### 一、场景 ###

需要根据编号动态给类设置值，属性名为“f+费用编号”，例如f01表示编号为01的费用

public class MonitorDayFee implements Serializable {
        private static final long serialVersionUID = 1L;
    
        private Long dayFeeId;//主键
    
        private String ordinalNo;//流水号
    
        private Integer collectYear;//统计年份
    
        private Integer collectMonth;//统计月份
    
        private Integer collectDay;//统计天
    
        private String deptId;//院科室ID
    
        private String deptName;//院科室名称
    
        private BigDecimal f01;//床位费
    
        private BigDecimal f02;//西药费
    
        private BigDecimal f03;//中药费
    
        private BigDecimal f04;//中成药
    
        private BigDecimal f05;//中草药
    
        private BigDecimal f06;//检查费
    
        private BigDecimal f07;//治疗费
    
        private BigDecimal f08;//放射费
    
        private BigDecimal f09;//手术费
    
        private BigDecimal f10;//化验费
    
        private BigDecimal f11;//输血费
    
        private BigDecimal f12;//输氧费
    
        private BigDecimal f13;//其它
    
        private BigDecimal f14;//麻醉费
    
        private BigDecimal f15;//材料费
    
        private BigDecimal f16;//特殊检查费
    
        private BigDecimal f17;//特殊治疗费
    
        public Long getDayFeeId() {
            return dayFeeId;
        }
    
        public void setDayFeeId(Long dayFeeId) {
            this.dayFeeId = dayFeeId;
        }
    
        public String getOrdinalNo() {
            return ordinalNo;
        }
    
        public void setOrdinalNo(String ordinalNo) {
            this.ordinalNo = ordinalNo;
        }
    
        public Integer getCollectYear() {
            return collectYear;
        }
    
        public void setCollectYear(Integer collectYear) {
            this.collectYear = collectYear;
        }
    
        public Integer getCollectMonth() {
            return collectMonth;
        }
    
        public void setCollectMonth(Integer collectMonth) {
            this.collectMonth = collectMonth;
        }
    
        public Integer getCollectDay() {
            return collectDay;
        }
    
        public void setCollectDay(Integer collectDay) {
            this.collectDay = collectDay;
        }
    
        public String getDeptId() {
            return deptId;
        }
    
        public void setDeptId(String deptId) {
            this.deptId = deptId;
        }
    
        public String getDeptName() {
            return deptName;
        }
    
        public void setDeptName(String deptName) {
            this.deptName = deptName;
        }
    
        public BigDecimal getF01() {
            return f01;
        }
    
        public void setF01(BigDecimal f01) {
            this.f01 = f01;
        }
    
        public BigDecimal getF02() {
            return f02;
        }
    
        public void setF02(BigDecimal f02) {
            this.f02 = f02;
        }
    
        public BigDecimal getF03() {
            return f03;
        }
    
        public void setF03(BigDecimal f03) {
            this.f03 = f03;
        }
    
        public BigDecimal getF04() {
            return f04;
        }
    
        public void setF04(BigDecimal f04) {
            this.f04 = f04;
        }
    
        public BigDecimal getF05() {
            return f05;
        }
    
        public void setF05(BigDecimal f05) {
            this.f05 = f05;
        }
    
        public BigDecimal getF06() {
            return f06;
        }
    
        public void setF06(BigDecimal f06) {
            this.f06 = f06;
        }
    
        public BigDecimal getF07() {
            return f07;
        }
    
        public void setF07(BigDecimal f07) {
            this.f07 = f07;
        }
    
        public BigDecimal getF08() {
            return f08;
        }
    
        public void setF08(BigDecimal f08) {
            this.f08 = f08;
        }
    
        public BigDecimal getF09() {
            return f09;
        }
    
        public void setF09(BigDecimal f09) {
            this.f09 = f09;
        }
    
        public BigDecimal getF10() {
            return f10;
        }
    
        public void setF10(BigDecimal f10) {
            this.f10 = f10;
        }
    
        public BigDecimal getF11() {
            return f11;
        }
    
        public void setF11(BigDecimal f11) {
            this.f11 = f11;
        }
    
        public BigDecimal getF12() {
            return f12;
        }
    
        public void setF12(BigDecimal f12) {
            this.f12 = f12;
        }
    
        public BigDecimal getF13() {
            return f13;
        }
    
        public void setF13(BigDecimal f13) {
            this.f13 = f13;
        }
    
        public BigDecimal getF14() {
            return f14;
        }
    
        public void setF14(BigDecimal f14) {
            this.f14 = f14;
        }
    
        public BigDecimal getF15() {
            return f15;
        }
    
        public void setF15(BigDecimal f15) {
            this.f15 = f15;
        }
    
        public BigDecimal getF16() {

        public BigDecimal getF17() {
            return f17;
        }
    
        public void setF17(BigDecimal f17) {
            this.f17 = f17;
        }
    }

### 二、计算值动态设置进对象 ###

获取编号拼接方法名“setF+编号”

monitorDayFee=this.addMonitorDayFeeItemFee(monitorDayFee,"F"+itemType.getItemTypeCode(),itemFee);

通过反射机制动态调用

private MonitorDayFee addMonitorDayFeeItemFee(MonitorDayFee monitorDayFee, String itemCode,BigDecimal itemFee) throws Exception{
            Class classZ=Class.forName("com.zhq.business.scheduled.model.MonitorDayFee");
            Method method=classZ.getMethod("set"+itemCode,BigDecimal.class);
            method.invoke(monitorDayFee, itemFee);
            return monitorDayFee;
        }
