Java Apache POI Word文件分节设置页眉和页脚

1、引用Apache POI

使用Apache POI操作Word文件，需要在项目中包含了Apache POI的依赖。如使用Maven，可以在pom.xml文件中添加以下依赖，如下，

<dependencies>
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
        <version>4.1.2</version>
    </dependency>
</dependencies>

2、将Word文档分节

要在Java中使用Apache POI库将Word文档分节，可以通过在文档中插入分节符来实现。代码如下，

try (XWPFDocument document = new XWPFDocument()) {
    // 添加第一节内容
    XWPFParagraph paragraph1 = document.createParagraph();
    paragraph1.setAlignment(ParagraphAlignment.CENTER);
    XWPFRun run1 = paragraph1.createRun();
    run1.setText("第一节内容");
     
   
    //分节
    CTBody body = document.getDocument().getBody();
    CTSectPr sectPr = body.getSectPr();
    if (sectPr != null) {
        XWPFParagraph lastParagraph = document.createParagraph();
        lastParagraph.getCTP().addNewPPr().setSectPr(sectPr);
        body.unsetSectPr();
    }
    document.createParagraph().setPageBreak(true);
     
    // 添加第二节内容
    XWPFParagraph paragraph2 = document.createParagraph();
    paragraph2.setAlignment(ParagraphAlignment.CENTER);
    XWPFRun run2 = paragraph2.createRun();
    run2.setText("第二节内容");
    // 创建新文档
    //XWPFDocument document = new XWPFDocument();
     
    // 保存文档
    try (FileOutputStream out = new FileOutputStream("cjavapy.docx")) {
        document.write(out);
    }
} catch (IOException e) {
    e.printStackTrace();
}

3、将Word文档设置页眉和页脚

可以使用Java POI库在Word文档中设置页眉和页脚样式，代码如下，

try (XWPFDocument document = new XWPFDocument()) {
      
      // 创建一个段落
      XWPFParagraph paragraph = document.createParagraph();
      XWPFRun run = paragraph.createRun();
      run.setText("www.cjavapy.com with header and footer.");

      // 设置页眉
      XWPFHeaderFooterPolicy headerFooterPolicy = document.createHeaderFooterPolicy();

      // 创建页眉内容
      XWPFHeader header = headerFooterPolicy.createHeader(XWPFHeaderFooterPolicy.DEFAULT);
      XWPFParagraph headerParagraph = header.createParagraph();
      headerParagraph.setAlignment(ParagraphAlignment.CENTER);
      XWPFRun headerRun = headerParagraph.createRun();
      headerRun.setText("www.cjavapy.com header text");

      // 设置页脚
      XWPFFooter footer = headerFooterPolicy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);
      XWPFParagraph footerParagraph = footer.createParagraph();
      footerParagraph.setAlignment(ParagraphAlignment.CENTER);
      XWPFRun footerRun = footerParagraph.createRun();
      footerRun.setText("www.cjavapy.com footer text");

      // 保存文档
      try (FileOutputStream out = new FileOutputStream("cjavapy.docx")) {
          document.write(out);
      }
} catch (IOException e) {
    e.printStackTrace();
}

4、将Word文档分节设置页眉

使用Apache POI库可以编程方式操作Microsoft Word文档。要给Word文档的设置页眉，代码如下，

try (XWPFDocument document = new XWPFDocument()) {
       
    // 第一节内容
    XWPFParagraph para1 = document.createParagraph();
    XWPFRun run1 = para1.createRun();
    run1.setText("www.cjavapy.com 第一节内容");
    para1.setPageBreak(true); // 分页符
       
    // 创建第一节的页眉
    CTSectPr sectPr1 = document.getDocument().getBody().addNewSectPr();
    XWPFHeaderFooterPolicy headerFooterPolicy1 = new XWPFHeaderFooterPolicy(document, sectPr1);
    XWPFHeader header1 = headerFooterPolicy1.createHeader(XWPFHeaderFooterPolicy.DEFAULT);
    XWPFParagraph headerPara1 = header1.createParagraph();
    headerPara1.setAlignment(ParagraphAlignment.CENTER);
    XWPFRun headerRun1 = headerPara1.createRun();
    headerRun1.setText("cjavapy 页眉 1");
       
    //分节
    CTBody body = document.getDocument().getBody();
    CTSectPr sectPr = body.getSectPr();
    if (sectPr != null) {
        XWPFParagraph lastParagraph = document.createParagraph();
        lastParagraph.getCTP().addNewPPr().setSectPr(sectPr);
        body.unsetSectPr();
    }
    document.createParagraph().setPageBreak(true);
       
    // 第二节内容
    XWPFParagraph para2 = document.createParagraph();
    XWPFRun run2 = para2.createRun();
    run2.setText("www.cjavapy.com 第二节内容");
       
    // 创建第二节的页眉
    CTSectPr sectPr2 = document.getDocument().getBody().addNewSectPr();
    XWPFHeaderFooterPolicy headerFooterPolicy2 = new XWPFHeaderFooterPolicy(document, sectPr2);
    XWPFHeader header2 = headerFooterPolicy2.createHeader(XWPFHeaderFooterPolicy.DEFAULT);
    XWPFParagraph headerPara2 = header2.createParagraph();
    headerPara2.setAlignment(ParagraphAlignment.CENTER);
    XWPFRun headerRun2 = headerPara2.createRun();
    headerRun2.setText("cjavapy 页眉 2");
    // 保存文档
    try (FileOutputStream out = new FileOutputStream("cjavapy.docx")) {
        document.write(out);
    }
} catch (IOException e) {
    e.printStackTrace();
}
