我点击了此处的链接，将其与sprint启动应用程序集成
运行应用程序和空白报告时出现以下错误。
Pleasssssssse帮助我集成了从工作室生成的报告到春季启动。
（我是Java新手）
这是我的报告控制器方法
@RequestMapping( method = RequestMethod.GET)
public void report(HttpServletResponse response) throws Exception {
response.setContentType("text/html");
JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(userReportService.report());
InputStream inputStream = this.getClass().getResourceAsStream("/reports/users_report.jrxml");
JasperReport jasperReport = JasperCompileManager.compileReport(inputStream);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, dataSource);
HtmlExporter exporter = new HtmlExporter(DefaultJasperReportsContext.getInstance());
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleHtmlExporterOutput(response.getWriter()));
exporter.exportReport();
}
正在传递json数据作为数据源
1 个解决方案

我在这个stackoverflow问题中找到了解决方案，答案中突出显示的步骤是：
- 从服务器发送数据源作为参数，并在报告中填充另一个（可以为空）。
- 在类型为JRBeanCollectionDataSource的报告中声明一个新参数
- 将TableDatasource设置为使用$ P {DS1}参数。
- ...
另外，我修改了报告文件字段声明，并删除了那里的所有jasper studio属性。
在执行了此步骤并修改了我的报告文件和控制器后，它开始工作了。 这是我的新控制器方法：
public void report(HttpServletResponse response) throws Exception {
response.setContentType("text/html");
List data = userReportService.report();
JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(data);
Map parameters = new HashMap();
parameters.put("test", data.get(0));
parameters.put("DS1", dataSource);
InputStream inputStream = this.getClass().getResourceAsStream("/reports/users_report.jrxml");
JasperReport jasperReport = JasperCompileManager.compileReport(inputStream);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
HtmlExporter exporter = new HtmlExporter(DefaultJasperReportsContext.getInstance());
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleHtmlExporterOutput(response.getWriter()));
exporter.exportReport();
}
我的新jrxml文件是这样的：
