Java 使用POI操作Word的页眉和页脚的方法及示例代码

本文主要介绍Java中，使用POI操作Word文档的页眉和页脚的格式和样式的方法，以及相关的示例代码。

1、安装引用Apache POI

下载地址：https://poi.apache.org/download.html

Maven中pom.xml中添加依赖如下：

    org.apache.poi    poi-ooxml    3.14    org.apache.poi    poi-excelant    3.14    org.apache.poi    poi-examples    3.14    org.apache.xmlbeans    xmlbeans    2.6.0

2､需要import导入的包

import com.auth0.jwt.internal.org.apache.commons.lang3.StringUtils;
import org.apache.poi.util.Units;
import org.apache.poi.xwpf.model.XWPFHeaderFooterPolicy;
import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

import java.io.*;
import java.math.BigInteger;
import java.util.*;

3､添加不带图片的页眉

  public void createHeader(XWPFDocument doc, String orgFullName) throws Exception {
        /*
         * 对页眉段落作处理
         * */
        CTSectPr sectPr = doc.getDocument().getBody().addNewSectPr();
        XWPFHeaderFooterPolicy headerFooterPolicy = new XWPFHeaderFooterPolicy(doc,sectPr);
        XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);
        XWPFParagraph paragraph = header.getParagraphArray(0);
        paragraph.setBorderBottom(Borders.THICK);

        /*
         * 添加字体页眉，公司全称
         * */
        if (StringUtils.isNotEmpty(orgFullName)) {
            XWPFRun run = paragraph.createRun();
            run.setText(orgFullName);
            //setXWPFRunStyle(run,"新宋体",10);
        }
    }

4､创建带图片页眉

  /**     * 对页眉处理  页眉包含公司名称   二维码图片     * @param doc     * @param orgFullName   公司全称     * @param logoFilePath   图片的地址     * @throws Exception     */    public void createHeader(XWPFDocument doc, String orgFullName, String logoFilePath) throws Exception {        /*         * 对页眉段落作处理，使图片在页眉右边，公司全称在页眉左边         * */        CTSectPr sectPr = doc.getDocument().getBody().addNewSectPr();        XWPFHeaderFooterPolicy headerFooterPolicy = new XWPFHeaderFooterPolicy(doc,    sectPr);        XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);        XWPFParagraph paragraph = header.getParagraphArray(0);        paragraph.setAlignment(ParagraphAlignment.BOTH);   //设置段落左对齐        paragraph.setBorderBottom(Borders.THICK);    //设置下划线        XWPFRun run = paragraph.createRun();        setXWPFRunStyle(run,"新宋体",10);        /*         * 添加字体页眉，公司全称         * 公司全称在右边         * */        if (StringUtils.isNotEmpty(orgFullName)) {            run = paragraph.createRun();            run.setText(orgFullName);            setXWPFRunStyle(run,"新宋体",10);        }        //处理两个段落之间的制表符宽度        run.addTab();        CTTabStop tabStop = paragraph.getCTP().getPPr().addNewTabs().addNewTab();        tabStop.setVal(STTabJc.CENTER);        int twipsPerInch =  1450;        tabStop.setPos(BigInteger.valueOf(6 * twipsPerInch));        /*         * 取到图片的字节流         * */        if (StringUtils.isNotEmpty(logoFilePath)) {            File file=new File(logoFilePath);            InputStream is = new FileInputStream(file);            XWPFPicture picture = run.addPicture(is, XWPFDocument.PICTURE_TYPE_JPEG, logoFilePath, Units.toEMU(40), Units.toEMU(40));            String blipID = "";            for(XWPFPictureData picturedata : header.getAllPackagePictures()) {    //这段必须有，不然打开的logo图片不显示                blipID = header.getRelationId(picturedata);            }            picture.getCTPicture().getBlipFill().getBlip().setEmbed(blipID);            run.addTab();            is.close();        }    }

5､设置页脚的样式

/**     * 设置页脚的字体样式     *     * @param r1 段落元素     */    private void setXWPFRunStyle(XWPFRun r1,String font,int fontSize) {        r1.setFontSize(fontSize);        CTRPr rpr = r1.getCTR().isSetRPr() ? r1.getCTR().getRPr() : r1.getCTR().addNewRPr();        CTFonts fonts = rpr.isSetRFonts() ? rpr.getRFonts() : rpr.addNewRFonts();        fonts.setAscii(font);        fonts.setEastAsia(font);        fonts.setHAnsi(font);    }

6､设置页眉和页脚样式

//获取word文档解析对象XWPFDocument document = new XWPFDocument(POIXMLDocument.openPackage(sourceUrl));//设置文本中表格内容样式//---------------------------------------------------------List < XWPFTable > tbls = document.getTables();for (int i = 0; i < tbls.size(); i++) {    String tbl = tbls.get(i).getText();    tbls.get(i).setStyleID("tbl-text"); //前提是styles.xml 中有styleId为tbl-text}//---------------------------------------------------------//设置页眉页脚样式//---------------------------------------------------------List < XWPFHeader > pageHeaders = document.getHeaderList();for (int i = 0; i < pageHeaders.size(); i++) {    List < XWPFParagraph > headerPara = pageHeaders.get(i).getParagraphs();    for (int j = 0; j < headerPara.size(); j++) {        headerPara.get(j).setStyle("page-header"); //前提是styles.xml 中有styleId为 page-header    }}List < XWPFFooter > pageFooters = document.getFooterList();for (int i = 0; i < pageFooters.size(); i++) {    List < XWPFParagraph > footerPara = pageFooters.get(i).getParagraphs();    for (int j = 0; j < footerPara.size(); j++) {        footerPara.get(j).setStyle("page-footer"); //前提是styles.xml 中有styleId为 page-footer    }}
