其中数据库使用的是MySQL

[执笔记忆的空白]

Caused by: java.sql.SQLException: Table 'test.student' doesn't exist test.student不存在啊 另：参考

是不是cfg.xml中class的name写错了，也就是类似这方面的问题

[Alexzhenyulu]

问题已经解决，在hibernatecfg.xml中加了一句<property name="hbm2ddl.auto">create</property>解决问题。但是不知道为什么

[u010099239]

hibernate.hbm2ddl.auto create：先删除表，再创建表 create-drop：启动时创建表，退出时删除表 update：如果表结构不一致，就创建或更新 validate：启动时验证表结构，如果不一致就抛异常

[qiaodaimadexiaohai]

解决方法：1.数据库是否有'hibernate.ne'这张表。 解决方法： 2.在hibernate.cfg.xml配置文件中加入一行代码 <property name="hibernate.hbm2ddl.auto">update</property>
