Jasper报告不包括JRScriptlet？

Question

这是我的代码：

 public void makeReportAddToPanel()
   {


       JasperReportBuilder report = DynamicReports.report();//a new report

       report
          .columns(
              Columns.column("Applicant", "ApplicantName", DataTypes.stringType()),
              Columns.column("Quiz", "Quiz", DataTypes.integerType()),
              Columns.column("Score", "Score", DataTypes.integerType()))
                .title(//title of the report
              Components.text("Score Per Quiz")
              .setHorizontalAlignment(HorizontalAlignment.CENTER))
              .pageFooter(Components.pageXofY())//show page number on the page footer
              .setDataSource("Select answer,userId,questionId from quizTaken",dao.Connection.getDBConnection());

        try {
                    //show the report
            JRViewer view = new JRViewer(report.toJasperPrint());
            report.show();
            this.add(view);

                    //export the report to a pdf file
            report.toPdf(new FileOutputStream("/report.pdf"));
        } catch (DRException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
      }

这是堆栈跟踪

因此，我试图构建报告并将其放入面板中，但是当我运行代码时，出现此错误...当我查看jasperreport jar时，不包括JRScriptlet软件包

Answer 1

您的项目缺少依赖项。

因此，您必须将jasperreport-xxx.jar（其中xxx对应于您的目标版本）添加到类路径中。

如果您使用的是maven，请将GAV参数添加到具有适当范围的pom.xml文件中（默认情况下进行编译）。
