Question

我在表格的单元格中使用Jasper内置SUM函数。它应该总结其他单元格的内容（在示例中我使用单个单元格，但输出几乎相同添加多个单元格。）

jrxml是：

<jr:column width="49" uuid="e6595bc8-b46e-4bbe-85a2-7ea9526fce83">
 <property name="local_mesure_unitwidth" value="pixel"/>
  <jr:columnHeader style="Table 2_CH" height="20">
    <staticText>
     <reportElement x="2" y="0" width="47" height="20" uuid="af5e8305-5cdf-41ad-b827-80f0ca14771c"/>
     <textElement textAlignment="Center" verticalAlignment="Middle"/>
     <text><![CDATA[Nr. Prest.]]></text>
    </staticText>
  </jr:columnHeader>
  <jr:detailCell style="Table 2_TD" height="30">
   <textField>
    <reportElement x="0" y="0" width="49" height="30" uuid="8cc69012-6972-470a-92f4-e735f8d006d8"/>
    <textFieldExpression><![CDATA[SUM($F{1})]]></textFieldExpression>
   </textField>
  </jr:detailCell>
</jr:column>

在Jasper Studio中工作正常，但是当我尝试使用maven插件或使用JasperCompileManager编译报表时，它会返回这些错误

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file:

net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:204)
net.sf.jasperreports.engine.JasperCompileManager.compile(JasperCompileManager.java:241)

我升级到最新的Jasper版本（5.5.0）但结果是一样的。

Answer 1

变化

<field name="1" class="java.lang.Integer"/>

到

<field name="one" class="java.lang.Integer"/>

并将表达式指定为

<textFieldExpression><![CDATA[SUM($F{one})]]></textFieldExpression>

Answer 2

我解决了将报告语言从Java更改为Javascript的编译问题：

<jasperReport ... name="report_name" language="javascript" ...>
