前言：在日常的工作当中，避免不了会涉及到一些Word文件方面的操作，这篇博客将使用SpringBoot整合开源Apache来操作Word，分享的都是目前实际当中会经常用到的一些功能代码都实际测试过，只分享干货，大家一键复制使用就可以了。
目录
一、引入pom依赖
二、工具类
1、POIUtil操作Word工具类
2、SealUtil工具类
3、SealCircle实体类
4、SealConfiguration配置类
5、SealFont字体类
三、使用方法
1、替换Word当中的通配符
2、替换Word当中的书签
3、Word转Pdf
4、通过Word书签在段落中插入图片
5、生成公章
6、Word盖章
四、Gitee源码

String filePath = "word通配符替换测试.docx";
String outFilePath = "result.docx";
Map<String,Object> dataMap = new HashMap<>();
dataMap.put("name","张三");
dataMap.put("password","123456");
InputStream is = new FileInputStream(filePath);
XWPFDocument doc = new XWPFDocument(is);
//替换段落里面的变量
replaceInPara(doc, dataMap);
//替换表格里面的变量
replaceInTable(doc, dataMap);
response.setCharacterEncoding("UTF-8");
response.addHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("result.docx", "UTF-8"));
response.setContentType("multipart/form-data");
OutputStream os = new BufferedOutputStream(response.getOutputStream());
doc.write(os);
close(os);
close(is);
return "Word通配符替换成功！";
}准备测试文件：word通配符替换测试.docx
浏览器输入：http://localhost:8080/replaceWordText
2、替换Word当中的书签
controller层代码
@GetMapping("/replaceWordTag")
public String replaceWordTag(HttpServletResponse response) throws IOException {
String filePath = "word书签替换测试.docx";
String outFilePath = "result.docx";
//读文件
InputStream is = new FileInputStream(filePath);
XWPFDocument document = new XWPFDocument(is);
//书签数据
Map<String, Object> bookTagMap = new HashMap<>();
bookTagMap.put("name", "张三");
bookTagMap.put("password", "123456");
replaceBookTag(document,bookTagMap);
//返回流
response.setHeader("content-type", "application/octet-stream");
response.setContentType("application/octet-stream;charset=UTF-8");
response.setHeader("Content-Disposition", "attachment; filename=" + new String("result.docx".getBytes("utf-8"), "ISO-8859-1"));

outputStream.flush();
outputStream.close();
document.close();
is.close();
return "Word书签替换成功！";
}准备测试文件：word书签替换测试.docx
浏览器输入：http://localhost:8080/replaceWordTag
3、Word转Pdf
controller层代码
@GetMapping("/wordToPdf")
public String wordToPdf(HttpServletResponse response) throws IOException {
String filePath = "word转换pdf测试.docx";
String outFilePath = "result.pdf";

}准备测试文件：word转换pdf测试.docx
浏览器输入：http://localhost:8080/wordToPdf
4、通过Word书签在段落中插入图片
controller层代码
@GetMapping("/replacePic")
public String replacePic() throws IOException, InvalidFormatException {
FileInputStream is = new FileInputStream("段落中插入图片测试.docx");
XWPFDocument doc = new XWPFDocument(is);
Map<String,InputStream> dataMap = new HashMap<>();

replacePicByTag(doc,dataMap);
FileOutputStream outputStream = new FileOutputStream("result.docx");
doc.write(outputStream);
outputStream.close();
doc.close();
is.close();
return "插入成功！";
}准备测试文件：段落中插入图片测试.docx
浏览器输入：http://localhost:8080/replacePic
5、生成公章
controller层代码
@GetMapping("createSeal")
public String createSeal(){
/**
* 印章配置文件
*/
SealConfiguration configuration = new SealConfiguration();
/**
* 主文字
*/
SealFont mainFont = new SealFont();
mainFont.setBold(true);
mainFont.setFontFamily("宋体");

centerFont.setFontFamily("宋体");
centerFont.setFontText("★");
centerFont.setFontSize(100);
/**
* 抬头文字
*/
SealFont titleFont = new SealFont();
titleFont.setBold(true);
titleFont.setFontFamily("宋体");
titleFont.setFontSize(22);
titleFont.setFontText("合同章");
titleFont.setMarginSize(68);
titleFont.setFontSpace(10.0);
/**
* 添加主文字
*/
configuration.setMainFont(mainFont);
/**
* 添加中心文字
*/
configuration.setCenterFont(centerFont);
/**
* 添加抬头文字
*/
configuration.setTitleFont(titleFont);
/**
* 图片大小
*/
configuration.setImageSize(300);
/**
* 背景颜色
*/
configuration.setBackgroudColor(Color.RED);
/**
* 边线粗细、半径
*/
configuration.setBorderCircle(new SealCircle(3, 140, 140));
//1.生成公章
try {
String path = System.getProperty("user.dir");
SealUtil.buildAndStoreSeal(configuration, path+"/公章.png");
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
