【问题描述】：

我有打印到 pdf 的 javafx 应用程序。我在 linux (UBUNTU 20.04) 上工作正常

但是当我在 WIndow 上运行它时，我得到了

我已经包含了 jaspter 报告 maven dendencies

     <dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>6.17.0</version>
    </dependency>
    <dependency>
        <groupId>net.sf.jasperreports</groupId>
        <artifactId>jasperreports-fonts</artifactId>
        <version>6.11.0</version>
    </dependency>

这行代码执行的时候报错

JasperReport jasperReportInstance = session.getJasperReportInstance();

JasperPrint print = JasperFillManager.fillReport(jasperReportInstance, 参数, new JREmptyDataSource());

当我调用填充报告时，我在窗口上收到错误消息

我正在使用 java 17 oracle jdk jafax 17.0.1。

有什么想法吗？

【问题讨论】：

minimal reproducible example 请包括完整的堆栈跟踪 .. 与 javafx 的关系在哪里？
如果你格式化跟踪和代码as code而不是引用，它更容易阅读。
添加了全栈跟踪@kleopatra
你需要“recompile from source JRXMLs”。尝试创建一个没有 JavaFX 的小型纯 Java 应用程序，看看是否可以创建报告。
我发现了问题。在 Linux 中这工作 JasperReport jasperReport = (JasperReport) JRLoader.loadObject(getClass().getResourceAsStream("/com/sable/inv.jasper"));在 Windo 中，路径不起作用。我该如何解决这两个平台的问题？

【解决方案1】：

我解决了这个问题。问题是我的 jasper 报告使用的是加载报告时未找到的自定义字体。如果您包含了 jasperreports-fonts，我尝试使用内置 jasper 报告字体。转到 jar 并找到 fonts.xml 将您使用的字体名称替换为默认字体名称。编译.jrxml并运行jasper报告

类路径中的 URL 没有问题。如果你的报告在哪里

src/main/resource/reports/customer.jaspper

然后打印我使用的报告

 JasperPrint print = JasperFillManager.fillReport(ClassLoader.getSystemResourceAsStream("reports/customer.jasper"), parameters, new JREmptyDataSource());

从 jar 运行时，该解决方案也很有效

我希望能帮助别人。
