Prerequisites are:

1. You have your Spring Boot project initialized correctly in IDEA
2. JPA persistence.xml file or similar has been generated correctly

Then you have to do these things:

1. Create a DataSource - here you will add a simple DataSource that will connect to your database. The setup should be intuitive - you only provide connection details and add DB drivers (IDEA can download them for you)
2. Add JPA/Hibernate facet. You can do it like this or this .
3. Now you should be able to generate entities using IDEA . What you want to do here is choose Generate by Database Schema . The dialog will let you select the tables you want to use, the rest should be up to you.
