如何使用Velocity的NumberTool大货币数量 [英] How to use Velocity NumberTool for big currency numbers
问题描述
我在我的项目中使用Joda Money.class作为货币。
我使用NumberTool格式化Velocity模板中的数字。
context.put(number,new NumberTool());
我将Money值转换为整数,以便将这些值放入Velocity模板中。
$ b
例子:
// 123435€1234.35
priceInCents = price.getAmountMinorInt( );
我想在Velocity模板中格式化这个值,如下所示:
1.234,35
我试过以下情况: number.format('#0,00',$ price)//输出:1234,35
$ number.format('#0.00',$ price)//输出:123435.00
$ number。格式('#00,00',$ price)//输出:12,34,35
$ number.format('#00.00',$ price)//输出:123435.00
$数字。格式('#000,00',$ price)//输出:12,34,35
$ number.format('#000.00',$ price)//输出:123435.00
所以我找到了我的答案。
制作您自己的工具
context.put(currency,new CurrencyTool ));
用法:
$ currency.format($ price)
基本创建工具:
/ **
*进行货币格式化的工具
* /
@DefaultKey(value =currency )
public final class CurrencyTool extends FormatConfig {
$ b / **
*构造函数
* /
public CurrencyTool(){
}
$ b / **
* @param money用于格式化
* @return
* /
的{@link Money对象public String format(Money钱){
//获取货币作为整数
final int value = money.getAmountMinorInt();
//确定单位和美分
final int cents = value%100;
String units =+(value / 100);
//最终格式化的值
String formattedCents =;
String formattedUnits =;
//将美分格式化为2位十进制数
formattedCents =美分< 10? 0+分:+分;
//将单位格式化为以点分隔的部分3
if(units.length()> 3){
//单位高于999,需要格式
//确定不需要分割的零件的长度
//示例:12 12345234(12.345.234)
final int nonSegment =单位。长度()%3;
formattedUnits = units.substring(0,nonSegment);
//为每个段放置一个点
//例如:nonSegment(点)345(点)234
units = units.substring(nonSegment,units.length() );
for(String segment:units.split((?< = \\G ...))){
formattedUnits = formattedUnits +。 +细分;
}
} else {
//单位低于1000,不需要格式
formattedUnits = units;
}
返回formattedUnits +,+ formattedCents;
}
}
I'm using the Joda Money.class for currency in my project.
I'm using the NumberTool for formatting numbers inside a Velocity template.
context.put("number", new NumberTool());
I convert Money values into ints for placing these values inside a Velocity template.
example:
// 123435 €1234.35
priceInCents = price.getAmountMinorInt();
I want to format this value inside the Velocity template as below:
1.234,35
How do I accomplish this?
I tried the following cases:
$number.format('#0,00', $price) //Output: 1234,35
$number.format('#0.00', $price) //Output: 123435.00
$number.format('#00,00', $price) //Output: 12,34,35
$number.format('#00.00', $price) //Output: 123435.00
$number.format('#000,00', $price) //Output: 12,34,35
$number.format('#000.00', $price) //Output: 123435.00
So I found my answer. Make your own tool
context.put("currency", new CurrencyTool());
Usage:
$currency.format($price)
Basics created tool:
/**
* Tool for doing currency formatting
*/
@DefaultKey(value = "currency")
public final class CurrencyTool extends FormatConfig {
/**
* Constructor
*/
public CurrencyTool() {
}
/**
* @param money The {@link Money} object to format
* @return
*/
public String format(Money money) {
// Get the currency as an integer
final int value = money.getAmountMinorInt();
// Determine the units and cents
final int cents = value % 100;
String units = "" + (value / 100);
// Final formatted values
String formattedCents = "";
String formattedUnits = "";
// Format the cents to a 2 decimal number
formattedCents = cents < 10 ? "0" + cents : "" + cents;
// Format the units to parts of 3 separated with a dot
if (units.length() > 3) {
// units is above 999, formatting required
//Determine the length of the part that doesn't needs to be segmented
//example: 12 of 12345234 (12.345.234)
final int nonSegment = units.length() % 3;
formattedUnits = units.substring(0, nonSegment);
//place a dot for each segment
//example: nonSegment (dot) 345 (dot) 234
units = units.substring(nonSegment, units.length());
for (String segment : units.split("(?<=\\G...)")) {
formattedUnits = formattedUnits + "." + segment;
}
} else {
// units is below 1000, no formatting required
formattedUnits = units;
}
return formattedUnits + "," + formattedCents;
}
}
