您有两个选项(我不是在考虑可以在customerJbean上创建方法):

定义一个字段,并在描述中指示属性的路径。

<field name="BillingAddress1" class="java.lang.String">
    <fieldDescription><![CDATA[billingAddress.address1]]></fieldDescription>
</field>

<field name="_THIS" class="com.your.package.CustomerJ"/>
<textField>
    <reportElement x="0" y="0" width="100" height="20" uuid="5884d3b9-3239-4d2e-af3e-ee5163da3d3b"/>
    <textFieldExpression><![CDATA[$F{_THIS}.getBillingAddress().getAddress1()]]></textFieldExpression>
</textField>
