我如何可以使用Apache POI添加嵌入式方程docx文件？ [英] How can I add embedded equations to docx files by using Apache POI?

问题描述

我想通过Apache POI编程创建的docx文件。

I want to create a docx file programatically via Apache POI.

我想在一些线路增加一些数学公式。

I want to add some mathematical equations in some lines.

我怎么能在某种程度上做到这一点，当用户打开该文件的docx它看到方程式等式DOCX格式。

How can I do this in a way that when the user open the docx file it see that equations as docx equation form.

我的意思是，我不想简单地给一个背景颜色到运行，我想，当用户执行双击我的方程M​​S-Word中公式的形式打开它。

I mean I don't want simply give a background colour to that run, I want when the user does double click on my equation MS-Word open it in equation forms.

在此先感谢

推荐答案

这是不是真的复杂的：

import java.io.FileOutputStream;

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

import org.openxmlformats.schemas.officeDocument.x2006.math.CTOMath;
import org.openxmlformats.schemas.officeDocument.x2006.math.CTRad;
import org.openxmlformats.schemas.officeDocument.x2006.math.CTR;
import org.openxmlformats.schemas.officeDocument.x2006.math.STStyle;
/*
To
import org.openxmlformats.schemas.officeDocument.x2006.math.CTOMath;
import org.openxmlformats.schemas.officeDocument.x2006.math.CTRad;
import org.openxmlformats.schemas.officeDocument.x2006.math.CTR;
import org.openxmlformats.schemas.officeDocument.x2006.math.STStyle;
the fully ooxml-schemas-1.3.jar is needed as mentioned in https://poi.apache.org/faq.html#faq-N10025
*/

public class CreateWordFormula {

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

  XWPFDocument doc= new XWPFDocument();

  XWPFParagraph paragraph = doc.createParagraph();
  XWPFRun run=paragraph.createRun();  
  run.setText("The Formula: ");

  CTOMath cTOMath = paragraph.getCTP().addNewOMath();
  CTR cTR = cTOMath.addNewR();
  cTR.addNewRPr().addNewSty().setVal(STStyle.P);
  cTR.addNewT2().setStringValue("a²+b²=c²");

  run=paragraph.createRun();  
  run.setText(" text after the formula");

  paragraph = doc.createParagraph();
  run=paragraph.createRun();  
  run.setText("The Formula: ");

  cTOMath = paragraph.getCTP().addNewOMath();
  CTRad cTRad = cTOMath.addNewRad();
  cTR = cTRad.addNewDeg().addNewR();
  cTR.addNewRPr().addNewSty().setVal(STStyle.P);
  cTR.addNewT2().setStringValue("2");
  cTR = cTRad.addNewE().addNewR();
  cTR.addNewRPr().addNewSty().setVal(STStyle.P);
  cTR.addNewT2().setStringValue("a²+b²");

  run=paragraph.createRun();  
  run.setText(" text after the formula");  

  doc.write(new FileOutputStream("WordFormula.docx"));

 }
}

有关 CTOMath 看<一个href=\"http://grep$c$c.com/file/repo1.maven.org/maven2/org.apache.poi/ooxml-schemas/1.1/org/openxmlformats/schemas/officeDocument/x2006/math/CTOMath.java#CTOMath.addNewRad%28%29\" rel=\"nofollow\">http://grep$c$c.com/file/repo1.maven.org/maven2/org.apache.poi/ooxml-schemas/1.1/org/openxmlformats/schemas/officeDocument/x2006/math/CTOMath.java#CTOMath.addNewRad%28%29.
