	// the password for your private key that you would like to setup HTTPS
	// with. In Eclipse, you can set these options by going to:
	//    1. Run->Run Configurations
	//    2. Under Java Applications, select your run configuration for this app
	//    3. Open the Arguments tab
	//    4. In VM Arguments, provide the following information to use the
	//       default keystore provided with the sample code:
	//
	//       -Dkeystore.file=src/main/resources/private/keystore -Dkeystore.pass=changeit
	//
	//    5. Note, this keystore is highly insecure! If you want more securtiy, you 
	//       should obtain a real SSL certificate:
	//

	// of ObjectMapper in all of the spring data rest classes that rely
	// on the ObjectMapper. This is an example of how Spring dependency
	// injection allows us to easily configure dependencies in code that
	// we don't have easy control over otherwise.
