How to get cron from application.yml.

application.yml:

cron-expression:
  every: ${CRON:* * * ? * *}

DTO:

@Configuration
@ConfigurationProperties(prefix = "cron-expression")
class ConfigDTO {
    String every;
       
    public String getEvery(){
        return every;

    }
}

Schedule

public Class Schedule{

@Autowired
private ConfigDTO dto;

    @Scheduled(cron = dto.getEvery())
    public void test(){
       Systems.out.println("date time",newDate());

You can use SPEL (Spring Expression Language) in @Schedule expression

 @Scheduled(cron = "${cron-expression. every}")
 public void test(){
   Systems.out.println("date time",newDate());
 }
