No bean named 'entityManagerFactory' available when module descriptor is added
Question
I want to develop a modular app that uses a MySql db, Java 11 and spring boot. The app works perfectly well until I add the module descriptors; so I can only guess I am missing something in the module-info.java, but I can't figure out what it is. I appreciate any help. Here is my code

The primary cause of the exception seems to be
Caused by: java.lang.NoClassDefFoundError: java/sql/SQLException
At the same time, the mention in your question that the "app works perfectly well until I add the module descriptors", seems to indicate that prior to introducing the module-info.java , your application must have been using the classpath, where it was able to find the class mentioned above through transitive dependencies.
1 Another aspect would be, that your application doesn't directly need this class, else you would have faced a compile-time error stating that the imports are unrecognized.
This boils down to the module dependencies that you've mentioned in your application's descriptor, so one or more of them requires java.sql.SQLException now to be present on the modulepath and has itself missed specifying that explicitly (quite possible in the case of automatic modules). You would need to identify which module(s) amongst those required by you could need the specific class for a long term resolution.
1 One way would be then to say, report it to the library/module owner and ask them to define an explicit dependency. This might require you to wait for them to be modular themself and then make use of the upgraded version. In such a case, you can until there upgrade add an argument to your application
--add-modules=java.sql
Another could be that your application itself at runtime needs the java.sql module and that the libraries just make use of it when declared by you explicitly. In this case, the solution would be to add the following to your module-info.java file:
requires java.sql

I have gone through your stack-trace. Can you try below steps
- Remove @Repository annotation from UserRepository.java
- Remove @EnableJpaRepositories from DemojpaApplication only if UserRepository.java is in sub package of main DemojpaApplication.java
