Answer 2

报错不是说你的USER_CD字段插入NULL了user.setUserCd(Integer.parseInt(userCd));
这里如果你的userCd确实有值的话，，那你看你hibernate的映射文件中。配置的属性和列的配置是否正确。。如表的列名是否正确

</hibernate-mapping>这是hibernate映射文件 系统生成的。应该没有问题吧。。

Answer 4

配置文件中。。你的USER_CD字段配置了自增的那你的实体中UserCd属性应该不设置值了。。

Answer 5

 <generator class="assigned" />

Answer 6

<generator class="identity" />是对的，save的那个对象，主键设置null进去就行。
此外建表的时候，要 id int identity(1,1) primary key,
