如何正确使用休眠注释？

Question

I just set up a basic hibernate/spring project to test some stuff. I use a MySQL db by using WAMP.

These are all of the classes: http://codepaste.net/7pwmtx

This is my bean definition and pom file: http://codepaste.net/4iz7jb

POM is a little bit messy but this is the problem: I think that I set up my dialect properly because I get no errors when i add something to the db. I get errors when I use find in hql. I t seems like hibernate isnt retrieving data from the same place that it is putting it. Any idea why this doesnt work?

By the way, the console output was:

Add the entity class to hibernate.cfg.xml files. It is neeeded even if you are using annotation based configurations.

If you want to skip adding these to cfg file you can use the approach mentioned here provided you are using .
