错误描述：系统在运行一个不定的时间后，在数据库中会产生一个未提交的事务，经查访问
日志，通常是在添加或更新操作时产生的，该事务所在的连接被其他线程使用后，会导致其他数据
库操作都被阻塞，最终导致系统无法访问。该错误经开发人员手动测试和压力测试都未能重现，数
据均能正常提交，而且在多个dao中都会出现。
系统环境:
redhat5,oracle10,jdk1.6,tomcat6,spring2,hibernate3,dbcp
以下是某个Dao的典型代码及配置
public class BaseDAO {
public final int RESULT_FETCH_SIZE=100;
protected DataSource dataSource = null;
protected SessionFactory sessionFactory = null;
protected HibernateTemplate ht = null;
protected JdbcTemplate jt = null;
public void setSessionFactory(SessionFactory factory)
{
sessionFactory = factory;
ht = new HibernateTemplate(sessionFactory);
}
public BaseDAO()
{
}
public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
jt=new JdbcTemplate(dataSource,false);
}
}
实现的dao
public class CmsmailboxDao extends BaseDAO implements ICmsmailboxDao{
public void createBean(final Cmsmailbox bean) throws DataAccessException{
this.ht.save(bean);
}
public Cmsmailbox getBean(String ctid) throws DataAccessException {
return (Cmsmailbox) this.ht.get(Cmsmailbox.class, ctid);
}
public Collection getBeans(final String cmbid,final String cmbtitle,final int offset, final int rowsToReturn, final String sort,
final String order) throws DataAccessException {
return (Collection) ht.execute(new HibernateCallback() {
public Object doInHibernate(Session session)
throws HibernateException {
StringBuffer buf = new StringBuffer();
buf.append("from com.xxx.Cmsmailbox bean ");
......
Query query = session.createQuery(buf.toString());
......
return query.list();
}
});
}
......
}

以上是dao的一种典型配置
下面是事务管理器的配置，实际上我的应用并未用到事务处理，只是出现上述错误后，怀疑
是未加事务管理器的问题，结果加上后问题依旧
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory"><ref
bean="sessionFactory"/></property>
</bean>
<bean id="transactionInterceptor"
class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager" ref="transactionManager"/>
<property name="transactionAttributes">
<props>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<bean
class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<value>*Dao</value>
</property>
<property name="interceptorNames">
<list>
<value>transactionInterceptor</value>
</list>
</property>
</bean>
目前已经可以排除的可能：1、数据库，在sqlserver下也会出现；2、jdbc驱动；3、hibernate及spring的版本；4、连接池，dbcp和c3p0都会出现
感觉对于spring中使用hibernate的方式应该没有错误，应该是哪个地方的配置或是某个部分对整体架构产生了影响，希望大家都能来讨论下，给点思路
问题补充
现在已经是true了
那个不设是所有的操作都不会写到数据库
问题补充
昨天用wvs测安全，居然把这个错误重现了，初步判断是和HibernateTemplate的并发有关
