Spring 引导调度程序非法访问异常 tomcat

Question

我在专用 tomcat 服务器上有一个 spring 启动 war 应用程序运行。我在该应用程序中有一个计划任务：
@Scheduled(cron = "0 0 4 15/1 3/10 ?")

当我关闭 tomcat 服务器（在我的 Intellij IDEA 中）时，我得到这个堆栈跟踪：

30-Dec-2020 15:01:02.191 INFO [main] org.apache.coyote.AbstractProtocol.stop Stopping ProtocolHandler ["http-nio-8080"]

这种行为是故意的吗？

编辑：
正如@Andres Sacco 正确地假设的那样，将它添加到我的 pom 中解决了这个问题：

<!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-core -->
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>1.2.3</version>
        </dependency>

此问题的解决方案是添加库“logback-core”，因为您的 pom 文件中不存在。
