Spring Boot : Getting @Scheduled cron value from database

you can add a bean to get cron value from database in the SpringBootApplication main class or in any of the configuration class. Example code is below:

@Autowired
private CronRepository cronRepo;

@Bean
public int getCronValue()
{
    return cronRepo.findOne("cron").getCronValue();
}

you should create a table and provide suitable values in the database. After that you can provide the bean inside the @Scheduled. Example code is below:

@Scheduled(cron="#{@getCronValue}")

Hope it works for your issue.
