无法找到Jasper Report（.jrxml）源路径

Question

我有6个Jasper Reports，正在等待这个代码编译每个，而fillReport使用我传入的参数。我正在使用Eclipse并使用Jaspersoft Studio创建报告。

public class PrintCertificate { 
private static Connection con = null;

public PrintCertificate( String certType, String firstName, String lastName, String confirmDate, String managerName) {
    DbWorker db = new DbWorker();

    try {
        con = DriverManager.getConnection("jdbc:mysql://localhost:3306/db", "root", "password");
    } catch (Exception e) {
        new DbConnectErrorDialog().setVisible(true);
    }
    String OUT_PUT = "C:/tmp/" + firstName.toLowerCase() + "_" + lastName.toLowerCase() + "_" + certType + ".docx";
    String REPORT = "";

    if(certType.equals("rci_eng")) {
        REPORT = "./certificates/RCI_Eng.jrxml";
    } else if(certType.equals("rci_span")) {
        REPORT = "./certificates/RCIA_Span.jrxml";
    } else if(certType.equals("confirm_eng")) {
        REPORT = "./certificates/Confirm_Eng.jrxml";
    } else if(certType.equals("confirm_span"))  {
        REPORT = "./certificates/Confirm_Span.jrxml";
    } else if(certType.equals("comm_eng")) {
        REPORT = "./certificates/Comm_Eng.jrxml";
    } else if(certType.equals("comm_span")) {
        REPORT = "./certificates/Comm_Span.jrxml";
    }

        HashMap<String, Object> map = new HashMap<>();
        map.put("FirstName",firstName);
        map.put("LastName",lastName);
        map.put("ManagerName", managerName);
        map.put("DateOfConfirmation", confirmDate);

        try  {
            JasperReport jr = JasperCompileManager.compileReport(ClassLoader.getSystemResourceAsStream(REPORT));
            JasperPrint jp = JasperFillManager.fillReport(jr, map, con);
            JRDocxExporter export = new JRDocxExporter();
            export.setExporterInput(new SimpleExporterInput(jp));
            export.setExporterOutput(new SimpleOutputStreamExporterOutput(new File(OUT_PUT)));
            SimpleDocxReportConfiguration config = new SimpleDocxReportConfiguration();
            export.setConfiguration(config);
            export.exportReport();
        } catch (JRException ex) {
        }
}
}

当我到达这一行时，它失败了，并说'＃34; Source Not Found＆＃34;并在EventDispatchThread.pumpOneEventForFilters（int）行失败

JasperReport jr = JasperCompileManager.compileReport(ClassLoader
.getSystemResourceAsStream(REPORT));

这让我相信由于REPORT（jrxml的路径）错误。 PrintCertificate.java，报告位于：

/src/print/PrintCertificate.java

/src/certificates/RCI_Eng.jrxml

设置REPORT时我使用了正确的路径吗？

我的建设路径

Answer 1

您应该在库下面运行典型的Jasper报告。

Answer 2

为什么要放。 in＆＃34; REPORT =＆＃34; ./ certificates / Confirm_Eng.jrxml＆＃34;;＆＃34;路径。没有相对路径。
