Question

我正在尝试将D3js与我们的jasper报告集成，当我从jasper工作室运行时，带有d3图表的报告正常工作。但是当从spring应用程序执行时，jasper报告无法加载JavaScript文件。

我现在要做的是将文件作为输入流放在参数

中

parameters.put("res_js_Page2_cell3",cacheService.getJasperInputStream("d3charts/Page2_pie/d3_piechart.min.js"));

报告中：

<cvc:itemProperty name="script">
       <valueExpression><![CDATA[$P{res_js_Page2_cell3}]]></valueExpression>
</cvc:itemProperty>

错误：
