hi,i'm new in hibernate and spring,this is my config,but its not in a transaction,it seems has no transaction,
applicationContext.xml file:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >
<property name="configLocation" value="classpath:jbpm.hibernate.cfg.xml" />
<property name="dataSource" ref="dataSource" />
</bean>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>

<aop:config>
<aop:pointcut expression="execution(* com.test.TransAction.*(..))" id="txPointcut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
</aop:config>

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >

<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@172.17.1.1:1521:database" />
<property name="username" value="test" />
<property name="password" value="test" />
</bean>

<bean id="transAction" class="com.test.TransAction">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
hibernate file:
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
<property name="hibernate.format_sql">false</property>
<property name="hibernate.jdbc.batch_size">0</property>

</session-factory>
</hibernate-configuration>


test class:
public class TransAction extends HibernateDaoSupport {
private SessionFactory sessionFactory;


public void testTrans3() throws RuntimeException{
Session session=this.getSession();


SQLQuery query1=session.createSQLQuery("update deployment set timestamp_='20120219'");
query1.executeUpdate();

SQLQuery query=session.createSQLQuery("update deployment set timestamp_='20120301089089058795789'");
query.executeUpdate();

}
}
when it runs,the first sql is updated,and the second sql throws exception,but first sql cannt rollback,what's wrong with my config,can anyone help me? thanks a lot

You probably missed to open a transaction explicitly by calling

Code:
session.getTransaction().begin();


so all your updates were executed with autocommit (=single implicit transaction per jdbc-statement).

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>

<aop:config>
<aop:pointcut expression="execution(* com.test.TransAction.*(..))" id="txPointcut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>

What do you mean with 'auto transaction'?

I suggest you to read the hibernate documentation, chapter "Database transaction demarcation"

What codes do you want? Can you specify on what are you working?
