It is possible to schedule that the Spring cache is always redone at midnight?

I read the Springs Cache Docs and I found nothing about how to get him to be regenerated.

  • Has the answer helped you to resolve the doubt? It is possible to accept it now?

  • Good afternoon, @Murilo, there have been other priorities over the past few weeks and the past. I’m coming back to this solution now and I’m already responding.

Something that could be done is to use cache expiration (@CacheEvict) together with the scheduling (Scheduled), as below:

@Configuration
@EnableCaching
@EnableScheduling
public class CachingConfig {
    public static final String GAMES = "GAMES";
    @Bean
    public CacheManager cacheManager() {
        ConcurrentMapCacheManager cacheManager = new ConcurrentMapCacheManager(GAMES);

        return cacheManager;
    }

    @CacheEvict(allEntries = true, value = {GAMES})
    @Scheduled(cron = "* * 0 * * ?")
    public void reportCacheEvict() {
        System.out.println("Flush Cache " + dateFormat.format(new Date()));
    }
}
