Spring Boot 调度程序问题

Question

I have a simple Spring Boot app that handles some REST API calls and so on. I added @EnableScheduling to my main class and then proceeded to add @Scheduled on top of each function I need to schedule and then added a cron expression.

Spring boot Version : 2.7.1

What I have is the following:

I have three classes. Each class contains a void function scheduled.

I ran the app and everything seems working fine. All the API calls ran smoothly and as excepted, and then I ran the same app but from a jar file using the cmd. The scheduler works fine the first day and then suddenly stops working and then starts working again the day after.

I was monitoring the logs and it turned out that 4 out of 5 days the scheduler ran as expected, but skipped one day for no reason.

Any one might experienced this weird behavior?

main class:

@EnableScheduling
@SpringBootApplication
public class MYCLASSHERE {

    public static void main(String[] args) {
        SpringApplication.run(MYCLASSHERE.class, args);
    }
}

each class has the following structure:

@Service
public class MYOTHERCLASS{
@Scheduled(cron = "0 5 12 * * *")
    public void FUNCTION() {}
}

@Service
public class MYOTHERCLASS{
@Scheduled(cron = "0 10 12 * * *")
    public void FUNCTION() {}
}

@Service
public class MYOTHERCLASS{
@Scheduled(cron = "0 15 12 * * *")
    public void FUNCTION() {}
}

Note that everything is working fine. The scheduler stoppage that I'm experiencing is the only problem when running from a jar file.

Answer 1

尝试 @Scheduled(cron = "0 35,40 14 * * ?") 为您的功能
