Struts2+hibernate+spring事务配置没起作用

Question

struts.xml

<action name="index" class="indexAction">

    <result name="success">/top5w.jsp</result>

</action>

applicationContext.xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">


   <property name="driverClassName"><value>com.mysql.jdbc.Driver</value></property>


   <property name="url"><value>jdbc:mysql://localhost:3306/te</value></property>


   <property name="username"><value>root</value></property>


   <property name="password"><value>root</value></property>


   <property name="maxActive"><value>100</value></property>


   <property name="maxIdle"><value>20</value></property>


   <property name="maxWait"><value>100</value></property>


</bean>   

<bean id="sessionFactory"  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">


      <property name="dataSource" ref="dataSource" />


      <property name="hibernateProperties">


          <props>


              <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>


              <prop key="hibernate.show_sql">true</prop>


          </props>


      </property>


      <property name="mappingLocations">


          <list>


             <value>classpath:com/zhang/tao/model/*.hbm.xml</value>


          </list>


      </property>


  </bean>


 <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">


    <property name="sessionFactory" ref="sessionFactory" />


 </bean>   

<bean id="indexAction" class="com.zhang.struts.action.IndexAction" scope="prototype">


    <property name="wordService" ref="kwordService" />


 </bean>   

<bean id="kwordService" class="com.zhang.struts.service.KwordService">


<property name="sessionFactory" ref="sessionFactory" />


</bean>

KwordService.java

   private SessionFactory sessionFactory;   

public SessionFactory getSessionFactory() {   
    return sessionFactory;   
}   

public void setSessionFactory(SessionFactory sessionFactory) {   
    this.sessionFactory = sessionFactory;   
}   

public List<?> getResult(String hql,int currPage){   


//      Session session = sessionFactory.openSession();


        Session session = sessionFactory.getCurrentSession();


        Transaction tr = session.beginTransaction();


        Query query = session.createQuery(hql);


        query.setFirstResult(50*currPage);


        query.setMaxResults(50);


        List<?> list = query.list();


        tr.commit();


//      session.close();


        return list;


    } 

IndexAction.java

    private KwordService wordService;   

public String toIndex(){


    HttpServletRequest request = ServletActionContext.getRequest();


    List<?> list = null;


    String hql = "from com.zhang.tao.model.Kword";


    list = wordService.getResult(hql,1);

如果在KwordService.java里用sessionFactory.openSession()就OK，但用getCurrentSession()就报错
如果在kwordservice类里使用session = sessionFactory.openSession();就OK，如果使用getCurrentSession()就报错
org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

你都没有配置事件拦截器嘛

配置声明式事务的方法如下。主要利用BeanNameAutoProxyCreator自动创建事务代理

  <bean id="transactionInterceptor"
  class="org.springframework.transaction.interceptor.TransactionInterceptor">
  <property name="transactionManager">
   <ref bean="transactionManager" />
  </property>
  <!-- 配置事务属性 -->
  <property name="transactionAttributes">
   <props>
    <prop key="delete*">PROPAGATION_REQUIRED</prop>
    <prop key="add*">PROPAGATION_REQUIRED</prop>
    <prop key="update*">PROPAGATION_REQUIRED</prop>
    <prop key="save*">PROPAGATION_REQUIRED</prop>
    <prop key="find*">PROPAGATION_REQUIRED,readOnly</prop>
   </props>
  </property>
 </bean>

 <bean
  class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
  <property name="beanNames">
   <list>
    <value>fundService</value>
   </list>
  </property>
  <property name="interceptorNames">
   <list>
    <value>transactionInterceptor</value>
   </list>
  </property>
 </bean>
