2、Spring配置出现There is no ID/IDREF binding for IDREF错误

　　今天在折腾Spring配置工厂的时候，出现了There is no ID/IDREF binding for IDREF错误，异常信息如下：

ERROR ContextLoader:215 - Context initialization failed

Caused by: org.xml.sax.SAXParseException: cvc-id.1: There is no ID/IDREF binding for IDREF 'sessionFactory'.

  从错误提示中可以发现，这个错误与sessionFactory有关，sessionFactory是HibernateSessionFactory类的对象，已经在spring的配置文件applicationContext.xml中配置的，因此查找子配置文件（springForOthers.xml）发现如下配置：

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

　　错误就出现在红色加粗的local这里，使用local的话是指示在当前分配文件中查找id为sessionFactory的bean，而正确的方式是使用<ref bean="sessionFactory" />，将local改成bean表示从所有的bean中查找，不仅仅是查找当前的配置文件了，通过这样的设置后，错误就解决了。
