枚举：常用的方法
通过实体类直接调用– 例子：
HTradeOnlineMerchantOrder.orderTypeEnum .getNameByCode(nCode);

public enum orderTypeEnum {
        Online(1, "线上订单"), BelowTheLine(2, "线下订单") ;
        private int nCode;
        private String name;
        private orderTypeEnum(int _nCode, String _name) {
            this.nCode = _nCode;
            this.name = _name;
        }
        public int getCode() {
            return this.nCode;
        }
        public static String getNameByCode(int nCode) {
            for (HTradeOnlineMerchantOrder.orderTypeEnum c : HTradeOnlineMerchantOrder.orderTypeEnum.values()) {
                if (c.getCode() == nCode) {
                    return c.name;
                }
            }
            return null;
        }
    }
    public enum statusEnum {
        //订单的状态 0=未支付 1= 支付中 2= 已支付 3=未发货 4= 已发货
        Unpaid("NO_PAY", "未支付"), Payment("Payment", "支付中"),AlreadyPaid("SUCC_REFUND", "已支付"), NotShipped("NotShipped", "未发货") , Shipped("Shipped", "已发货");
        private String nCode;
        private String name;
        private statusEnum(String _nCode, String _name) {
            this.nCode = _nCode;
            this.name = _name;
        }
        public String getCode() {
            return this.nCode;
        }
        public String getName() {
            return this.name;
        }
        public static String getNameByCode(String nCode) {
            for (HTradeOnlineMerchantOrder.statusEnum c : HTradeOnlineMerchantOrder.statusEnum.values()) {
                if (c.getCode().equals(nCode)) {
                    return c.name;
                }
            }
            return null;
        }
    }
