我使用 iReport 设计了带有超链接功能的 jrxml 但它不起作用（报告正在显示，但超链接无效）。
我正在使用此 jsp 页面显示报告：

jasperPrint = net.sf.jasperreports.engine.JasperFillManager.fillReport(jasperReport, values, myJdbcTemplate.getDataSource().getConnection());

}
JRHtmlExporter exporter = new JRHtmlExporter();
int pageIndex = 0;
int lastPageIndex = 0;
if (jasperPrint.getPages() != null) {
lastPageIndex = jasperPrint.getPages().size() - 1;
}
String pageStr = request.getParameter("page");
System.out.println("page::" + pageStr);
try {
pageIndex = Integer.parseInt(pageStr);

我认为问题出在 jasperPrint 对象中。
请指导我如何添加超链接功能。
