REST based micro-services sample

tl;dr

• Three Spring Boot based Maven projects that are standalone applications:
  • Stores (MongoDB, exposing a few Starbucks shops across north america, geo-spatial functionality)
  • Customers (JPA)
  • Customers UI (Angular and Spring Boot CLI backend)
• The customers application tries to discover a search-by-location-resource and periodically verifying it's still available (see StoreIntegration).
• If the remote system is found the customers app includes a link to let clients follow to the remote system and thus find stores near the customer.
• Hystrix is used to monitor the availability of the remote system, so if it fails to connect 20 times in 5 seconds (by default) the circuit will open and no more attempts will be made until after a timeout.
