org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'deptDao_a' defined in class path resource [beansAndHibernate.xml]: Cannot resolve reference to bean 'sessionFact

 Error creating bean with name 'deptDao_a' defined in class path 

因为更改了类的名字，所以其setter方法没有更改，需要

private  DeptDao_a deptDao_a;

public void setDeptDao_a(){

}   

set后的名字需要更改
