Answer 1

您已将amount字段作为字符串。

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

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>

您需要将Amount和TotalAmount变量设为Integer，以便jasper报告能够计算总和。因此将其改为以下：

<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，则将其转换为Integer，然后提供给jasper报告。

报告中的总计
