also there have been no other changes to my code not sure what is causing this really .

app class is as simple as below

  SpringApplication.run(HfServices.class, args);

Please help ...

Answer 1

That method was added in Spring Framework and you are overriding the version explicitly in your project. Please don't do that!

Spring Boot is managing this for you and you should really let it determine the Spring Framework version to use.
