Java spring boot应用程序正在关闭，无错误

我正在运行一个springboot应用程序，其中mysql、web、jpa作为依赖项。我已经用数据库属性配置了

application.properties

文件。有关以下详细信息，请参阅日志：

我已创建git存储库并将代码上载到Github-

我还附上了

我应该如何调试此错误。请告诉我，这里有很多神奇之处。

应用程序日志中的条件评估报告显示嵌入式servlet容器未配置为

javax.servlet。ServletRequest

不在类路径上：

ServletWebServerFactoryAutoConfiguration:
  Did not match:
     - @ConditionalOnClass did not find required class 'javax.servlet.ServletRequest' (OnClassCondition)

它应该在类路径上，因为您依赖于

springbootstarterweb

，它引入了包含所有Servlet API类的

tomcatembeddedcore

。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

位于类路径上

---

要使jar文件位于类路径上并且找不到它所包含的类，jar文件必须已损坏。当Maven下载jar时，就会发生这种情况。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，我解决了这个问题。我删除了

.m2

中的存储库目录，并再次构建了整个项目。这一次，它成功了。

您是如何启动服务器的？@Pramod正在IntelliJ Idea中以java程序的形式运行CrudApplication。您能分享一下pom吗。xml@zilcuanu以

spring boot:run

为目标，以maven项目的形式运行该项目。@Pramod如何在IntelliJ Idea上做到这一点？如何启动服务器？@Pramod运行CrudApplication作为IntelliJ Idea的java程序。请分享一下pom。xml@zilcuanu以
