spring boot应用程序关闭时没有错误
提问于 2018-08-16 12:37:00
我正在运行一个spring引导应用程序，其中mysql、web、jpa作为依赖项。我已经使用数据库属性配置了application.properties文件。下面附上日志以了解更多详细信息：

应用程序日志中的条件评估报告显示嵌入式servlet容器尚未配置，因为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，因为您对spring-boot-starter-web有一个依赖，它拉入包含所有Servlet API类的tomcat-embed-core。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。
如果jar文件位于类路径上，并且找不到它包含的类，则该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\目录并重新构建应用程序。这将导致Maven下载一个新的jar副本，并且希望这次不会损坏它。

最后，我终于解决了这个问题。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。
