4. 代码实战
首先我们在function包下创建text包在text包下创建RmbCapFunction类代码如下
package com.ql.util.express.self.combat.function.text;import com.ql.util.express.Operator;
import com.ql.util.express.exception.QLException;
import com.ql.util.express.self.combat.helper.RmbCapConverter;import java.math.BigDecimal;/*** 类描述: RMBCAP函数** author admin* version 1.0.0* date 2023/11/24 15:00*/
public class RmbCapFunction extends Operator {public RmbCapFunction(String name) {this.name name;}Overridepublic Object executeInner(Object[] list) throws Exception {String rst ;if (list.length 0) {throw new QLException(操作数异常);} else if (list.length ! 1) {throw new QLException(操作数个数异常);} else {//数字Object num list[0];BigDecimal numB new BigDecimal(num.toString());double numD numB.doubleValue();rst RmbCapConverter.convertToRmbCap(numD);}return rst;}
}
在combat文件夹下创建工具包helper在helper包中创建RmbCapConverter类
package com.ql.util.express.self.combat.helper;import java.math.BigDecimal;/*** 类描述: RmbCapConverter工具类** author admin* version 1.0.0* date 2023/11/24 15:02*/
public class RmbCapConverter {private static final String[] RMB_UNIT {, 拾, 佰, 仟, 万, 拾, 佰, 仟, 亿,拾,佰,仟};private static final String[] RMB_DIGIT {零, 壹, 贰, 叁, 肆, 伍, 陆, 柒, 捌, 玖};public static String convertToRmbCap(double amount) {BigDecimal bd new BigDecimal(amount);String rmbCap ;// 判断金额正负if (bd.compareTo(BigDecimal.ZERO) 0) {rmbCap 负;bd bd.abs(); // 取绝对值}String rmbStr bd.setScale(2, BigDecimal.ROUND_HALF_UP).toPlainString();int dotPos rmbStr.indexOf(.);String integerPart dotPos -1 ? rmbStr : rmbStr.substring(0, dotPos);String decimalPart dotPos -1 ? : rmbStr.substring(dotPos 1);rmbCap translateIntegerPart(integerPart);rmbCap translateDecimalPart(decimalPart);return rmbCap;}private static String translateIntegerPart(String integerPart) {// 移除整数部分的前导零integerPart integerPart.replaceFirst(^0, );if (integerPart.equals()) {return RMB_DIGIT[0];}StringBuilder rmbCap new StringBuilder();int digitCount integerPart.length();int unitIndex digitCount - 1;boolean zeroFlag false;for (int i 0; i digitCount; i) {int digit integerPart.charAt(i) - 0;if (digit 0) {zeroFlag true;} else {if (zeroFlag) {rmbCap.append(RMB_DIGIT[0]);}zeroFlag false;rmbCap.append(RMB_DIGIT[digit]).append(RMB_UNIT[unitIndex]);}unitIndex--;}return rmbCap.toString()元;}private static String translateDecimalPart(String decimalPart) {if (decimalPart.equals() || decimalPart.equals(00)) {return ;} else {int digit1 decimalPart.charAt(0) - 0;int digit2 decimalPart.charAt(1) - 0;StringBuilder rmbCap new StringBuilder();if (digit1 ! 0) {rmbCap.append(RMB_DIGIT[digit1]).append(角);}if (digit2 ! 0) {rmbCap.append(RMB_DIGIT[digit2]).append(分);}return rmbCap.toString();}}
}
把RmbCapFunction类注册到公式函数入口类中代码如下
