Java Spring Boot Web应用程序中的嵌入式Tomcat不以模块信息启动

我想学习一些与java 9+类似的模块的新知识。
因此，我用

springbootstarterweb

和

moduleinfo.java

创建了一个springboot应用程序：

module com.example.demo {
    requires spring.boot;
    requires spring.boot.autoconfigure;

    exports com.example.demo;
    opens com.example.demo;
}

我用过
->Java 15.0.2
->弹簧靴2.4.3
->IntelliJ IDE 2020.3
->Ubuntu 20.04.2 LTS

要运行该应用程序，我使用IntelliJ-default run中的run按钮（绿色箭头），无需任何其他参数。问题是，当我尝试运行应用程序时，嵌入式tomcat服务器没有启动。
输出模块info.java

但是，当我删除

模块info.java

时，一切正常，tomcat服务器启动。
不带模块信息的输出。java

我想知道输出之间的区别。当我使用

module info.java

时，Tomcat不会运行，因为它超出了我的模块

我可以做什么来运行应用程序

您认为，在SpringBoot中使用java模块有什么意义？ 为什么？

为什么不呢？

您需要添加

requires org.apache.tomcat.embed.core要包含
org.apache.catalina.startup.Tomcat.class
