如何在類中根據枚舉值，獲取枚舉的message的工具類

枚舉類為：

public enum OrderStatusEnum implements CondeEnum{
    NEW(0, "新訂單"),
    FINISHED(1, "完結"),
    CANCLE(2, "取消");

    private Integer code;
    private String msg;

    OrderStatusEnum(Integer code, String msg) {
        this.code = code;
        this.msg = msg;
    }

    public Integer getCode() {
        return code;
    }

    public String getMsg() {
        return msg;
    }
}

實現的接口為：

public interface CondeEnum<T> {

    T getCode();
}

然后實現一個工具類：

public class EnumUtil {

    public static <T extends CondeEnum> T getByCode(Integer code, Class<T> enumClass) {
        for (T each : enumClass.getEnumConstants()) {
            if (code.equals(each.getCode())) {
                return each;
            }
        }
        return null;
    }
}

在實體類中直接進行賦值：

@Data
@JsonInclude(JsonInclude.Include.NON_NULL)
public class OrderDTO {

    private String orderId;

    private String buyerName;

    private String buyerPhone;

    private String buyerAddress;

    private String buyerOpenid;

    private BigDecimal orderAmount;

    private Integer orderStatus = OrderStatusEnum.NEW.getCode();

    private Integer payStatus = PayStatusEnum.WAIT.getCode();

    @JsonSerialize(using = Date2LongSerializer.class)
    private LocalDateTime createTime;

    @JsonSerialize(using = Date2LongSerializer.class)
    private LocalDateTime updateTime;

    private List<OrderDetail> orderDetailList;

    @JsonIgnore
    public OrderStatusEnum getOrderStatusEnum() {
        return EnumUtil.getByCode(orderStatus, OrderStatusEnum.class);
    }

    @JsonIgnore
    public PayStatusEnum getPayStatusEnum() {
        return EnumUtil.getByCode(payStatus, PayStatusEnum.class);
    }
}
