Can a spring boot @RestController be enabled/disabled using properties?

Given a "standard" spring boot application with a @RestController, eg

@RestController
@RequestMapping(value = "foo", produces = "application/json;charset=UTF-8")
public class MyController {
    @RequestMapping(value = "bar")
    public ResponseEntity<String> bar(
        return new ResponseEntity<>("Hello world", HttpStatus.OK);
    }
}

Is there an annotation or technique that prevents the endpoint from starting at all if/unless a certain application property exists/doesn't exist.

Note: Testing a property inside the method and exploding is not a solution, because the endpoint will exist.

I don't care about the granularity: ie enabling/disabling just a method or the whole class are both fine.

Because a profile is not a property, control via profiles does not solve my problem.

I found a simple solution using @ConditionalOnExpression:

@RestController
@ConditionalOnExpression("${my.controller.enabled:false}")
@RequestMapping(value = "foo", produces = "application/json;charset=UTF-8")
public class MyController {
    @RequestMapping(value = "bar")
    public ResponseEntity<String> bar(
        return new ResponseEntity<>("Hello world", HttpStatus.OK);
    }
}

With this annotation added, unless I have

my.controller.enabled=true

in my application.properties file, the controller won't start at all.

You can also use the more convenient:

@ConditionalOnProperty("my.property")

Which behaves exactly as above; if the property is present and "true", the component starts, otherwise it doesn't.
