Field required a bean of type ... that could not be found

Question

In my Spring project I have an interface:

public interface MyIntefrace {

    void myMethod(String myParam);
}

and I have a class that implements it:

@Component
@Profile("prod")
public class MyImplementationClass implements MyInterface {
    ...

In my other class, I'm using this object as follows:

@Autowired
MyInterface myinterface;

...

myinterface.myMethod(someParam);

And it throws me an error:

Field myinterface in mypackage required a bean of type ... that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Consider defining a bean of type '...' in your configuration

I tried to add @Service annotation above MyInterface but that didn't help. What else can I do?

Make sure the prod profile is enable such as through :

1. JVM property :

   -Dspring.profiles.active=prod

2. Or environment variable:

   export spring_profiles_active=prod

3. Or programmatically when creating ApplicationContext:

   AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext();
   //...........
   ctx.getEnvironment().setActiveProfiles("prod");
   ctx.refresh();
