Question

我最近刚开始使用Spring MVC，我正在使用hibernate将数据保存到数据库中。我正在学习本教程：http://gerrydevstory.com/2013/06/29/spring-mvc-hibernate-mysql-quick-start-from-scratch/并且我难以理解下面的这一个错误。我确保hibernate-core在类路径中，所有其他库都放在类路径中.. < / p>

有人可以提供一些指导吗？谢谢。

我最近将一个旧项目从Hibernate 3.2迁移到了4.2。确实SessionImplementor从org.hibernate.engine移到了org.hibernate.engine.spi it('should throw Error with message \'UNKNOWN ERROR\' when no params were passed', (t) => { const error = t.throws(() => { throwError(); }, TypeError); expect(t).toThrowError('UNKNOWN ERROR'); //or expect(t).toThrowError(TypeError); });。其他几个类/接口也被移动了。

我最近将此项和其他项添加到migration guide published by RedHat。

设置hibernate时找不到sessionImplementor类
