如何根据货币代码在不同的单元格中设置不同的货币

Question

我正在尝试使用 Apache POI 在不同的单元格中设置不同的货币。

我有 JSON 数据：

{
    "data": {
        "shop1": [
            {
                "sku": "sku1",
                "quantity": 1,
                "sale": "100",
                "currency": "USD",
                "cost": 500
            },
            {
                "sku": "sku2",
                "quantity": 1,
                "sale": "100",
                "currency": "USD",
                "cost": 500
            }
        ],
        "shop2": [
            {
                "sku": "sku1",
                "quantity": 1,
                "sale": "100",
                "currency": "COP",
                "cost": 500
            }
        ]
    }
}

我想得到这样的结果（Excel 数据）：

shop	sku	quantity	sale	cost CNY
shop1	sku1	1	$100.00	¥500.00
shop1	sku2	1	$1,000,000.00	¥50,000,000.00
shop2	sku1	1	COP 100.00	¥500.00

我希望它根据 JSON data.shop1[0].currency 显示不同的货币符号，例如 CNY show ¥ 或 USD show $

所以我尝试了这个：

XSSFCellStyle currency = xssfWorkbook.createCellStyle();
currency.setDataFormat(7);

它失败了，它只显示¥。它似乎根据我的系统所在的位置（中国）解析货币。

然后我尝试了：

String symbol = Currency.getInstance("CNY").getSymbol();
currency.setDataFormat(xssfWorkbook.createDataFormat().getFormat("{SYMBOL}#,#0.00".replace("{SYMBOL}", symbol)));

当我使用CNY 时，似乎没问题：我得到¥123.0，但是当我使用USD 时，它失败了，因为Currency.getInstance("CNY").getSymbol(); 使用系统默认语言环境。

在 Excel 中，我可以通过右键单击单元格 -> 格式化单元格 -> 数字 -> 货币 -> 符号（选择）来设置符号。

如何在 Apache POI 中设置货币？

Answer 1

设置像£#,##0.00 这样的数据格式总是会导致用户定义的数据格式。如果您想使用Excel 货币数据格式，就像使用 Format cells -> Number -> Currency -> Symbol -> 选择，那么你需要知道Excel 在这种情况下存储了什么。这些货币数据格式使用$ 后跟货币符号以及方括号中的Windows Language Code Identifier (LCID) 进行存储。例如：[$£-809]。那是英镑£ 大不列颠及北爱尔兰联合王国LCID 809。

要从ISO 国家代码创建此类格式，需要一张将货币代码映射到Excel LCID 货币代码的地图。不幸的是，据我所知，没有这样的地图可用。所以我们需要从头开始创建它。为此，请创建具有此类货币值的 Excel *.xlsx。然后解压缩*.xlsx（它只是一个ZIP 存档）并查看/xl/styles.xml。在那里你会找到类似的东西：

<numFmts count="6">
 <numFmt formatCode="[$$-409]#,##0.00" numFmtId="164"/>
 <numFmt formatCode="[$€-407]#,##0.00" numFmtId="165"/>
 <numFmt formatCode="[$¥-804]#,##0.00" numFmtId="166"/>
 <numFmt formatCode="[$₽-419]#,##0.00" numFmtId="167"/>
 <numFmt formatCode="[$£-809]#,##0.00" numFmtId="168"/>
 <numFmt formatCode="[$₺-41F]#,##0.00" numFmtId="169"/>
</numFmts>

使用这些信息，我们可以创建以下地图：

static final Map<String, String> currencyCodesExcelLCID = new HashMap<>() {
 {
  put("USD", "[$\u0024-409]");  //[$$-409]
  put("CNY", "[$\u00A5-804]");  //[$¥-804]
  put("EUR", "[$\u20AC-407]");  //[$€-407]
  put("RUB", "[$\u20BD-419]");  //[$₽-419]
  put("GBP", "[$\u00A3-809]");  //[$£-809]
  put("TRY", "[$\u20BA-41F]");  //[$₺-41F]
 }
};

在创建Excel 单元格时，我们可以使用该映射来获取单元格数据格式所需的LCID 货币代码。

完整示例：

import java.io.FileOutputStream;

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.ss.util.CellUtil;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;

import java.util.Map;
import java.util.HashMap;

public class CreateExcelDifferentCurrencies {

 static final Map<String, String> currencyCodesExcelLCID = new HashMap<>() {
  {
   put("USD", "[$\u0024-409]");  //[$$-409]
   put("CNY", "[$\u00A5-804]");  //[$¥-804]
   put("EUR", "[$\u20AC-407]");  //[$€-407]
   put("RUB", "[$\u20BD-419]");  //[$₽-419]
   put("GBP", "[$\u00A3-809]");  //[$£-809]
   put("TRY", "[$\u20BA-41F]");  //[$₺-41F]
  }
 };

 public static void main(String[] args) throws Exception {

  Object[][] data = {
   {"Name", "Code", "Value"},
   {"US Dollar", "USD", 1234.56d},
   {"Euro (Germany)", "EUR", 1234.56d},
   {"Yuan Renminbi", "CNY", 1234.56d},
   {"Russian Ruble", "RUB", 1234.56d},
   {"Pound Sterling", "GBP", 1234.56d},
   {"Turkish Lira", "TRY", 1234.56d},
   {"Not available", "NA", 1234.56d}
  };

  XSSFWorkbook workbook = new XSSFWorkbook(); String filePath = "./CreateExcelDifferentCurrencies.xlsx";
  //HSSFWorkbook workbook = new HSSFWorkbook(); String filePath = "./CreateExcelDifferentCurrencies.xls";

  DataFormat dataFormat = workbook.createDataFormat();

  Sheet sheet = workbook.createSheet();

  for (int r = 0; r < data.length; r++) {
   Object[] dataRow = data[r];
   Row row = sheet.createRow(r);
   String currencyCode = "";
   for (int c = 0; c < dataRow.length; c++) {   
    Object value = dataRow[c];
    Cell cell = row.createCell(c);
    if (value instanceof String) {
     cell.setCellValue((String)value);
     if (c == 1) currencyCode = (String)value;
    } else if (value instanceof Double) {
     cell.setCellValue((Double)value);
     String symbolLCID = currencyCodesExcelLCID.getOrDefault(currencyCode, "");
     CellUtil.setCellStyleProperty(cell, CellUtil.DATA_FORMAT, dataFormat.getFormat(symbolLCID + "#,##0.00"));
    }
   }
  }

  for (int c = 0; c < data[0].length; c++) {
   sheet.autoSizeColumn(c);
  }

  FileOutputStream out = new FileOutputStream(filePath);
  workbook.write(out);
  out.close();
  workbook.close();
 }
}

Answer 2

在您的情况下，最可靠的解决方案是映射 CODE -> SYMBOL。 只需将Currency.getInstance("CNY").getSymbol(); 替换为codeSymbolMap.get("CNY")。
