我曾尝试在互联网上搜索解决方案，但找不到可行的解决方案。
你的堆栈跟踪中的相关部分似乎是这个：
Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
你能试试设置这个吗？我认为 org.hibernate.dialect.Oracle12cDialect 是正确的。只是检查一下，您是否添加了 oracle JDBC 依赖项？
我是 Spring 的新手，正在学习 Spring 与 Hibernate，但我一直卡在这个错误上。我正在使用 Oracle 19c 数据库，我正在使用 Tomcat 8.5 服务器。
