更改applicationContext-hibernate.xml文件为
<beans>
<!-- Hibernate SessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
<property name="dataSource"><ref bean="dataSource"/></property>
<property name="mappingResources">
<list>
<value>model/Role.hbm.xml</value>
......
<value>model/policy/Policycontent.hbm.xml</value>
</list>
</property>
<property name="lobHandler"><ref bean="oracleLobHandler"/></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">net.sf.hibernate.dialect.Oracle9Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.jdbc.batch_size">15</prop>
</props>
</property>
</bean>
<bean id="oracleLobHandler" class="org.springframework.jdbc.support.lob.OracleLobHandler" lazy-init="true">
<property name="nativeJdbcExtractor"><ref local="nativeJdbcExtractor"/></property>
</bean>
<bean id="nativeJdbcExtractor" class="org.springframework.jdbc.support.nativejdbc.SimpleNativeJdbcExtractor">
</bean>
<!-- Transaction manager for a single Hibernate SessionFactory (alternative to JTA) -->
<bean id="transactionManager" class="org.springframework.orm.hibernate.HibernateTransactionManager">
<property name="sessionFactory"><ref local="sessionFactory"/></property>
</bean>
<!-- LookupDAO: Hibernate implementation -->
<bean id="lookupDAO" class="cn.perfectsoft.hiserviceapp.dao.hibernate.LookupDAOHibernate">
<property name="sessionFactory"><ref local="sessionFactory"/></property>
</bean>
......
<!-- policyTypeDAO: Hibernate implementation -->
<bean id="policyTypeDAO" class="cn.perfectsoft.hiserviceapp.dao.hibernate.policy.PolicyTypeDAOHibernate">
<property name="sessionFactory"><ref local="sessionFactory"/></property>
</bean>
</beans>
在hbm.xml文件中的数据库CLOB类型的映射改为spring提供的ClobStringType
<property
name="policycontent"
type="org.springframework.orm.hibernate.support.ClobStringType"
column="POLICYCONTENT"
length="9000000"//可以在这里定义CLOB使用的大小，而oracle中最大可以使用2G的容量
>
</property>
不要使用hibernate提供的net.sf.hibernate.type.TextType类型
model层的java文件使用String类型即可
利用此配置，完善了AppFuse项目中针对Oracle的CLOB类型不能存储超过4000字符的限制
