iReport：如何根据法语区域设置格式化日期 [英] iReport: How to format date based on French locale

问题描述

我在 iReport中格式化日期有问题

我的电脑我将语言环境语言配置为法语但是当 iReport 生成报告时，我发现使用英语区域设置形成日期。

这里有几个我的 jrxml 文件中的代码：

 < band height = 41splitType =Stretch> 
< textField pattern =dd / MM / yyyy h.mm a> 
< reportElement uuid =fb711e77-c949-4a99-9b52-109aae00c8edx =87y =19width =100height =20/> 
< textElement /> 
< textFieldExpression><！[CDATA [$ P {datenow}]]>< / textFieldExpression> 
< / textField> 
< staticText> 
< reportElement uuid =51fb76a0-829e-4c36-b474-3ff9c7d4c239x =41y =19width =48height =20/> 
< textElement> 
< font isBold =trueisItalic =true/> 
< / textElement> 
< text><！[CDATA [Fes Le：]]>< / text> 
< / staticText> 
< / band> 
  

以下是我的显示方式： Fri Sep 28 09:59:00

我的目标格式是： vendredi 28 septembre 2012 09:59 （法语）

你有什么想法吗？

解决方案

您的问题重复参数。

  Map< String，Object> params = new HashMap< String，Object>（）; 
 params.put（JRParameter.REPORT_LOCALE，Locale.FRENCH）; 
 JasperFillManager.fillReportToFile（compiledReportName，params）; 
  

使用此代码生成的报告结果相同。

工作样本 jrxml 文件：

 <？xml version =1.0encoding =UTF-8？> 
< jasperReport ... whenNoDataType =AllSectionsNoDetail...> 
< parameter name =dateclass =java.util.DateisForPrompting =false> 
< defaultValueExpression><！[CDATA [new Date（）]]>< / defaultValueExpression> 
< /参数> 
< title> 
< band height =50> 
< textField pattern =EEEEE dd MMMMM yyyy> 
< reportElement x =200y =11width =228height =20/> 
< textElement /> 
< textFieldExpression><！[CDATA [$ P {date}]]>< / textFieldExpression> 
< / textField> 
< / band> 
< / title> 
< / jasperReport> 
  

Java代码：

  Map< String，Object> params = new HashMap< String，Object>（）; 
 params.put（date，new Date（））; 
 params.put（JRParameter.REPORT_LOCALE，Locale.FRENCH）; 
 
 JasperReport jasperReport = JasperCompileManager.compileReport（reportSource）; 
 JasperPrint jasperPrint = JasperFillManager.fillReport（jasperReport，params，connection）; 
 
 JasperExportManager.exportReportToPdfFile（jasperPrint，outputFile）; 
  

结果为：

I have a problem with formatting date in iReport

An my pc I configured the locale language as French but when the iReport generate the reports I find the date formated with English locale.

Here is a few code from my jrxml file :

<band height="41" splitType="Stretch">
    <textField pattern="dd/MM/yyyy h.mm a">
        <reportElement uuid="fb711e77-c949-4a99-9b52-109aae00c8ed" x="87" y="19" width="100" height="20"/>
        <textElement/>
        <textFieldExpression><![CDATA[$P{datenow}]]></textFieldExpression>
    </textField>
    <staticText>
        <reportElement uuid="51fb76a0-829e-4c36-b474-3ff9c7d4c239" x="41" y="19" width="48" height="20"/>
        <textElement>
            <font isBold="true" isItalic="true"/>
        </textElement>
        <text><![CDATA[Fes Le : ]]></text>
    </staticText>
</band>

and here is how it is displayed for me: Fri Sep 28 09:59:00

My target format is: vendredi 28 septembre 2012 09:59 (in French)

Do you have any idea?

解决方案

Your question duplicates How to change date format (month name) in iReport? and Setting REPORT_LOCALE in IReport? posts.

• For setting locale in iReport you should call dialog Options - Compilation and exectution (via iReport -> Tools -> Options menu).

For this textField:

<textField pattern="EEEEE dd MMMMM yyyy">
    <reportElement x="0" y="0" width="100" height="20"/>
    <textElement/>
    <textFieldExpression><![CDATA[$F{date}]]></textFieldExpression>
</textField>

The result will be:

Note: It's works only for preview in iReport.

• For Java application you can set JRParameter.REPORT_LOCALE parameter.

Map<String, Object> params = new HashMap<String, Object>(); 
params.put(JRParameter.REPORT_LOCALE, Locale.FRENCH); 
JasperFillManager.fillReportToFile(compiledReportName, params); 

The result will be the same for report generated with code like this.

The working sample, jrxml file:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport ...  whenNoDataType="AllSectionsNoDetail" ...>
    <parameter name="date" class="java.util.Date" isForPrompting="false">
        <defaultValueExpression><![CDATA[new Date()]]></defaultValueExpression>
    </parameter>
    <title>
        <band height="50">
            <textField pattern="EEEEE dd MMMMM yyyy">
                <reportElement x="200" y="11" width="228" height="20"/>
                <textElement/>
                <textFieldExpression><![CDATA[$P{date}]]></textFieldExpression>
            </textField>
        </band>
    </title>
</jasperReport>

Java code:

Map<String, Object> params = new HashMap<String, Object>();
params.put("date", new Date());
params.put(JRParameter.REPORT_LOCALE, Locale.FRENCH);

JasperReport jasperReport = JasperCompileManager.compileReport(reportSource);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, connection);

JasperExportManager.exportReportToPdfFile(jasperPrint, outputFile);

The result be:
