Java + 龙目岛 + 番石榴 + 验证

Question

我有这个 Pojo：@Getter@EqualsAndHashCodepublic class Order {    public enum OrderType {        BUY, SELL    }    private Id id;    private Quantity quantity;    private Money price;    private OrderType orderType;    public Order(Id id, Quantity quantity, Money price, OrderType orderType) {        Preconditions.checkNotNull(id, "id can't be null");        Preconditions.checkNotNull(quantity, "quantity can't be null");        Preconditions.checkNotNull(price, "price can't be null");        Preconditions.checkNotNull(orderType, "orderType can't be null");        this.id = id;        this.quantity = quantity;        this.price = price;        this.orderType = orderType;    }我想做三件事：使用 @AllArgsConstructor 代替并删除构造函数但当然要保持先决条件这可能吗？我也喜欢使用 @Builder 模式，我可以将前提条件与这种方法结合起来吗？

Answer 1

标记所有字段并@lombok.NonNull使用@RequiredArgsConstructor; 应该这样做。
