Spring 引导服务器无法启动嵌入式 tomcat 服务器
Spring boot server fails to start embedded tomcat server
当 运行 启动我的 spring 启动应用程序时，嵌入式 tomcat 服务器无法启动。我刚刚在 pom.xml 中添加了所需的依赖项，并创建了一个简单的 java POJO class。应用程序属性已根据 oracle 数据库的要求以及 Hibernate 方言信息设置为必需的 jdbc 配置。
spring 引导尝试启动服务器并立即将其关闭。控制台中没有发现任何错误。
我已经检查并验证 jdbc url、用户名和密码是否正确，因为如果我不正确地传递它们，我会注意到一个不同的错误。
