Getting this error when trying to run my Java with Maven using Intellij:

                Can you please add DEBUG=true in your application.properties, relaunch and update the question with the full stack-trace from the log?

                1) Welcome to SO, please use @username when replying to someone's comment, so they get notified. 2) If the entity code you posted is the latest version, the problem seems to be what Stefan answered so it's a duplicate of this question. Try changing to the correct import, clean and rerun the application, and add the new stacktrace if different. If it's the same, depending on how you run your app, please make sure that you're using updated sources/jars.

                @LedBaron are you sure, you removed the wrong import and added the import Stefan mentioned? Because your exception tells you, that it was caused by hibernate not finding the ID of your entity.

                @JuliusHörger It did work i just didn't notice i had another problem. org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource is now the next challenge to overcome...

                @LedBaron sweet! Usually on SO, if an answer fixes your problem, you can chose it as the "correct" one by clicking the "v" in on the left side of the number of votes, so it can help others with similar problems to easily identify the solution. Alternatively you can up-vote an answer if it was of any help, or down-vote it if it was "garbage", thus further helping to to separate the useful from the impractical information.

When I got this error, it turned out to be due to the fact that I was attempting to access the application context in a field initialization or constructor in a class (in this case AuthenticationFilter extends UsernamePasswordAuthenticationFilter) that gets instantiated BEFORE THE CONTEXT IS AVAILABLE.
myField  = (MyClass)SpringApplicationContext.getBean(MyClass.BEAN_NAME);
By moving this statement to a method that gets called early in this class's lifecycle but long after the constructor, the error was resolved and the app started up normally.
The really annoying thing, as with much of the opaqueness of Spring Boot's dependency injection model, is that while at the end of the day it was a classic case of NullPointerException, the log wouldn't give the class and line number where the error was occurring; so I was on my own to deduct from indirect evidence what was going on.
I got the same error today,
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2022-06-12 12:40:23.851 ERROR 12764 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : APPLICATION FAILED TO START
And after a few research found a solution, that I missed the @Service annotation in my Service class.
Just adding that solved my problem.
