问题描述

配置问题，求大神解惑

我使用的是applicationContext.xml配置

  <!-- 配置自动扫描的包 -->

  <!-- 配置数据源 -->

  <!-- 配置 Hibernate 的 SessionFactory 实例 : 通过Spring 提供的LocalSessionFactoryBean配置-->
  <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <!-- 配置数据源属性 -->
    <property name="dataSource" ref="dataSource"></property>

    <!-- 配置 hibernate 配置文件的名称及位置 -->

    <!-- 使用hibernateProperties属性来配置Hibernate原生的属性 -->
    <property name="hibernateProperties">

    <!-- 配置 hibernate 映射文件的位置及名称 ， 可以使用通配符-->
    <property name="mappingResources">

   <value>bean/card.hbm.xml</value>

  </bean>

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

    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="find*" propagation="REQUIRED" />

        <aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
    </aop:config>
</beans>

执行

 package test;
import org.hibernate.Session;
import org.hibernate.Transaction;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

import bean.card;
import bean.test;
public class test1{
    /**
     * @param args
     */

    public static void main(String[] args) {
         SessionFactory sessionFactory = null;
         Configuration configuration = new Configuration().configure();
         ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties())
                .buildServiceRegistry();
            sessionFactory = configuration.buildSessionFactory(serviceRegistry);
          //SessionFactory sf = new AnnotationConfiguration().configure().buildSessionFactory()  注解为AnnotationConfiguration
            //2. Sesson
            Session session = sessionFactory.openSession();
            //3. 开启事务
            Transaction transaction = session.beginTransaction();
            //4. 执行保存操作
           card t=new card();
            t.setCardid("123");
            t.setCardnum(12221);
            t.setId(12);
            session.save(t);
            //5. 提交事物
          transaction.commit();
            //6. 关闭Session
          session.close();
            //7. 关闭SessionFectory
          sessionFactory.close();
           System.out.println("成功！");
}}

报下面这个错 是为什么呢？
```Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found

解决方案

<!-- <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> -->
<!-- 使用hibernateProperties属性来配置Hibernate原生的属性 -->
    这个文件配置的地方你已经注释掉了，spring扫描的时候，扫描不到，还有就是这个文件需要凡在和applicationContext.xml文件同样的包下面
