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!");
    }
}
