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;
            }
        }
