各位大侠,请教hibernate.cfg.xml的问题

[wayne0920]

我在class路径下配置hibernate.properties文件测试可以，但在同一目录下配置hibernate.cfg.xml就不行出现错误如下：

org.hibernate.HibernateException: Hibernate Dialect must be explicitly set
at org.hibernate.dialect.DialectFactory.determineDialect(DialectFactory.java:57)
at org.hibernate.dialect.DialectFactory.buildDialect(DialectFactory.java:39)
at org.hibernate.cfg.SettingsFactory.determineDialect(SettingsFactory.java:378)

yunxiang(无名)说得对！

[yksky]

空指针,cn.pengwang.demo.demotest.findAllCustomers(demotest.java:29)
看看这行有哪个参数没有设置值?或者在hbm文件中设置为not null,而这里又没有给它赋值?

[聪头]

把源码贴出来。
好像是缺少一个参数值“Hibernate Dialect must be explicitly set”

[yunxiang]

<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>

这句话加了么?
它是指定你用什么数据库语言.我这里写的是oracle
报错信息就是说你这个参数必须设置.

[yksky]

恩,其实如果是Oracle9i的话,那么就应该是Oracle9Dialect

谢谢，问题解决了！！
