前台传入weightCode :1/2/3/4,获取不同的区间 0~1010~5050~100100~9999990~999999

 

public void setWeight(){        this.minWeight = FuelWeight.getFuelWeight(this.weightCode).minWeight;        this.maxWeight = FuelWeight.getFuelWeight(this.weightCode).maxWeight;    }    enum FuelWeight{        weightCode_1(1,0,10),        weightCode_2(2,10,50),        weightCode_3(3,50,100),        weightCode_4(4,100,999999),        weightCode_5(5,0,999999);        private Integer code;        private Integer minWeight;        private Integer maxWeight;        FuelWeight(Integer code, Integer minWeight,Integer maxWeight) {            this.code = code;            this.minWeight = minWeight;            this.maxWeight = maxWeight;        }        public static FuelWeight getFuelWeight(Integer code) {            for (FuelWeight weight : FuelWeight.values()) {                if (weight.code.equals(code))                    return weight;            }            return weightCode_5;        }    }
