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

}
