关于sessionFactory or hibernateTemplate is required

我把Spring和Hibernate整合起来时，遇到个错误搞了好久，按照网上的方法也没法解决

抛出错误如下：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.lfw.sh.manager.impl.UserManagerImpl#10b4b2f' defined in class path resource [applicationContext-commom.xml]: Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: sessionFactory or hibernateTemplate is required

java.lang.IllegalArgumentException: sessionFactory or hibernateTemplate is required

Spring配置文件如下：

</property> 
</bean> 
</beans> 
      

老是提示：sessionFactory or hibernateTemplate is required

让我很郁闷的是：我明明把sessionFactory注入进去了呀，怎么还是找不到的？

后来认真观察错误 Error creating bean with name 'com.lfw.sh.manager.impl.UserManagerImpl#10b4b2f' defined in class path resource

才发现原来是在creating UserManagerImpl类时找不到sessionFactory，

于是把

<bean id="userManager" parent="baseTxService"> 
<property name="target"> 
<bean class="com.lfw.sh.manager.impl.UserManagerImpl" /> 
</property> 
<property name="sessionFactory"> 
<ref bean="sessionFactory"/> 
</property> 
</bean> 
      

改为：

<bean id="userManager" parent="baseTxService">
        <property name="target">
            <bean class="com.lfw.sh.manager.impl.UserManagerImpl">
            	 <property name="sessionFactory">
        			<ref bean="sessionFactory"/>
        		 </property>
            </bean>
        </property>
       
    </bean>
	
	      

就搞定了，后来经一位高人指点得知：我的com.lfw.sh.manager.impl.UserManagerImpl继承了org.springframework.orm.hibernate3.support.HibernateDaoSupport, spring在初始化容器的时候会对这个对象作一个check, 看下HibernateDaoSupport源码中的checkDaoConfig()方法就清楚啦:

protected final void checkDaoConfig() {   
        if (this.hibernateTemplate == null) {   
            throw new IllegalArgumentException("'sessionFactory' or 'hibernateTemplate' is required");   
        }   
    }  
           

所以，在com.lfw.sh.manager.impl.UserManageImpl对象一定要注入一个sessionFactory or hibernateTemplate对象。
