SpringBoot+Schedule 定时任务的配置开关

SpringBoot+Schedule 定时任务的配置开关

启动类上添加@EnableScheduling ，开启SpringBoot自带的定时任务功能

@SpringBootApplication @EnableScheduling public class AdminApplication { public static void main(String[] args) { SpringApplication.run(AdminApplication .class, args); } }

创建一个定时任务，间隔5秒执行一次

@Component public class TestScheduling { private static int i = 0; @Scheduled(fixedDelay=5*1000) public void test(){ System.out.println("this is "+ (i++) + "times!"); } }

执行结果

在application.properties中添加定时任务的开关配置

## 定时任务基础配置 scheduling: enabled: true #定时任务开关

修改定时任务的默认注解开关

@Component //默认条件注解是开启的，现在采用配置文件的变量来手动控制定时任务是否执行 @ConditionalOnProperty(prefix = "scheduling", name = "enabled", havingValue = "true") public class TestScheduling { private static int i = 0; @Scheduled(fixedDelay=5*1000) public void test(){ System.out.println("this is "+ (i++) + " times!"); } }
