      事务配置
    3. 部分类的spring bean配置 
      1     <bean id="pku-dic-Dao" class="com.wisdombud.career.dao.impl.DicCommonDaoImpl">
2         <property name="sessionFactory" ref="sessionFactory-pku" />
3     </bean>
      类配置
    4. 说明与坑
      1. 多数据源主要是数据库有多个，而业务上往往决定了需要同时进行两个数据库的操作，因此在配置的时候需要考虑清楚事务一致性需要在什么级别配置；
      2. spring集成hibernate进行事务配置的时候，离不开aop，而aop其实是方法级别的配置，针对某些方法进行切面。如果要切面的类继承了另外一个类，而且父类与子类不在一个包里面，那么在执行父类方法的时候需要aop的话，aop的整体配置pointcut的时候，需要将包含父类的规则包含进来，否则spring不会生成其动态代理。
