Solution 1:^[1]

The version of Spring Boot (2.0.5.RELEASE) that you are using does not support the version of Java that you are using. You should either upgrade to a more recent version of Spring Boot or downgrade to Java 8. I would recommend the former, upgrading to Spring Boot 2.5.x or 2.6.x, as Spring Boot 2.0.x is no longer supported.
