How do I create dummy data when the application starts only in dev profile?

I'm following this article to work with profiles in spring boot. I need to create dummy data when the application starts, but only in the dev profile. How do I achieve this?

My class implements ApplicationRunner and overrides the run method to create the data. I've tried to use the @Profile("dev") annotation as in the article but the data is created irrespective of the active profile.

@SpringBootApplication
public class DemoApplication implements ApplicationRunner {

    @Autowired
    private UserService userService; //handles user saving

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Profile("dev")
    @Override
    public void run(ApplicationArguments arg0) throws Exception {
        User user = new User();
        user.setName("Dummy User");
        userService.save(user);
    }

}

In application.properties, I have

spring.profiles.active=test

A dummy user should be created only when the active profile is dev but it is being created in test profile as well.

@Profile should be marked with @Bean or @Component or its stereotype (i.e @Serivce , @Controller , @Repository etc.)

Simply change it to :

@SpringBootApplication
public class DemoApplication {

    @Autowired
    private UserService userService; //handles user saving


    @Profile("dev")
    @Bean
    public ApplicationRunner devApplicationRunner(){
        return arg->{
           User user = new User();
           user.setName("Dummy User");
           userService.save(user);
        };
    }

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

The code of DEV ApplicationRunner will only run if DEV profile is enabled such as through application.properties:

spring.profiles.active=dev

Try

@Configuration
public class MyWebApplicationInitializer implements WebApplicationInitializer {

  @Override
  public void onStartup(ServletContext servletContext) throws ServletException {
    servletContext.setInitParameter("spring.profiles.active", "dev");
  }

}

or

@Autowired
private ConfigurableEnvironment env;
...
env.setActiveProfiles("dev");

and @Profile only for classes
