spring 对hibernate 事务管理问题

spring 版本为2.0.7 hibernate版本为3.2.5.ga


spring 配置文件为






   <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
              <property name="jndiName" value="java:comp/env/jdbc/jdbm"/>
          </bean>


<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"  destroy-method="close">
<property name="dataSource" ref="dataSource" />



<property name="mappingLocations">
<list>
<value>classpath*:com/jdapp/db/cc/po/*.hbm.xml</value> 
          

</list>
</property>

<property name="hibernateProperties">

   <!-- Transaction manager for hibernate  -->
    <bean id="myTransactionManager"  class="org.springframework.orm.hibernate3.HibernateTransactionManager">

源代码程为 TestDao.java

package com.jdapp.db.cc.dao;

import java.sql.SQLException;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;




import com.jdapp.db.cc.po.Depinfo;

public class TestDao  extends HibernateDaoSupport implements TargetLogicInc

{


public void save(Depinfo de)


{
System.out.println(this.getHibernateTemplate().find(" from Depinfo").size());

  


try {
this.getHibernateTemplate().save(de);
if(true) {
throw new Exception();

}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}






}




}


按照我的意愿,应该不会向数据库交提, 但结果每次都向数据库提交了.请大家看看我的代码什么地方出了问题?

我的TargetLogic是没用的
