Nice Video! I am getting this exception : Consider defining a bean named 'entityManagerFactory' in your configuration. Kindly help me to fix this Koushik.

I created a working project (with Netbeans + NB SpringBoot plugin) with the full source of this course until the lesson 31: www.informatica-libera.net/codenameone/SpringCourse-mysql.zip Please note that I modified the pom.xml and the application.properties to connect to an external MySql database instead of Apache Derby: you can install MySql and modify my application.properties with your MySql username and password and database name. I hope this can be useful.

Before watching this tutorial, I was totally confused about why there is only the definitions in the Repository interface but can not find where their implementation are. Now I see the magic of naming the method name in the Repository interface. Excellent tutorial! Thank you Koushik!

Hi, awesome course, but may be you want to call this a subject instead of topic? When you say topic, it sounds like you are talking about modules in a course which is confusing based on the approach you took to build the entity typeA subject has courses that have topics or modules.

I am getting an Entity Not Found Exception. The error is resolved if I move the Topic class in the same package as the course class. What could be the cause of this exception?
