主要是就是这句（org.hibernate.MappingException: Error reading resource: com/test/hibernate/bean/User.hbm.xml），是什么原因导致这样的问题？

vampireii

User.hbm.xml有错,must be declared for element type "hibernate-mapping".

这个就是啊

<property name="username" type="java.lang.String">
            <column name="username"  />
        </property>
你的type写错地方了吧？再看看，可以不可以

按上楼的做了，又是这样一个问题
“Hibernate: insert into user (username, pwd) values (?, ?) select scope_identity()”
org.hibernate.exception.GenericJDBCException: could not insert: [com.test.hibernate.bean.User]

不明白原因

airwalk

你在写save()方法的时候，user.id也要赋值，如果不想设置id,就需要写HQL来实现。

谢谢楼上的，解决了。主键问题
