How to solve configuration class error while deploying spring boot app on Google App Engine? - spring

Question

I've created a spring boot application and it works well on my machine. Now I want to deploy the application of google app engine and with refer link. After that I've run two magical commands called mvn install and mvn appengine:update. It gave me a success message as well. Now, when I try to run my application it shows 500 error and in log I found mentioned error.
P.S: I've added #SpringBootApplication on my application class.

Google AppEngine does not allow JMX, so you have to switch it off in a Spring Boot app (set spring.jmx.enabled=false in application.properties).
application.properties
spring.jmx.enabled=false
