Spring Boot - Senden von E-Mails über Gmail

Ich bin versucht, senden Sie eine E-Mail mit Spring boot, aber ich bin immer der gleiche Fehler. Ich habe versucht, update von maven, saubere Projekte, ich weiß nicht, was ich tun kann.

Field serviceSendEmail in com.stopcozi.resource.AppointmentResource required 
a bean of type 'sendEmail.SendEmail' that could not be found.
Action:
Consider defining a bean of type 'sendEmail.SendEmail' in your configuration.

Habe ich überprüft alle links und versucht zu konfigurieren, dass ein bean auch, aber ich kann nicht damit es funktioniert. Ich habe versucht, alles von hier: Spring Boot 1.2.5.RELEASE - Senden von E-Mails über Google Mail SMTP.
Ich bin mit spring version: 1.4.5.RELEASE.
Bitte werfen Sie einen Blick auf meinen code, vielen Dank.
