出现的错误是
org.xml.sax.SAXParseException: Element type "bean" must be followed by either attribute specifications, ">" or "/>".
找了很久
<bean id="txManager"class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
发现错误是"txManager"class中间少一个空格。特此记下该错误以备。
