Question

我们有一个内部遗留Java库，用jasper + spring生成报告，并将它们导出为html，pdf或xls。但是，excel文件具有相同（无）格式的所有单元格我们有一个报告，其中一列填充了文本，并且担心它可以被解释为带有数值或其他类型代码的公式。同样，我们有一些前导零的字符串应该出现在报告中。我尝试通过jasperExportParameters将JExcelApiExporterParameter.IS_DETECT_CELL_TYPE设置为true。

报告配置通过xml完成，如下所示：

<bean id="jasperReportHeader" class="java.lang.String">
    <constructor-arg>
        <value>
        <![CDATA[
            <html>
        ]]>
        </value>
    </constructor-arg>
</bean>

<bean id="jasperExportParameters" class="java.util.HashMap">
    <constructor-arg>
        <map>
            <entry
                  key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN"
                value="false" />
            <entry
                key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IMAGES_URI">
                <value><![CDATA[utils.jasper?opcion=muestraImagen&image=]]></value>
            </entry>
            <entry
                key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.HTML_HEADER">
                <ref bean="jasperReportHeader" />
            </entry>
            <entry
                key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.HTML_FOOTER">
                <ref bean="jasperReportFooter" />
            </entry>
            <entry
                key="net.sf.jasperreports.engine.export.JRCsvExporterParameter.FIELD_DELIMITER"
                value="|" />
            <entry
                key="net.sf.jasperreports.engine.export.JExcelApiExporterParameter.IS_DETECT_CELL_TYPE"
                value="true" />
        </map>
    </constructor-arg>
</bean>

<bean id="jasperReportFooter" class="java.lang.String">
    <constructor-arg>
        <value>
        <![CDATA[
      </html>
        ]]>
        </value>
    </constructor-arg>
</bean>

<!-- REPORTES -->

<bean id="solicitudRevisionView"
    class="mx.org.rfe.ife.siirfe.comun.web.spring.views.jasper.CustomJasperReportsMultiFormatView">
    <property name="url" value="/WEB-INF/reportes/SOLICITUD_REVISION.jasper" />
    <property name="exporterParameters" ref="jasperExportParameters" />
</bean>

如何告诉jasper格式化文本格式的单元格？它可以吗？

这个库正在使用jasper 4.6.0，但如果需要，我可以迁移。我们的报告已使用iReport 3.7.6进行编辑。

Jasperreports won't interpret your cells to be formulas unless you tell it that they are so. On the other hand, I guess your exporter parameters are not set properly with the map declaration fed into CustomJasperReportsMultiFormatView. Instead of the map declaration, I'd expect something more like

<bean id="solicitudRevisionView"
class="mx.org.rfe.ife.siirfe.comun.web.spring.views.jasper.CustomJasperReportsMultiFormatView">
<property name="url" value="/WEB-INF/reportes/SOLICITUD_REVISION.jasper" />
<property name="exporterParameters">
 <props>
   <prop name="net.sf.jasperreports.export.xls.detect.cell.type">true</prop>
 </props>
</property>

as the Java constants in your spring xml configuration file, like net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, won't be evaluated unless you do it in a different way.
