Migrated to Spring Boot 2.2.2.RELEASE and Hoxton.RELEASE

[ctornau]

I migrated the example to Spring Boot 2.2.2.RELEASE and Hoxton.RELEASE.

However different questions came up while migrating it:

(1) Including the Eureka reference fails with

[ERROR] Some problems were encountered while processing the POMs:
'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-eureka:jar is missing. @ line 34, column 15

I removed the reference. I think the example should be upgraded to Consul?

(2) One of the tests envPostAvailable() is failing with the message:

WARN 11844 --- [o-auto-1-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported]

This message comes out of Spring Config. Is POST not supported anymore?
