在 fat jar 中编译应用程序时生成 jasper 报告的问题
Issue with generating jasper report when the app was compiled in fat jar
我已成功将 jasper 报告添加到我的 java 应用程序，并通过字体扩展添加了字体。当我 运行 我的应用程序在 intelij idea 中时，一切正常，报告使用选定的字体生成。但是，当我将所有内容编译成一个统一的（单个、fat 等）jar 文件，将其部署到 Wildfly 并尝试生成报告时，我收到以下错误：

我在 .war 文件 (WEB-INF\lib) 的 lib 文件夹中看到了我的字体扩展 jar。
我的环境：
jasperreports:6.12.2
Wildfly 19
P.S。
很奇怪，我从日志中收到以下错误：
Error loading font family: net.sf.jasperreports.engine.fonts.InvalidFontException: Error loading font "net/sf/jasperreports/fonts/icons/icons.ttf"
因为 icon.ttf 位于 jasperreports:6.12.2.jar
中的 jasper 默认字体文件夹中
我找到了这个问题的解决方案。我将 docker 容器与 WildFly 一起使用，在 docker 中我有 Linux，它没有为字体配置。我使用了以下命令：
输入：
docker exec -it -u 0 wildfly /bin/bash
其中 wildfly 是容器的名称
对于字体（它是解决方案）
sudo apt-get install fontconfig
我已成功将 jasper 报告添加到我的 java 应用程序，并通过字体扩展添加了字体。当我 运行 我的应用程序在 intelij idea 中时，一切正常，报告使用选定的字体生成。但是，当我将所有内容编译成一个统一的（单个、fat 等）jar 文件，将其部署到 Wildfly 并尝试生成报告时，我收到以下错误：
