hibernate异常
1.No entries available
myeclipse 自动生成映射文件时出现No entries available,这是因为没有增加Hibernate特性,在项目上点击右键选择MyEclipse选项,为应用增加Hibernate特性,如果你已经手动将jar包放入lib下面了,那就什么jar包都不要选,最后完成只需生成一个hibernate.cfg.xml文件即可
2.org.hibernate.hql.ast.QuerySyntaxException: unexpected token: * near line 1, column 9
hql =" select * from User where userno='" + userno + "'";
去掉select前面的空格也不行,改成"from User where userno='" + userno + "'",才可以
3.Mapping directory location [ServletContext resource [/User.hbm.xml]] does not denote a directory
1 <property name="mappingDirectoryLocations"> 2 <list> 3 <value>classpath:com/hk/mananarbook/entity</value> 4 </list> 5 </property>
4.org.hibernate.HibernateException: No CurrentSessionContext configured!
在hibernate.cfg.xml中session-factory段加入:
<property name="current_session_context_class">thread</property>
