我试图在我的春天@Scheduled方法中定义cron细节
@Service
@PropertySource("classpath:application.properties")
public class CacheRefreshService {
@Scheduled(cron = "${api.refresh.cron}")
public void refreshJob() throws Exception {
LOGGER.info("Started Refresh");
//do something
}
}
在我的application.properties
中#Refresh
api.refresh.cron =0 29 11 * * ?
当我使用@Scheduled定义cron细节时,它运行正常。但是当我这样做时,它无法从属性文件中读取值,并抛出以下错误。
Caused by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'refreshJob': Cron expression must consist of 6 fields (found 1 in "${api.refresh.cron}")
有什么建议吗?

将以下内容添加到我的ApplicationContext中解决了问题..
@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}

factoryBean.setCronExpression(“ 0 0/1 * 1/1 *?*”); 您必须在BeanFactory类中设置Cron Expresssion bcz,而setCronExpression是必需的
