Thymeleaf金额变汉字大写

可以使用Thymeleaf的内置工具类来实现将金额转换为汉字大写。以下是一个示例:
在你的Thymeleaf模板中,可以使用以下代码:
```
<p th:text="${#numbers.formatDecimal(amount, 2, 'COMMA')}"></p>
<p th:text="${T(com.example.utils.MoneyUtils).toChinese(amount)}"></p>
```
其中,`amount`是要转换为汉字大写的金额值。第一个`p`标签是用来显示原始金额值的,第二个`p`标签则使用了自定义的工具类`MoneyUtils`来将金额转换为汉字大写。
然后,你需要创建一个名为`MoneyUtils`的Java类,该类包含一个静态方法`toChinese`,用于将金额值转换为汉字大写。以下是一个可能的实现:
```java
package com.example.utils;
public class MoneyUtils {
private static final String[] CN_NUM = {"零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"};
private static final String[] CN_UNIT = {"", "拾", "佰", "仟", "万", "拾", "佰", "仟", "亿", "拾", "佰", "仟"};
public static String toChinese(double amount) {
if (amount > 99999999999999.99 || amount < -99999999999999.99) {
throw new IllegalArgumentException("金额超出范围!");
}
boolean negative = false;
if (amount < 0) {
negative = true;
amount = -amount;
}
// 将金额转换为字符串,并分别取整数部分和小数部分
String amountStr = String.format("%.2f", amount);
String integerPart = amountStr.substring(0, amountStr.indexOf('.'));
String decimalPart = amountStr.substring(amountStr.indexOf('.') + 1);
// 将整数部分转换为汉字大写字符串
StringBuilder integerStr = new StringBuilder();
int numLen = integerPart.length();
for (int i = 0; i < numLen; i++) {
int digit = integerPart.charAt(i) - '0';
int unitLen = 11 - i;
if (digit != 0) {
integerStr.append(CN_NUM[digit]).append(CN_UNIT[unitLen - 1]);
} else {
// 在汉字字符串中,如果当前数字是0,则需要判断前面是否已经有过数字
// 如果前面已经有过数字,则只需要添加一个“零”,否则不需要添加
if (i == numLen - 1 || integerStr.charAt(integerStr.length() - 1) != '零') {
integerStr.append(CN_NUM[digit]);
}
}
}
// 处理小数部分
StringBuilder decimalStr = new StringBuilder();
int decimalLen = decimalPart.length();
for (int i = 0; i < decimalLen; i++) {
int digit = decimalPart.charAt(i) - '0';
if (digit != 0) {
decimalStr.append(CN_NUM[digit]).append(CN_UNIT[i + 1]);
}
}
// 拼接汉字字符串
StringBuilder result = new StringBuilder();
if (negative) {
result.append("负");
}
result.append(integerStr.toString());
if (decimalStr.length() != 0) {
result.append("点").append(decimalStr.toString());
}
return result.toString();
}
}
```
在这个示例中,我们首先将金额值转换为字符串,并分别取整数部分和小数部分。然后,我们将整数部分转换为汉字大写字符串,处理小数部分,最后将它们拼接起来并返回结果。
需要注意的是,该示例中只能处理到万亿级别的金额,如果需要处理更大的金额,需要修改相关代码。
