我是Springboot的新手，正在尝试重新创建我的教师应用程序，但在运行时出错

运行应用程序的@Springbootapplication主类位于前端模块中。我该如何告诉应用程序？我尝试了这些步骤，在根pom文件中添加了一个springboot-maven插件，但仍然没有成功。我还试图减少包的数量，并使application.class尽可能靠近src文件夹，尽管这些都不重要，因为它对我的老师有效。
这是我的根pom文件：

这是我试图重新创建的存储库
我在这里遇到了类似的错误，我的代码找不到主类，我将此属性添加到pom.xml文件中：
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
这里的一切都很顺利。
我找到了使用命令的正确方法
mvn清洁包装弹簧靴：重新包装
导航到只包含主类的模块(在我的情况下是前端模块(，然后运行
mvn干净安装
