Question

我在Config类的@Bean中有列表：

@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;
    }
}

...并且我正在尝试将此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类仅具有构造函数（字符串，双精度，双精度）和3个getter，它实现了接口IBeer。 Class Order实现接口IOrder。

这行不通吗？我的项目在这里： https://github.com/dadziu/nawalmySie/tree/sec

@Bean List在实现类中不起作用
