Pentaho/POI 抛出 InspirationTargetException

Question

我正在尝试将我的所有 java 应用程序升级到 openJDK11（来自 Oracle 8）。我注意到使用 Pentaho 的报告服务器中存在一个问题。

看来Excel自动调整大小功能需要openJDK11中的libfontconfig.so，

但是我可以在 /usr/lib64/libfontconfig.so 找到该模块。

有办法解决这个问题吗？

更新 ：

添加“-Dsun.java2d.debugfonts=true”后，我得到了以下日志：

Answer 1

通过做两件事解决（使用 docker 实现）：

1. 添加配置变量：

   这是为了让 JDK 知道 libfontconfig.so 的位置

ENV LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/lib/:/usr/lib64/"

2. 将默认文件添加到 JDK/lib 文件夹：

   这是必需的，因为 openjdk 默认没有它。以下文件来自Oracle JDK8

ADD ./src/main/resources/fontconfig.bfc /opt/jdk11/jdk-11.0.1/lib/fontconfig.bfc

ADD ./src/main/resources/fontconfig.properties.src /opt/jdk11/jdk-11.0.1/lib/fontconfig.properties.src

ADD ./src/main/resources/fonts /opt/jdk11/jdk-11.0.1/lib/fonts

更新：上述解决方案有效，但有时在加载redhat linux后，似乎无法找到字体并给出"java.lang.ClassCastException: class sun.font.CompositeFont cannot be cast to class sun.font.PhysicalFont (sun.font.CompositeFont and sun.font.PhysicalFont are in module java.desktop of loader 'bootstrap')". 10-30 分钟后，问题消失。

解决方案：

1. 添加额外的 TTF 文件（对我来说是 calibri.ttf ）并复制到 /usr/share/fonts/TTF

2. 执行此命令： fc-cache -fv 这可以确保字体配置立即加载字体。

ADD ./src/main/resources/fonts/*.ttf /usr/share/fonts/TTF/
RUN fc-cache -fv
