Answer 1

TeacherTest是你写的代码吧，异常堆栈列表中，下面的信息
com.Hibernate.TeacherTest.beforClass(TeacherTest.java:22)
说明在这个类的程序的22行，即beforClass方法中，提交给数据库的sql语句有问题，你可以把这个语句周围的代码贴出来看看。
抛出的是SQLException，说明已经把请求提交给数据库了，数据库在执行sql语句是发生了错误，这样的错误才会被java包装成 SQLException，所以不应该是配置文件之列的问题，应该检查程序中的sql语句。

Answer 2

检查下数据源配置和方言配置，可能是这方面的原因。只贴异常栈无法确定到底哪地方有问题。

Answer 3

应该是数据库配置有问题，查看配置文件吧

Answer 4

啊，这么多的英文吓死我了
