hibernate 执行hql语句出现数据默认值错误

今天在建user表后使用hibernate进行查询时出现以下异常：

 Null value was assigned to a property of primitive type setter of com.bbs.model.User.memberPoint 指的是null值被付给了基本类型memberpoint，再类user中memberpoint是int类型，而数据库中memberpoint的默认值是null，如果是一般的sql语句倒不会出现问题，但是使用hql语句时hibernate会将提取的数据封装成对象，在封装的过程中就会把null值付给memberpoint，从而出现异常。

解决办法是将数据库中的memberpoint字段的默认值设成类中的类型，比如int可以设成0，这样就不会出现把null值赋给基本类型的情况了。
