Jboss 下 Hibernate 的连接错误

spring+hibernate的工程从tomcat5.5移植到JBoss4.2.2。

    spring  2.5.4

    hibernate 3.2

在tomcat下均正常。但是在JBoss下执行如下查询的时候出现错误：

 

 

   private final static SessionFactory sessionFactory;

   private static final ThreadLocal threadSession = new ThreadLocal();

   private static final ThreadLocal threadTransaction = new ThreadLocal();
   
   
   public static void beginTransaction() throws DaoException {
      Transaction tx = (Transaction) threadTransaction.get();
      try {
         if (tx == null) {
            tx = getSession(true).beginTransaction();
            threadTransaction.set(tx);
         }
      } catch (HibernateException ex) {
         log.error("Fail to begin transaction", ex);
         throw new DaoException("Fail to begin transaction", ex);
      }
   }
    

   public static Session getSession(boolean openSession) throws DaoException {
      Session s = (Session) threadSession.get();
      //if (openSession) {            //2008-12-17
      if ((openSession)&&(s==null)) {
    	  
         try {
            if (s == null) {
               s = sessionFactory.openSession();
               threadSession.set(s);
            }
         } catch (HibernateException ex) {
            log.error("Fail to open session", ex);
            throw new DaoException("Fail to open session", ex);
         }
      }
      return s;
   }
   
    public List findByCriterions(Class clazz, List restrictions)
      throws DaoException {
      List objs = new ArrayList();
      
      try {
         Session session = this.openSession();
         beginTransaction();
         Criteria criteria = session.createCriteria(clazz);
         Iterator it = restrictions.iterator();
         while (it.hasNext())
            criteria.add((Criterion) it.next());
         objs = criteria.list();
         if (autoCommit)
            commitTransaction();
      } catch (HibernateException ex) {
         rollbackTransaction();
         log.error("Fail to find objects by criterions", ex);
         throw new DaoException("Fail to find objects by criterions", ex);
      } finally {
         if (autoCloseSession)
            closeSession();
      }
      return objs;
   }
   
   
   

 

tx = getSession(true).beginTransaction();
 出错

 

错误信息如下：

奇怪的是并非每次执行都有错误，偶尔也会成功！

 

 

目前采用的是webserver的JNDI连接池。

 

 搜了很久，有兄弟建议用c3p0连接池，http://bjzhanghao.cnblogs.com/archive/2004/12/10/75145.html  19楼。

于是修改spring-hibernate配置如下：

	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="dataSource"><ref bean="dataSource" /></property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">org.hibernate.dialect.DB2Dialect</prop>
				<prop key="hibernate.show_sql">false</prop>
				<!-- add for c3p0 连接池 -->
				<prop key="hibernate.c3p0.min_size">5</prop> 
				<prop key="hibernate.c3p0.max_size">20</prop> 
				<prop key="hibernate.c3p0.timeout">1800</prop> 
				<prop key="hibernate.c3p0.max_statements">50</prop> 
			</props>
		</property>
		<property name="configLocation" value="classpath:/config/hibernate/hibernate.cfg.xml"/>
	</bean>
	<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
		<property name="sessionFactory" ref="sessionFactory"></property></bean>
	<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>
	<tx:annotation-driven transaction-manager="transactionManager" />

    依然没有解决，错误依旧。

    更有兄弟说只是调试信息，没影响。http://hbird.vicp.net/viewthread.php?action=printable&tid=2157

 

    求指点！

已解决：

我试了一下，如果不用JNDI，直接在spring里写datasource的配置，则不会出现该错误。

 

rain2005 (中级程序员) 2008-12-18

的解决方法：

       现在使用的是JBOSS的dataSource，不是使用的c3p0当然报错拉

 

两种方式：

1、采用c3p0数据源配置连接池：

    

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"  
        destroy-method="close">  
        <property name="driverClass">  
            <value>com.ibm.db2.jcc.DB2Driver</value>  
        </property>  
        <property name="jdbcUrl">  
            <value>jdbc:db2://172.21.21.2:50000/HOSPDB</value>  
        </property>  
        <property name="user">  
            <value>db2admin</value>  
        </property>  
        <property name="password">  
            <value>dhcc</value>  
        </property>     
     ......   
</bean>  

2、如果使用JNDI的话，transactionManager也得改成jboss提供的事务管理器。具体配置可以参考spring文档中的JTA事务管理。
