Java 使用POI操作Word的页眉和页脚的方法及示例代码

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：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.14</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-excelant</artifactId>
    <version>3.14</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-examples</artifactId>
    <version>3.14</version>
</dependency>
<dependency>
    <groupId>org.apache.xmlbeans</groupId>
    <artifactId>xmlbeans</artifactId>
    <version>2.6.0</version>
</dependency>

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
    }
}
