Apache poi：在 docx 文本框中旋转文本

Question

客户要求能够将可编辑注释添加到由网络应用程序自动生成的 docx 文档中。我通过向文档添加一些可编辑的文本框来实现该要求。现在客户希望其中一些注释有垂直文本，但我找不到任何关于如何实现此功能的示例。我应该旋转文本框还是包含的文本？我应该使用哪个 class ？你能提供任何 link 的例子吗，我到目前为止已经找到 none 了？下面是我用来添加文本框的代码：

try {
                    CTGroup ctGroup = CTGroup.Factory.newInstance();

                    CTRect ctRect = ctGroup.addNewRect();
                    ctRect.setStyle(
                              String.format(
                                      "position:absolute;width: %scm;"   
                                    + "height:%scm;" 
                                    + "top:%scm;"
                                    + "left:%scm;"
                                    + "mso-position-horizontal-relative:page;"
                                    + "mso-position-vertical-relative:page;",
                                    nota.getWordPosition().getWidth()/10,//mm->cm
                                    nota.getWordPosition().getHeight()/10,//mm->cm
                                    nota.getWordPosition().getY(),
                                    nota.getWordPosition().getX()
                            )
                      );
                      CTTxbxContent ctTxbxContent = ctRect.addNewTextbox().addNewTxbxContent();
                      String[] noteLines = nota.getDescription().split("\n|\r\n");
                      CTP noteCTP = ctTxbxContent.addNewP();
                      for(String line : noteLines){
                         CTR noteCTR = noteCTP.addNewR();
                         noteCTR.addNewT().setStringValue(line);
                         noteCTR.addNewCr();
                      }
                      
                      Node ctGroupNode = ctGroup.getDomNode(); 
                      CTPicture ctPicture = CTPicture.Factory.parse(ctGroupNode);
                      
                      XWPFRun noteRun = imageParagraph.createRun(); 
                      
                      CTR cTR = noteRun.getCTR();
                      cTR.addNewPict();
                      cTR.setPictArray(0, ctPicture);
                     
                      
                } catch (Exception e) {
                    logger.warn("failed to add a note " +  e.getMessage(),e);
                    throw new ReportGeneratorException("error adding note on pages " + nota.getPages() + "(id " + nota.getId() +")");
                }

那将是 CTTextbox 的风格。在那里你可以设置“layout-flow:vertical;mso-layout-flow-alt:bottom-to-top”。这意味着垂直文本从下到上流动。

...
CTTextbox ctTextbox = ctRect.addNewTextbox();
ctTextbox.setStyle("layout-flow:vertical;mso-layout-flow-alt:bottom-to-top");
...

如何获得？创建默认文本框。使用 Word GUI 打开文件。根据需要在那里设置文本方向。保存文件。解压缩 *.docx 并查看 /word/document.xml。在那里你会发现：

<w:pict>
 <v:rect style="position:absolute;...">
  <v:textbox style="...;layout-flow:vertical;mso-layout-flow-alt:bottom-to-top;...">
   <w:txbxContent>
    ...
   </w:txbxContent>
  </v:textbox>
 </v:rect>
</w:pict>

  FileOutputStream out = new FileOutputStream("WordTextBox.docx");
  doc.write(out);
  out.close();
  doc.close();
