我刚刚尝试了 Jasper Report,我正在关注这个网站的教程
我还下载了示例源然后运行它并且没有错误。但是当我使用创建自己的报告时iReport
,对其进行编译,然后将.jasper
文件添加到我的项目中。当exception
我运行我的程序时:

这是我用于显示报告的按钮操作(这只是示例,报告仅包含一个带有参数的文本:outputText):
Map params = new HashMap();
params.put("outputText", "Hello world");
try {
JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("report2.jasper"), params, new JREmptyDataSource());
JasperViewer jv = new JasperViewer(printer);
jv.show();
} catch (JRException ex) {
ex.printStackTrace();
}
如果有dependency
问题,我已经将所有需要的 jar 导入到我的项目中,当我使用.jasper
该教程中的文件时没有问题,是因为版本不同iReport
吗?
