我正在运行一个带有mysql，web，jpa作为依赖项的spring boot应用程序。我已经使用数据库属性配置了109文件。日志附有以下详细信息：
application.properties我已经创建了git存储库，并将我的代码上传到Github-Link to Github repo

供参考
pom.xml我应该如何调试此错误。请告诉我，因为这里发生了很多魔术。

应用程序日志中的条件评估报告显示，尚未将嵌入式Servlet容器配置为javax.servlet.ServletRequest不在类路径中：
ServletWebServerFactoryAutoConfiguration:
Did not match:
- @ConditionalOnClass did not find required class 'javax.servlet.ServletRequest' (OnClassCondition)
它应该在类路径上，因为您对spring-boot-starter-web有依赖性，该依赖项会拉入tomcat-embed-core，其中包含所有Servlet API类。应用程序日志还显示C:\Users\classpath\.m2\repository\org\apache\tomcat\embed\tomcat-embed-core\8.5.32\tomcat-embed-core-8.5.32.jar在类路径上。
要使jar文件位于类路径上，并且找不到该文件包含的类，则jar文件必须已损坏。当Maven下载jar时，可能会发生这种情况。尝试删除C:\Users\classpath\.m2\repository\org\apache\tomcat\embed\tomcat-embed-core\8.5.32\目录并重建应用程序。这将导致Maven下载jar的新副本，希望这次不会损坏它。

最后，我能够解决此问题。我删除了.m2中的存储库目录，并再次构建了整个项目。这次成功了。
