Apache poi Java:如何更改WORD文档中列表编号的字体名称和大小

Question

我写了一个方法来为word文档的某些段落添加编号，但我似乎无法自定义列表编号的字体名称和字体大小(例如：a.我的项目1，b.我的项目2(。我可以自定义段落中的字体，但无法自定义列表编号的字体名称和字体大小。下面的代码中有我可能缺少的东西吗？

public static BigInteger listNumbering(XWPFDocument doc, BigInteger abstractNumID) {
CTAbstractNum cTAbstractNum = CTAbstractNum.Factory.newInstance();
cTAbstractNum.setAbstractNumId(abstractNumID);
CTLvl cTLvl = cTAbstractNum.addNewLvl();
cTLvl.addNewNumFmt().setVal(STNumberFormat.DECIMAL);
cTLvl.addNewLvlText().setVal("%1.");
cTLvl.addNewStart().setVal(BigInteger.valueOf(1));
XWPFAbstractNum abstractNum = new XWPFAbstractNum(cTAbstractNum);
XWPFNumbering numbering = doc.createNumbering();
abstractNumID = numbering.addAbstractNum(abstractNum);
BigInteger numID = numbering.addNum(abstractNumID);
return numID;
}

Answer 1

您的代码只为文档创建一个十进制编号格式，并获得适当的NumID。NumID需要应用于文件中应编号的段落。格式由段落决定。

编号本身的格式由段落的运行属性决定。遗憾的是，到目前为止，XWPFParagraph中还没有设置段落运行属性的方法。所以我们需要使用低级别的ooxml-schemas类来实现这一点。在下面的代码中，方法setParagraphRunProperties(XWPFParagraph paragraph, String fontFamily, int fontSize)就是这样做的。

编号段落的格式由其文本运行的格式决定。
