Hibernate实现Clob对象的存取

1.建表
create table tablename (
   id  number(10),
   content clob
) CONSTRAINT "PK_ID" PRIMARY KEY ("id");

2.spring xml文件配置
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
   <property name="hibernateProperties">
      <props>
         <prop key="hibernate.connection.SetBigStringTryClob">true</prop>
      </props>
   </property>
   <property name="lobHandler" ref="oracleLobHandler" />
</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.WebLogicNativeJdbcExtractor"
   lazy-init="true" />

3.TableTest.hbm.xml文件
<class name="MyTableTest" table="T_Table_Test">
   <id name="id" type="java.lang.Long">
      <column name="ID" />
      <generator class="sequence">
         <param name="sequence">SEQ_Table_Test</param>
      </generator>
   </id>
   <property name="content" type="org.springframework.orm.hibernate3.support.ClobStringType">
      <column name="CONTENT">
         <comment>内容</comment>
      </column>
   </property>
</class>

4.TableTest.java文件
public class TableTest {
   private Long id;
   private String content;
   // getter setter
}
