java - 遇到无效的 @Scheduled 方法 'run' : Exactly one of the 'cron' , 'fixedDelay(String)' ，或需要 'fixedRate(String)' 属性

Question

不知道可能是这里的问题，只是向我的应用程序添加了一个标准的 cron 作业，如果它是硬编码的，它就可以工作!

application.properties

qronicle.data-retention.retryCronSchedule = 0 * * * * *

数据保留传递方法

@Scheduled(cron = "\${qronicle.data-retention.retryCronSchedule}")
@Transactional
override fun run() {
    LOGGER.info("Running retry job.")

    val retentionRecords = retentionRepository.findAllByStateAndRetryCountLessThan()
    LOGGER.info("Will attempt to reprocess ${retentionRecords.size} retention records.")

抛出以下错误

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2019-06-18 14:02:25.221 ERROR 20 --- [           main] o.s.boot.SpringApplication               : Application run failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'retentionRetryJob$qronicle' defined in class path resource [com/netapp/qronicle/config/ApplicationConfig.class]: Initialization of bean failed; nested exception is java.lang.IllegalStateException: Encountered invalid @Scheduled method 'run': Exactly one of the 'cron', 'fixedDelay(String)', or 'fixedRate(String)' attributes is required

值得一提的是，在 IntelliJ 中运行应用程序似乎可以工作，

giving the following log line...
2019-06-18 17:30:35.388  INFO 15642 --- [           main] c.n.q.p.delivery.RetentionRetryJob       : Started retention retry job with schedule: 0 * * * * *.

在 java 中不可能将动态值传递给注释。您可以查看这篇文章以供引用。
