java-在Jasper报表中有子报表时找不到JRException资源
作者：互联网
我制作了一个jasper报告,其中包含使用JasperSoft Studio的子报告.当我在工作室中预览时,效果很好.但是,当我将其添加到java fx项目中时,我必须将子报表作为参数发送到主报表,对吗？
当我这样做时,我不断收到错误消息,指出未找到子报表资源.
我不认为有任何拼写错误,因为我在几乎所有包含子报告的报告中都尝试了此操作.
这些是我尝试过的
1.使用jaspersoft Studio再次编译报告,并将其再次包含在项目中.
2.将jrxml文件包含到项目中,并使用编译管理器进行编译.
3.我阅读了一些教程和问题,说要将该表达式放在主报告中的subreport元素上,如下所示：
$P{SUBREPORT_DIR} + “subreport_2.jasper”
但我仍然不断收到相同的错误,我不知道我在做什么错
下面是我的代码
应用程序中用于查看报告的方法
@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);
}
}

解决方法:
这是因为即使您创建了一个名为“ subReport”的参数,该参数仍未在任何地方使用.
<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>
看到？主报告中仍然是“ Answers.jasper”.这就是为什么它在Jasper Studio中可以正常工作的原因.让我们将其更改为
<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>
我很确定我不是教您使用Jasper的人：)
希望它能起作用
