Apache Poi - XWPF：如何更改 docx 中页脚页码的字体颜色、大小和样式

Question

我试过下面的代码，但似乎 setColor() 只更新了段落中的文本 -- 它不影响 CTSimpleField 页码的颜色。

CTSectPr sectPr = getSectionProperty(0);
CTHdrFtrRef footerRef = sectPr.addNewFooterReference();
XWPFFooter footer = headerFooterPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);
footerRef.setId(footer.getPackageRelationship().getId());

XWPFParagraph paragraph = footer.createParagraph();

CTSimpleField simpleField =  paragraph.getCTP().addNewFldSimple().setInstr("PAGE  \* Arabic  \* MERGEFORMAT");

XWPFRun run = paragraph.createRun();
run.setText("Page ");
run.setColor("ffffff");

有没有办法更新 CTSimpleField 字体颜色、样式和大小？或者是否有不同的方法来生成页码，我们可以更新它们的字体颜色？

Answer 1

setColor是XWPFRun的一个方法。所以它只影响 XWPFRun.

中的文本

方法XWPFParagraph paragraph ...; ... paragraph.getCTP().addNewFldSimple() 是向Office Open XML Word 文档添加字段的最简单方法。但是，由于这会在所有文本运行之外的段落中添加一个字段，因此无法进行文本格式化。这是因为 Word 中的文本格式只能用于文本运行s.

如果需要特殊的文本格式，则字段必须在文本中运行。但是在文本运行中不可能有简单字段。要在文本运行中存储字段，必须有一个字段字符类型为 BEGIN 的特殊文本运行，后跟字段内容为 in-string 文本的特殊文本运行，后跟一个特殊文本运行，其字段字符类型为 END.

以下代码显示了这一点。所有使用的 XWPFRun 都提供来自 atting 的文本。
