枚举小例子记录

1、创建枚举类：

package com.atguigu.common.constant;

public class ProductConstant {

    public enum AttrEnum {

        ATTR_TYPE_BASE(1, "基本属性"), ATTR_TYPE_SALE(0, "销售属性");

        private int code;
        private String msg;

        AttrEnum(int code, String msg) {
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public void setCode(int code) {
            this.code = code;
        }

        public String getMsg() {
            return msg;
        }

        public void setMsg(String msg) {
            this.msg = msg;
        }
    }
}

2、使用枚举：

if(attr.getAttrType() == ProductConstant.AttrEnum.ATTR_TYPE_BASE.getCode()) {
     　 ...
}
