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

View Code
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>
