[如何在Jaspersoft iReport Designer中对列中的所有值进行求和？]（http://stackoverflow.com/questions/13550514/how-to-sum-all-values -in-a-column-in-jaspersoft-ireport-designer） – 2016-07-15 19:51:17

您已将amount字段视为字符串。

<field name="Amount" class="java.lang.String"/>

而你的变量类型也是字符串。

<variable name="TotalAmount" class="java.lang.String" calculation="Sum"> 
     <variableExpression><![CDATA[$F{Amount}]]></variableExpression> 
    </variable>

你需要有Amount和TotalAmount变量是整数，以便碧玉报告能够计算的总和。因此，将其更改为以下：

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

和

<variable name="TotalAmount" class="java.lang.Integer" calculation="Sum"> 
     <variableExpression><![CDATA[$F{Amount}]]></variableExpression> 
    </variable>

Note :如果Amount已经String然后将其转换为Integer再喂到碧玉报告。
