Mysql 更改数据库名称时，Hibernate事务未成功启动

我正在将一个web应用程序部署到一个tomcat容器，连接到一个mysql容器。当我部署war时，在我创建MySQL数据库（通过

hibernate.cfg.xml插入）之后，一切都很好

但是，如果我想将我的web应用程序连接到一个新数据库，该数据库是在我将war部署到webapps/文件夹后创建的，我有以下几行代码：

我怎样才能解决这个问题

这是我的
hibernate.cfg.xml
文件：

我的目标是从我最初的.war创建一个新的（复制的）web应用程序。因此，我重命名了我的war，将其部署到webapps/，并编辑了
hibernate.cfg.xml
。如果我重命名我的war并将其指向初始db，则一切正常。当我指向另一个db时，会出现此问题。事实上，在日志中，有初始web应用程序（/ShoppingAT）的“上下文路径”。
您如何切换到另一个数据库？指向其他数据库后是否重新启动webapp？你的配置文件是什么？另外，您发布的stacktrace似乎不完整（或者至少：我希望stacktrace0.1中会出现异常原因。我已通过php myadmin创建了新的数据库；2.部署了新的war；3.修改hibernate.cfg.xml以指向新的数据库。4.重新启动tomcat容器。请参阅我编辑的日志
