Channel Service:

import com.nikita.model.Channel;
import com.nikita.repository.JpaChannelRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service

I myself tried to understand what the problem was all day, none of the methods found on the Internet helped ..

Answer 1

It looks like you are missing the "entityManagerFactory" bean:

No bean named 'entityManagerFactory' available

Try to declare it somewhere.

Answer 2

Hello!
Did you manage to solve the problem?
If not, then I will share some thoughts, and you already debug your code.

Deploying for the first time. through the idea, everything works fine, but when you try to deploy to vps, it gives an error

If it works correctly for you locally, but not on the VPS, then check the server configuration. In your github project, application.yaml is empty and, accordingly, it is not clear what exactly is written in your configs for production. If you have profiles, then check if it hibernate.ddl-auto: validateis installed and if it is installed, whether you have imported ddl & dml to the server. Or do you have it in production should create ddl itself?
At the very least, this is the first point that you should pay attention to.
Next, it’s worth clarifying whether you are deploying the application to an external tomcat or are you using embedded?
Next, try adding this class to your project:

public class ServletInitializer extends SpringBootServletInitializer {

  @Override
  protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(App.class);
  }
}

Next, pay attention to how exactly you build build and what you add to it. For example, war exploded or war or jar. Does it have all required classes in it etc.
If the build is via Gradle, then use bootWar. In general, you need to debug and see what's wrong
