Question

我的项目最初开发使用的是持久性单元和项目是spring，Struts2是hibernate整合的一个。现在我需要使用jboss连接池和持久性单元。任何人都可以指导我以最短的方式在该要求中转换项目。当前的spring.xml

</bean>
<bean id="springdatasource"

    class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="hibernateProperties">

<bean id="divAction" class="action.DevisionAction">

示例DAO类

public class DevisionDaoImpl implements DevisionDao {


private SessionFactory sessionfactory;

public void setSessionfactory(SessionFactory sessionfactory) {
    this.sessionfactory = sessionfactory;
}
@Override
public List showDiv() {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void addDiv(AtDivision div) {
    Session session = sessionfactory.openSession();
    Transaction tx = null;
    try {
        tx = session.beginTransaction();
        session.saveOrUpdate(div);
        tx.commit();
        //System.out.println("after save : " + org.getAoId());
    } catch (Exception e) {
        if (tx != null) {
            tx.rollback();
        }
        e.printStackTrace();
    } finally {
        session.close();
    }
}

}

Answer 1

1：更改数据源配置以使用jboss数据源。这可以这样做：

<jee:jndi-lookup id="springdatasource" jndi-name="your-de-jndi-name" />

2：使用spring transaction manager添加事务管理器来控制事务：

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
  <property name="sessionFactory" ref="sessionFactory" />
</bean>

3：为spring事务添加注释支持。将其添加到您的配置中：

<tx:annotation-driven transaction-manager="transactionManager" />

4：最后用@Transactional
