1、什么getXX()、setXxx(),属性配置对应都没有问题

最后在hbm.xml 中添加一个懒加载属性就OK了

<hibernate-mapping>

<class name="entity.Users" table="USERS" schema="Y2">

<id name="id" type="java.lang.Short">

<column name="ID" precision="4" scale="0" />

<generator class="assigned" />

</id>

.......................

以上是修改前

修改后：

<hibernate-mapping>

<class name="entity.Users" table="USERS" lazy="false"
schema="Y2">

<id name="id" type="java.lang.Short">

<column name="ID" precision="4" scale="0" />

<generator class="assigned" />

</id>
