Pentaho/POI 抛出 InvocationTargetException

Pentaho/POI 抛出 InvocationTargetException

pentahojava-11fontconfig

7

我正试图将我所有的Java应用程序升级到OpenJDK11（从Oracle 8），然而我注意到我的报告服务器使用Pentaho时遇到了一个问题。

似乎Excel自动调整大小功能需要在OpenJDK11中使用libfontconfig.so模块，

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

有什么解决方法吗？

更新：

在添加“-Dsun.java2d.debugfonts=true”后，我获得了以下日志：

通过两个步骤解决问题（使用Docker实现）:

添加配置变量：

这是让JDK知道libfontconfig.so位置的必要步骤。

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

将默认文件添加到JDK / lib文件夹中：

这是必要的，因为openjdk默认没有这些文件。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：以上解决方案有效，但有时在加载redhat linux后，似乎无法找到字体并出现错误

"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。

解决方法：

添加额外的TTF文件（对我而言是Calibri.ttf），并将其复制到/usr/share/fonts/TTF。
执行此命令：fc-cache -fv，以确保字体被fontconfig立即加载。

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