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：

<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
}

}
