spring - @Bean List 在实现类中不起作用

Question

我在 Config 类的 @Bean 中有 List：

@Configuration
public class Config {

    @Bean
    public List<IBeer> beers(){
        List<IBeer> beers = new ArrayList<IBeer>();
        beers.add(new Warka("Warka", 4.5, 3.20));
        return beers;
    }
}

...我正在尝试将此 Bean 注入此实现：

public class Order implements IOrder {

    @Value("#{beers[0]}")
    private IBeer beer;

    @Autowired
    private List<IBeer> beers;

    public Order (IBeer beer) {
        super();
        this.beer = beer;
    }

    public void showOrder() {
        System.out.printf("nazwa: " + beer.getName() + "%n" +
               "procenty: " + beer.getAlcoholPercentage() + "%%" + "%n" +
               "cena: " + beer.getPrice() + "PLN" + "%n");
    }

    }

Warka 类只有构造函数（字符串、双精度、双精度）和 3 个 getter，它实现接口 IBeer。类 Order 实现接口 IOrder。

它不应该工作吗？我的项目在这里： https ://github.com/dadziu/nawalmySie/tree/sec
