如何更改 apache poi word 文档中的文本方向(不是段落对齐)?(XWPF)

问题描述：

我正在尝试使用 Apache poi word 3.8 以波斯语/阿拉伯语创建 word 文档.我的问题是:如何更改文档中的文本方向?(这意味着改变文本方向，而不仅仅是改变段落文本对齐方式)在 MS Word 中，我们可以使用从右到左的文本方向来更改文本方向并右对齐设置对齐方式.什么相当于 poi set 属性中的第一个?

I'm trying to use Apache poi word 3.8 to create word document in persian/arabic language. My question is: how change text direction in document? ( it means changing text direction not changing just paragraph text alignment) In MS Word we could use Right-to-left text direction to change text direction and Align Right to set alignment. What’s equivalent of the first one in poi set property?

答

这是双向文本方向支持 (bidi)，默认情况下尚未在 apache poi 中实现.但是底层对象 org.openxmlformats.schemas.wordprocessingml.x2006.main.CTPPrBase 支持这一点.所以我们必须从 XWPFParagraph 中获取这个底层对象.

This is bidirectional text direction support (bidi) and is not yet implemented in apache poi per default. But the underlying object org.openxmlformats.schemas.wordprocessingml.x2006.main.CTPPrBase supports this. So we must get this underlying object from the XWPFParagraph.

示例:

import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.*;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTPPr;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STOnOff;

public class CreateWordRTLParagraph {

 public static void main(String[] args) throws Exception {

  XWPFDocument doc= new XWPFDocument();

  XWPFParagraph paragraph = doc.createParagraph();
  XWPFRun run = paragraph.createRun();
  run.setText("Paragraph 1 LTR");

  paragraph = doc.createParagraph();

  CTP ctp = paragraph.getCTP();
  CTPPr ctppr;
  if ((ctppr = ctp.getPPr()) == null) ctppr = ctp.addNewPPr();
  ctppr.addNewBidi().setVal(STOnOff.ON);

  run = paragraph.createRun();
  run.setText("السلام عليكم");

  paragraph = doc.createParagraph();
  run = paragraph.createRun();
  run.setText("Paragraph 3 LTR");
    
  FileOutputStream out = new FileOutputStream("WordDocument.docx");
  doc.write(out);
  out.close();
  doc.close();    
 }
}
