一、该问题的重现步骤是什么？

1. 使用@Component和@PostConstruct注解

2. 打包后用java -jar运行项目出现报错

TestStartUpClass {
   INoticeService () {
      System..println()List<Notice> list = .list()list.forEach(System.::println)System..println()}

}

二、你期待的结果是什么？实际看到的又是什么？

想要在项目运行后执行一个方法，进行查询数据库，然后再根据查到的数据创建定时任务。

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

SpringBlade，3.6.0RELEASE，Windows

四、请提供详细的错误堆栈信息，这很重要。

五、若有更多详细信息，请在下面提供。

不只是使用@Component和@PostConstruct注解会出现这个报错，使用ApplicationRunner或者在原来的Application中调用service查询数据库都会出现报错

TestStartUpClass {
   INoticeService () {
      System..println()List<Notice> list = .list()list.forEach(System.::println)System..println()}
}

源码是这个，pom.xml文件未经过修改
