Question

我制作了一个包含使用JasperSoft Studio的子报表的jasper报告。当我在工作室中预览时，它工作正常。但是当我将它添加到我的java fx项目中时，我必须将子报告作为参数发送到主报告中吗？

当我这样做时，我继续收到错误消息，指出未找到子报告资源。我不认为有任何拼写错误，因为我几乎所有包含子报告的报告都试过这个...仍然继续得到错误..

这些是我尝试的东西 1.使用jaspersoft studio再次编译报告，并将它们再次包含在项目中。 2.将jrxml文件包含到项目中并使用Compile Manager编译它。 3.我阅读了一些教程和问题，说明将表达式放在主报告中的子报表元素

$ P {SUBREPORT_DIR} +＆＃34; subreport_2.jasper＆＃34;

但我仍然继续得到同样的错误，我不知道我做错了什么以下是我的代码

用于查看报告的应用程序中的方法

@FXML
    public void btnMarkingSchemeClicked(ActionEvent actionEvent) {
        try {

//            JasperReport compiledReport = (JasperReport) JRLoader.loadObject(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/MarkingScheme.jasper"));
            JasperReport compiledReport = JasperCompileManager.compileReport(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/MarkingScheme.jrxml"));
            HashMap<String, Object> parameters = new HashMap<>();
            parameters.put("assignID", aid);
            parameters.put("course", cmbCourse.getSelectionModel().getSelectedItem().toString());
            parameters.put("subject", cmbSub.getSelectionModel().getSelectedItem().toString());
            parameters.put("semester", cmbSem.getSelectionModel().getSelectedItem().toString());
            parameters.put("assign", ctrlAssign.search(aid).getAssignName());
//            JasperReport subReport = (JasperReport) JRLoader.loadObject(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/Answers.jasper"));
            JasperReport subReport = JasperCompileManager.compileReport(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/Answers.jrxml"));
            parameters.put("subReport", subReport);
            JasperPrint fillReport = JasperFillManager.fillReport(compiledReport, parameters, ConnectionFactory.getInstance().getConnection());
            JasperViewer.viewReport(fillReport, false);

        } catch (JRException | SQLException | ClassNotFoundException ex) {
            Logger.getLogger(ViewAssignmentsController.class.getName()).log(Level.SEVERE, null, ex);
        }

    }

Answer 1

您的 subreportExpression 标签应该是 $P{SUBREPORT_DIR} + "Answer.jasper"，如下所示：

<subreportExpression><![CDATA[$P{SUBREPORT_DIR} + "Answer.jasper"]]></subreportExpression>

并且您需要根据您的上下文为 $P{SUBREPORT_DIR}

动态提供路径

我在 Grails 上使用 Groovy！基本上，报告遗漏了 jrxml 中 SUBREPORT_DIR 的参数值。我的报告和子报告位于 web-app/reports 文件夹中。因此，在使用 subReport 生成报告时，我添加了如下所示的路径值：

params.put('SUBREPORT_DIR', getReportDirectory() + File.separator)

其中 getReportDirectory() 函数如下所示：

def getReportDirectory() {
        String REPORT_DIRECTORY = null;
        if (!REPORT_DIRECTORY) {
            File reportFolder = ApplicationHolder.application.parentContext.getResource('/reports').file;
            REPORT_DIRECTORY = reportFolder.absolutePath;
        }

       return REPORT_DIRECTORY;
}

Answer 2

这是因为即使您创建了一个名为＆＃34; subReport＆＃34;的参数。它没有在任何地方使用过。

           <subreport>
            <reportElement x="100" y="20" width="440" height="20" uuid="72f8c7c2-82ca-48d3-bb89-d5bb4846e1bc"/>
            <subreportParameter name="qid">
                <subreportParameterExpression><![CDATA[$F{qid}]]></subreportParameterExpression>
            </subreportParameter>
            <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
            <subreportExpression><![CDATA["Answers.jasper"]]></subreportExpression>
        </subreport>

请参阅？它仍然是＆＃34; Answers.jasper ＆＃34;在主要报告中。这就是为什么它在Jasper Studio中运行良好的原因。让我们把它改成，

           <subreport>
            <reportElement x="100" y="20" width="440" height="20" uuid="72f8c7c2-82ca-48d3-bb89-d5bb4846e1bc"/>
            <subreportParameter name="qid">
                <subreportParameterExpression><![CDATA[$F{qid}]]></subreportParameterExpression>
            </subreportParameter>
            <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
            <subreportExpression><![CDATA[$P{subReport}]]></subreportExpression>
        </subreport>
