-------------------------------
hbm文件中categoryId的配置是
<id
name="categoryId"
type="integer">
<column name="CATEGORYID" sql-type="number" length="38"/>
<generator class="sequence">
<param name="sequence">SEQ_CATEGORY</param>
</generator>
</id>


－－－－－－－－－－－－－－－－－－－－
Category类的categoryId属性是int，我改为Integer还是报错，改成long也是一样

java.lang.ClassCastException: java.lang.Integer
at test.model.dao.impl.CategoryDao.saveCategory(CategoryDao.java:23)
转型异常,看看你saveCategory这个方法里面,是不是有什么错误了
