Java 程序在 build 上运行但不在 fat jar 中

Question

我有一个使用 Jasper Reports API 生成 PDF 的 Java 应用程序。它构建良好，但我必须通过 Netbeans/iReport 插件添加一些字体，以便它们在导出 PDF 时显示。在清理和构建时它很好，一切正常。

但是当我构建一个 fat jar(通过 build.xml 中的一些 package-for-store 行)时，报告不会运行。通过终端运行时，我收到此错误(对不起，文字墙):

当我添加字体时，我将它们添加到一个 jar 中，然后将其添加到类路径中。通过“未找到输入流”错误，我猜这与这些字体有关。但是在正常的清理和构建过程中一切正常，但我不明白为什么 fat jar 不起作用。

有什么想法吗？

Answer 1

我被同样的问题困扰了两天，找不到任何可以帮助我的东西。我希望这可以帮助任何面临同样问题的人。

这是我解决问题的方法。

首先是我正在使用的工具

• 用于创建我的报告的 Jaspersoft Studio 6.0.3
• Jasperreport 库 6.0.3
• Arial Unicode MS，嵌入字体
• Netbeans 8.0.2

因此，首先我修改了 jasperreports-6.0.3.jar 中的文件 jasperreports_extension.properties 并包含了以下几行

net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.dejavu=net/sf/jasperreports/fonts/fonts.xml

由于某种原因，当我构建我的 jar 文件时，jasperreports-6.0.3.jar 中的 jasperreports_extension.properties 文件与 jasperreports-fonts-6.0.3 中的文件之间存在冲突。 jar 和最后一个将被覆盖。

现在为了包含我的字体 (Arial Unicode MS)，我编辑了文件 /net/sf/jasperreports/fonts/fonts.xml 并插入了以下代码:

<fontFamily name="Arial Unicode MS">
    <normal>net/sf/jasperreports/fonts/ArialUnicodeMS/ARIALUNI.TTF</normal>
    <pdfEncoding>Identity-H</pdfEncoding>
    <pdfEmbedded>true</pdfEmbedded>
    <exportFonts>
    </exportFonts>
</fontFamily>

在此之后，我将我的字体包含在 jasperreports-fonts-6.0.3.jar 中。

现在这非常重要，当您创建 jar 文件时，请确保在提取 jasperreports-6.0.3.jar 之前提取 jasperreports-fonts-6.0.3.jar。

这是我的build.xml
