I am a student studying backend.
I ran into a problem while working on a project using spring boot and jpa.
I couldn't find a solution to this issue. If anyone knows how, please help.
Issue 1.
Message when git commit checkd failed
Checks failed: 1 warning
Warning:(16, 31) 'ConfigurableApplicationContext' used without 'try'-with-resources statement
@SpringBootApplication
public class TrinityApplication {
public static void main(String[] args) {
SpringApplication.run(TrinityApplication.class, args);
}
}
Issue 2.
Error when running spring boot
The "Error creating bean with name 'entityManagerFactory' defined in class path resource" part seems to be the problem. But I can't find a solution.
