In Spring MVC, we can set active profile programmatically in our WebApplicationInitializer implementation.

Example

Environment related beans

public interface GreetingService {
    String getGreetingMsg();

    @Service
    @Profile("dev")
    class DevGreetingService implements GreetingService {

        @Override
        public String getGreetingMsg() {
            return "hi from dev";
        }
    }

    @Service
    @Profile("prod")
    class ProductionGreetingService implements GreetingService {

        @Override
        public String getGreetingMsg() {
            return "hi from production";
        }
    }
}

Example Controller

@Controller
public class ExampleController {
    @Autowired
    private GreetingService greetingService;

    @RequestMapping("/")
    @ResponseBody
    public String handle() {
        return greetingService.getGreetingMsg();
    }
}

Web Initializer

public class MyWebInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) {
        AnnotationConfigWebApplicationContext ctx =
                new AnnotationConfigWebApplicationContext();
        ctx.getEnvironment().setActiveProfiles("dev");
        ctx.register(AppConfig.class);
        ctx.setServletContext(servletContext);
        ServletRegistration.Dynamic servlet =
                servletContext.addServlet("springDispatcherServlet",
                        new DispatcherServlet(ctx));
        servlet.setLoadOnStartup(1);
        servlet.addMapping("/");
    }
}
