Spring Boot on Appengine standard doesn't start - spring-boot

Question

I created a simple ( and almost empty ) spring boot project, I packaged into a jar and I deployed it on appengine.
But it doesn't start!
When I run https://.appspot.com I Have a 500 error page
I saw the database was created and the tables too, but there is something wrong into application
These are the last few lines of the log
Started VibesCoreApplication in 9.729 seconds (JVM running for 11.147)
Shutting down ExecutorService 'taskScheduler'
Closing JPA EntityManagerFactory for persistence unit 'default'
HikariPool-1 - Shutdown initiated...
HikariPool-1 - Shutdown completed.

Answer 1

I was able to find a similar issue with yours here. The fact is that ( even this should not happen ) the configuration loading order may be broken.
In the post that I have sent you, the solution was removing the #EnableAutoConfiguration annotation.
