java - MockMailSender class automatically autowired to MailSender? -

i have implemented mockmailsender as:

@service  public class mockmailsender implements mailsender {      private logger log = loggerfactory.getlogger(this.getclass());      @override     public void send(simplemailmessage message) throws mailexception {         log.info("to: " + message.getto());         log.info("subject: " + message.getsubject());         log.info("body: " + message.gettext());     }      @override     public void send(simplemailmessage... messages) throws mailexception {         (simplemailmessage message: messages              ) {             send(message);         }     } } 

good thing automatically @autowired mailsender object in @restcontroller class. when run code in testing doesn't send email mocks it. problem how can disable default behaviour if want code in production?

personally @profile approach. mark first service annotation @profile("test") , create second implementation of mailsender interface sends email itself.

@service @profile("production")  public class mailsenderimpl implements mailsender {     // log & send } 

autowire service , use it. advantage right 1 injected conditionally although there exists more beans of same interface:

@autowired mailsender mailsender; 

you can configure current environment (aka profile) following configuration:

@configuration public class environmentconfiguration implements webapplicationinitializer {      @override     public void onstartup(servletcontext sc) throws servletexception {         sc.setinitparameter("spring.profiles.active", "test");     } } 

i not sure how spring-boot manage configuration. anyway, recommend read more @ spring docs - 25. profiles , spring-boot profiles @ mkyong's.
