hibernate 错误 懒加载..

Question

Inventory.hbm.xml: N的一方
   <class name="com.flsoft.module.Inventory" table="Inventory" schema="dbo" catalog="UFDATA_789_2010">
        <id name="cinvCode" type="java.lang.String">
            <column name="cInvCode" length="20" />
            <generator class="native"></generator>
        </id>
        <!--  inventoryClass   -->
       <many-to-one name="inventoryClass" class="com.flsoft.module.InventoryClass" fetch="select" lazy="false">
            <column name="cInvCCode" length="12" />
        </many-to-one>
        
InventoryClass.hbm.xml : 1的一方
    <class name="com.flsoft.module.InventoryClass" table="InventoryClass" schema="dbo" catalog="UFDATA_789_2010">
        <id name="cinvCcode" type="java.lang.String">
            <column name="cInvCCode" length="12" />
            <generator class="native"></generator>
        </id>
         <set name="inventories" inverse="true">
            <key>
                <column name="cInvCCode" length="12" />
            </key>
            <one-to-many class="com.flsoft.module.Inventory" />
        </set>
many-to-one 设置lazy="false"了,并且升级到cgli-2.2了
报错信息如下:[ERROR] [org.hibernate.LazyInitializationException.<init>(LazyInitializationException.java:19)] nException - failed to lazily initialize a collection of role: com.flsoft.module.InventoryClass.inventories, no session or session was closed
