Exception in thread “main” org.springframework.beans.factory.BeanCreationException: Error creating bean with name “”userManager”” defined in file [E:\java\Hibernate_spring2\bin\applicationContext-beans.xml]: Cannot resolve reference to bean “”sessionFactory”” while setting bean property “”sessionFactory””; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name “”sessionFactory””: Bean with name “”sessionFactory”” has been injected into other beans [txManager] in its raw version as part of a circular reference, but has eventually been wrapped (for example as part of auto-proxy creation). This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching – consider using “”getBeanNamesOfType”” with the “”allowEagerInit”” flag turned off, for example.

10分	别接触过这个异常。但是看了下错误异常并且查了下大概理解为下面几个可能(我是说可能。) 1 SPRING循环依赖但有时候这正是我们想要的，考虑这种情况：我们用一个ManagerFactory来包含所有Manager的声明，以便在程序中用到多个Manager的地方，一个入口集中访问。但是，可能某个Manager本身就需要用到其它几个Manager，进而用到ManagerFactory。这时，我们可以这样声明即可
10分	看你配置文件怎么配置的??
	看异常好像是循环依赖的问题，楼主把相关配置文件给出来吧，这样好定位原因。
	楼主是不是路径写错了，配置文件贴出来啊
10分	一看就是 sessionFactory 写错了。仔细检查下巴。
	出现这样的情况往往是配置文件出现了问题，请仔细检查一下你的配置文件 bean 配置出现了问题
10分	你的dao bean没有注入sessionFactory
	你用的dao是不是用MyEclipes自动集成继承HibernateDaoSupport的，要是这样的话service用到dao，必须依赖注入，否则就会出sessionfactory的错。因为dao跟sessionfactory有依赖关系。希望能帮到你
	<bean id=”userManager” class=”com.dlm.manager.UserManager”> <property name=”sessionFactory” ref=”sessionFactory”/> <property name=”logManager” ref=”logManager”/> </bean> <bean id=”logManager” class=”com.dlm.manager.LogManager”> <property name=”sessionFactory” ref=”sessionFactory”/> </bean> <!– 配置sessionFactory –> <bean id=”sessionFactory” class=”org.springframework.orm.hibernate3.LocalSessionFactoryBean”> <property name=”configLocation”> <value>classpath:hibernate.cfg.xml</value> </property> </bean> <!– 配置事务管理器 –> <bean id=”txManager” class=”org.springframework.orm.hibernate3.HibernateTransactionManager”> <property name=”sessionFactory”> <ref bean=”sessionFactory”/> </property> </bean> <!– 配置事务传播特性 –> <tx:advice id=”txAdvice” transaction-manager=”txManager”> <tx:attributes> <tx:method name=”add” propagation=”REQUIRED”/> <tx:method name=”delete” propagation=”REQUIRED”/> <tx:method name=”update” propagation=”REQUIRED”/> <tx:method name=”” read-only=”true”/> </tx:attributes> </tx:advice> <!– 配置哪些方法参与事务 –> <aop:config> <aop:pointcut id=”allMethod” expression=”execution(* *(..))”/> <aop:advisor pointcut-ref=”allMethod” advice-ref=”txAdvice”/> </aop:config>
	把logManager的bean中的<property name=”sessionFactory” ref=”sessionFactory”/> 去掉。可能就没问题
	还是没解决
