Answer 1

Answer to your question
From effective Spring 2.5.x versions, have a concept of stereotyped Annotations you have to mark to your classes with these annotations to make it eligible for component scanning.
In your case you have mark your DAOImpl class with #Repository annotation like this given below.
#Repository
public class StudentHibernateDaoImpl implements StudentDAO {
Change your component scan tag as
<context:component-scan
base-package="edu.java.spring.controller,yourPackage.StudentHibernateDaoImpl"/> >
Here is an example which will resolve your issue.
