搞好多天了都没弄好,各位前辈给看看吧,不是太懂 谢谢了！！
------解决思路----------------------
Constructor threw exception; nested exception is java.lang.IllegalArgumentException: [Assertion failed] - this argument is required; it must not be null
是不是因为
<bean id ="ymUserQqDaoImpl" class="com.yanmad.data.dao.impl.YmUserQqDaoImpl" >
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>只注入了一个属性！
而
private SessionFactory sessionFactory;
private YmUserQqDao ymUserQqDao;
存在两个属性！
------解决思路----------------------
楼上讲的不错，搞不懂为什么要这个属性private YmUserQqDao ymUserQqDao;
要不去掉setYmUserQqDao方法试试
------解决思路----------------------
异常信息很明显了啊：

BaseHibernateDao.java:50的代码是什么！
