Question

jasperreports-server中的示例报表是怎么制作的

Answer 1

下面的代码（JasperReportExport.java）演示了JasperReport文档的导出过程。该JasperExportManager提供的方法将报表导出成PDF，HTML和XML。导出到使用的类net.sf.jasperreports.engine.export.JRXlsExporter的XLS格式。此代码生成以下三个文件：

· sample_report.pdf

· sample_report.htmll

· sample_report.xls

导出为其他格式

让我们来写一个报表模板。在JRXML文件的内容 (C:\tools\jasperreports-5.0.1\test\jasper_report_template.jrxml) 如下:

<queryString>

<![CDATA[]]>

</queryString>

<fieldname="country"class="java.lang.String">

<fieldDescription><![CDATA[country]]></fieldDescription>

</field>

<fieldname="name"class="java.lang.String">

<fieldDescription><![CDATA[name]]></fieldDescription>

</field>

<columnHeader>

<bandheight="23">

<staticText>

<reportElementmode="Opaque"x="0"y="3"width="535"

height="15"backcolor="#70A9A9"/>

<box>

<bottomPenlineWidth="1.0"lineColor="#CCCCCC"/>

</box>

<textElement/>

<text><![CDATA[]]> </text>

</staticText>

<staticText>

<reportElementx="414"y="3"width="121"height="15"/>

<textElementtextAlignment="Center"

verticalAlignment="Middle">

<fontisBold="true"/>

</textElement>

<text><![CDATA[Country]]></text>

</staticText>

<staticText>

<reportElementx="0"y="3"width="136"height="15"/>

<textElementtextAlignment="Center"

verticalAlignment="Middle">

<fontisBold="true"/>

</textElement>

<text><![CDATA[Name]]></text>

</staticText>

</band>

</columnHeader>

<detail>

<bandheight="16">

<staticText>

<reportElementmode="Opaque"x="0"y="0"width="535"

height="14"backcolor="#E5ECF9"/>

<box>

<bottomPenlineWidth="0.25"lineColor="#CCCCCC"/>

</box>

<textElement/>

<text><![CDATA[]]> </text>

</staticText>

<textField>

<reportElementx="414"y="0"width="121"height="15"/>

<textElementtextAlignment="Center"

verticalAlignment="Middle">

<fontsize="9"/>

</textElement>

<textFieldExpressionclass="java.lang.String">

<![CDATA[$F{country}]]>

</textFieldExpression>

</textField>

<textField>

<reportElementx="0"y="0"width="136"height="15"/>

<textElementtextAlignment="Center"

verticalAlignment="Middle"/>

<textFieldExpressionclass="java.lang.String">

<![CDATA[$F{name}]]>

</textFieldExpression>

</textField>

</band>

</detail>

</jasperReport>

问件C:\tools\jasperreports-5.0.1\test\src\com\yiibai\DataBeanList.java 的内容如下：

package com.yiibai;

import java.util.ArrayList;

publicclassDataBeanList{

publicArrayList<DataBean> getDataBeanList(){

ArrayList<DataBean> dataBeanList =newArrayList<DataBean>();

dataBeanList.add(produce("Manisha","India"));

dataBeanList.add(produce("Dennis Ritchie","USA"));

dataBeanList.add(produce("V.Anand","India"));

dataBeanList.add(produce("Shrinath","California"));

return dataBeanList;

}
