Generator class auto-increment in hibernate

Hibernate problems with Auto Increment ID MYSQL 5. Ask Question 8. 2. So, I just stood up a Spring Hibernate app and I can't seem to get my mapping file right. I am using MySql 5 and an auto incrementing key. Here is the ID portion of my mapping file. hibernate generator native class does not increment my user_id column. 2. It would depend on database and how you have created the table. For example if you are using Mysql, then in the table id field should have auto increment set for the field. Hibernate will not generate it, but rather depend on database to do it. If you use Hibernate tools to generate tables, it would take care of generating tables appropriately. I have a j2ee application using hibernate with annotation. How do I annotate the Id field in my pojo class to set it as auto increment or auto generated. and in adding the bean do I leave that fiel.
