Strategy pattern with spring beans

Question

Say I\'m using spring, I have the following strategies...

Interface

public interface MealStrategy {
    cook(Meat meat);
}

First st

Answer 1

Since a concrete strategy is very often determined at run time based on the provided parameters or so, I would suggest something as follows.

@Component
public class BurgerStrategy implements MealStrategy { ... }

@Component
public class SausageStrategy implements MealStrategy { ... }

Then inject all such strategies into a map (with bean name as a key) in the given controller and select respective strategy on request.

@Autowired
Map mealStrategies = new HashMap<>;

@RequestMapping(method=RequestMethod.POST)
public @ResponseBody Something makeMeal(@RequestParam(value="mealStrategyId") String mealStrategyId, Meat meat) {
    mealStrategies.get(mealStrategyId).cook(meat);

    ...
}
