设置目录字体 和字号

Answer 1

【以下回答由 GPT 生成】

问题所在： 目录的字体和字号没有正确设置。

解决方案： 要设置目录的字体和字号，你需要创建一个新的样式，并在样式中设置字体和字号，然后将该样式应用到段落上。

以下是修改后的代码示例：

@Test
public void main2() throws Exception {
    XWPFDocument document = new XWPFDocument();

    // 创建段落
    XWPFStyles newStyles = document.createStyles();
    String heading1 = "Heading1";
    createHeadingStyle(document, newStyles, heading1, 1, 45, "000000", "宋体");

    heading1 = "Heading2";
    createHeadingStyle(document, newStyles, heading1, 2, 30, "000000", "宋体");

    // 创建目录段落
    XWPFParagraph mulu = document.createParagraph();
    mulu.setStyle("Heading3");

    // 设置目录字体和字号
    XWPFRun run0 = mulu.createRun();
    run0.setText("目   录");
    run0.setFontSize(22);
    run0.setFontFamily("黑体");
    mulu.setAlignment(ParagraphAlignment.CENTER);
    mulu.setSpacingAfter(600);

    // 创建正文段落
    XWPFParagraph firstParagraph = document.createParagraph();
    firstParagraph.setStyle("Heading1");
    CTSimpleField ctSimpleField = firstParagraph.getCTP().addNewFldSimple();
    ctSimpleField.setInstr("TOC \\o \"1-4\" \\h \\z \\u");

    firstParagraph = document.createParagraph();
    firstParagraph.setStyle("Heading2");
    XWPFRun run1 = firstParagraph.createRun();
    run1.setText("标题1");
    run1.setFontSize(21);
}

private static void createHeadingStyle(XWPFDocument document, XWPFStyles styles, String headingStyleId, int headingLevel, int headingSize, String headingColor, String headingFontFamily) {
    CTStyle ctStyle = CTStyle.Factory.newInstance();
    ctStyle.setStyleId(headingStyleId);
    CTString styleName = CTString.Factory.newInstance();
    styleName.setVal(headingStyleId);
    ctStyle.setName(styleName);
    CTDecimalNumber indentNumber = CTDecimalNumber.Factory.newInstance();
    indentNumber.setVal(BigInteger.valueOf(headingLevel));

    // 设置字体和字号
    CTRPr ctRPr = CTRPr.Factory.newInstance();
    CTFonts ctFonts = ctRPr.isSetRFonts() ? ctRPr.getRFonts() : ctRPr.addNewRFonts();
    ctFonts.setAscii(headingFontFamily);
    ctFonts.setEastAsia(headingFontFamily);
    ctFonts.setHAnsi(headingFontFamily);
    ctRPr.setSz(BigInteger.valueOf(headingSize * 2));
    ctRPr.setSzCs(BigInteger.valueOf(headingSize * 2));

    // 设置字体颜色
    CTColor ctColor = CTColor.Factory.newInstance();
    ctColor.setVal(headingColor);
    ctRPr.setColor(ctColor);

    // 设置段落缩进
    CTPPr ctPPr = CTPPr.Factory.newInstance();
    CTInd ctInd = ctPPr.isSetInd() ? ctPPr.getInd() : ctPPr.addNewInd();
    ctInd.setLeft(BigInteger.valueOf(headingLevel * 720));
    ctStyle.setPPr(ctPPr);

    ctStyle.setRPr(ctRPr);
    ctStyle.setBasedOn(XWPFStyles.DEFAULT_HEADING_STYLE);

    // 将样式添加到文档
    XWPFStyle style = new XWPFStyle(ctStyle);
    styles.addStyle(style);
}

注意： - 通过CTRPr设置字体和字号时，要注意使用的单位是半个点，所以需要使用字号乘以2。 - 通过CTInd设置段落缩进时，单位是20分之1点，所以段落缩进的值为headingLevel * 720时，表示缩进headingLevel个字符的宽度。
