateFormat; import java.util.Date; /** * @author simba@onlying.cn * @date 2018/7/10 20:52 */ @Component public class MySpringTask { private Logger logger = LoggerFactory.getLogger(MySpringTask.class); /** * spring task,@Scheduled(cron = "0/5 * * * * ? ")即可开启定时任务 */ @Scheduled(cron = "0/5 * * * * ? ") public void doTask(){ logger.info(new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(new Date()) + " "+ Thread.currentThread().getName()); } }
基于配置文件
第一步
创建applicationContext-task.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 扫描组件 --> <context:component-scan base-package="top.simba1949.task" /> <!-- 配置调度器,声明十个线程的池 --> <task:scheduler id="myScheduler" pool-size="10"/> <!-- 配置任务 --> <task:scheduled-tasks scheduler="myScheduler"> <!--ref引用的定时任务的Bean,method指定该bean要执行的方法--> <task:scheduled ref="mySpringTask" method="doTask" cron="0/5 * * * * ? "/> <!--配置定时任务2--> <task:scheduled ref="mySpringTask02" method="doTask" cron="0/3 * * * * ? "/> </task:scheduled-tasks> </beans>
第二步
将配置文件加入spring容器管理
package top.simba1949.config; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.ImportResource; /** * @author simba@onlying.cn * @date 2018/7/9 20:09 */ @Configuration @ImportResource(locations = "applicationContext-springtask.xml") public class SpringTaskConfig { }
第三步
编写定时任务
package top.simba1949.task; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; import java.text.SimpleDateFormat; import java.util.Date; import java.util.concurrent.ThreadFactory; /** * @author simba@onlying.cn * @date 2018/7/10 20:52 */ @Component public class MySpringTask { private Logger logger = LoggerFactory.getLogger(MySpringTask.class); /** * spring task,@Scheduled(cron = "0/5 * * * * ? ")即可开启定时任务 */ public void doTask(){ logger.info(new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(new Date()) + " "+ Thread.currentThread().getName()); } }
