在redhat服务器上使用java.awt.HeadlessException时,我得到了Docx4jReplacedElementFactory。有人知道解决办法吗?(除了运行xvfb)
我已经深入研究了堆栈跟踪,问题的根源是java.awt.GraphicsEnvironment.getDefaultScreenDevice(),它在无头环境中运行时抛出异常。如文档所述:“throws:headlessexception-if isheadless()返回true”(请参阅java.awt.HeadlessException thrown from HeadlessGraphicsEnvironment.getDefaultScreenDevice上的注释)。
如果getDefaultScreenDevice按指定方式工作,那么在使用docx4j时是否有其他方法可以避免这样做?
org.docx4j.org.xhtmlrenderer.util.ImageUtil.getGraphicsConfiguration的来源来看,我们看到:

private static GraphicsConfiguration getGraphicsConfiguration() {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
  -> GraphicsDevice gs = ge.getDefaultScreenDevice();
    GraphicsConfiguration gc = gs.getDefaultConfiguration();
    return gc;
}
