将数字转换为本地（UTF8）JasperReports中的孟加拉语数字& MySQL的 [英] Converting Numbers to Local (UTF8) Bengali numbers in JasperReports & MySQL
本文介绍了将数字转换为本地（UTF8）JasperReports中的孟加拉语数字& MySQL的的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想在填写报告之前将英文数字转换为孟加拉语。我从MySQL获得的数据：
I am trying to convert the English numbers to Bengali numbers before filling the report. The data i am getting from MySQL:
SELECT brand.id,brand.brand,model.model FROM brand INNER JOIN model ON brand.id=model.id AND model.id=$P{ID}
例如if model .model列返回一个数字322然后它应该首先将数字转换为孟加拉语版本（3২২）然后它将填充报告。这样的事情：
For example if model.model columns return a number 322 then it should first convert the number to Bengali version(৩২২) and then it will fill the report.Something like this:
一个|两个|三个
1 | ২| 3
One | two | Three ১ | ২ | ৩
这是孟加拉语中的0-9：
Here is the 0-9 in Bengali:
0 1২3 4 5 6 7 8 9
০ ১ ২ ৩ ৪ ৫ ৬ ৭ ৮ ৯
我在考虑如下替换方法：
I was thinking about replace method as follows:
char[] en ={'0','1','2','3','4','5','6','7','8','9'};
char[] bn ={'০','১','২','৩','৪','৫','৬','৭','৮','৯'};
en.replace(bn)
也许它不起作用！
我不知道从哪里开始！但这是我目前的申请代码：
I am just not sure where to start ! But here is my current Application Codes:
Java代码：
@FXML
public TextField one;
public void click(ActionEvent event) throws JRException, SQLException, ClassNotFoundException, IllegalAccessException, UnsupportedLookAndFeelException, InstantiationException {
String reportSrcFile = "/home/sample/learn.jrxml";
JasperReport jasperReport1 = JasperCompileManager.compileReport(reportSrcFile);
Connection conn = SqliConnect.getMySQLConnection();
int two = Integer.parseInt(one.getText());
Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("ID",one.getText());
JasperPrint print = JasperFillManager.fillReport(jasperReport1,
parameters, conn);
JasperViewer jv = new JasperViewer(print);
jv.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jv.setTitle("Test Report");
jv.setVisible(true);
}

这样做的正确方法是什么？
What is the Right way to do it?
推荐答案
您还可以在Java代码中创建替换字符串并在参数映射中使用它：
You also could create a replacement String in the Java code and use it in the parameters map:
String replacedOne = one.getText().replaceAll("0","০").replaceAll("1","১").replaceAll("2","২").replaceAll("3","৩").replaceAll("4","৪").replaceAll("5","৫").replaceAll("6","৬").replaceAll("7","৭").replaceAll("8","৮").replaceAll("9","৯");
parameters.put("replacedID",replacedOne);
或者更好，你可以直接在你的jrxml文件中执行替换，而不需要修改java文件，使用此（非常长）表达式而不是$ F {model}：
Or better, you can perform the replacement directly in your jrxml file, with no need to modify the java file, by using this (very long) expression instead of $F{model}:
$F{model}.replaceAll("0","০").replaceAll("1","১").replaceAll("2","২").replaceAll("3","৩").replaceAll("4","৪").replaceAll("5","৫").replaceAll("6","৬").replaceAll("7","৭").replaceAll("8","৮").replaceAll("9","৯");
