I read this article:

http://www.ibm.com/developerworks/java/library/j-genericdao.html

several times and believe I understand what it is saying. However, it is 4 years old and I have a JPA compliant Java application to contend with. In addition, I see that there is a JPATemplate in Spring that has some good functionality, but the Spring documentation says it is already deprecated!

Can anybody point me to a solid, modern, JPA compliant, Spring based, working example of a GenericDAOImpl that proxies an Interface to provide generic finder execution?
