The problem is that UserEntity is in a different package.

Trying adding these annotations to your ClubapiApplication class:

@Configuration
@ComponentScan({"eu.upcom.api", "eu.upcom.model"})

Using IntelliJ IDEA, I connected to a MySQL database so that I will be able to use the tables as classes. With a module I've done that. But when I am trying to run an empty Controller the following exceptions are been thrown.

Project Structure

Database Scheme

EDIT I tested my project with a very simple database that contains only one table and two fields and the same exceptions are happening!

Still the same exceptions

There are annotations above getters and setters that's why I included only one getter and setter to point at that. As for your other solution, the same exceptions are happening. Keep in minded that UserEntity and the other classes from model package, are created automatically from the MySQL database.

Annotations are extremely important in Spring - please update the above code and include your annotations so we can review - otherwise no one will have a hope of even pointing you in the right direction

The autogeneration isn't the issue - the problem is related to how your Entity classes are being wired up - the managed type exception is related to how Spring Data is trying to complete the auto wiring of the class - it sees that it needs to be wired but cant figure out how to do so

I updated the UserRepository and also added the auto generated getters and setters. As you can see, your suggestions were already implemented. But of course I added them again on variable declaration.
Robert H almost 7 years

The getters and setters should not be annotated, what happens if you remove those annotations?
Manolis Pap almost 7 years

It doesn't accept a comma between them. The annotation becomes red. After your edit, sadly the same exceptions appear.

Same exceptions

I added database scheme if you want to take a look.
Manolis Pap almost 7 years

No worries, I saw it. I don't know if you saw my edit as well. The same exceptions are appearing. I added a database schema as well.
Robert H almost 7 years

Have you tried using a stand-alone table (with no relations) and seeing if you can get it to work correctly?
Manolis Pap almost 7 years

I just did. A simple database with just one table and two fields and the same exceptions are happening!
Robert H almost 7 years

Well something funky is going on - honestly I'd have to dig deeper than my time allows, final suggestion would be if you haven't already - spin up a new project all together, no MVC - just basic application and wire in your a JpaRepository for the table, an annotated POJO representing the table and a basic test to check functionality. If that works then build off that until you find your issue. I suppose its possible your issue is in your persistance.xml file - not too sure as I don't use one, but best of luck!

Thank you for your suggestions and your time

Try adding just @ComponentScan("com.upcom.*") along with @Configuration
