## 一、新建Word模板 ##

![模板文档][cd13d63a32e743fda142a61eb37a9e91.png]  
在你需要动态生成的内容使用\{field\}作为占位符，后面代码扫描到就将占位符换成自己的动态内容。

## 二、导入依赖 ##

<dependency>
             <groupId>org.apache.poi</groupId>
             <artifactId>poi</artifactId>
             <version>4.1.2</version>
         </dependency>
         <dependency>
             <groupId>org.apache.poi</groupId>
             <artifactId>poi-ooxml</artifactId>
             <version>4.1.2</version>
         </dependency>
    
         <dependency>
             <groupId>commons-io</groupId>
             <artifactId>commons-io</artifactId>
             <version>2.11.0</version>
         </dependency>

## 三、编写代码 ##

### 1、替换文字 ###

代码如下（示例）：

public static void main(String[] args) {
        
            try {
        
                String templatePath = "C:\\Users\\Administrator\\Desktop\\test3.docx";
                String outputPath = "C:\\Users\\Administrator\\Desktop\\output.docx";
    
                InputStream inputStream = new FileInputStream(templatePath);
                XWPFDocument document = new XWPFDocument(inputStream);
    
                Map<String, String> hashMap = new HashMap<>();
                hashMap.put("name", "JUVENILESS");
                hashMap.put("gender", "男");
                hashMap.put("schoolNumber", "13123132");
                hashMap.put("qq", "123123");
                hashMap.put("nativePlace", "测试");
                hashMap.put("profession", "测试啊");
                hashMap.put("birth", "2025-10");
                hashMap.put("dorm", "I123");
                hashMap.put("cellNumber", "12345678911");
                hashMap.put("introduction", "简单的自我介绍");
                hashMap.put("futureOutlook", "简单的对未来发展");
                hashMap.put("award", "拿过的奖项拿过的奖项");
                hashMap.put("department","部门");
                hashMap.put("year","年份");
                // 替换占位符
                replacePlaceholdersInDocument(document, hashMap);
    
                // 插入图片
                insertPictureInTableCell(document, "{picture}", picturePath);
    
                // 保存生成的文档
                FileOutputStream outputStream = new FileOutputStream(outputPath);
                document.write(outputStream);
                outputStream.close();
    
                System.out.println("生成的文档已保存。");
            } catch (Exception e) {
        
                e.printStackTrace();
            }
        }
    
        private static void replacePlaceholdersInDocument(XWPFDocument document, Map<String, String> hashMap) {
        
            for (XWPFParagraph paragraph : document.getParagraphs()) {
        
                replaceParagraphPlaceholders(paragraph, hashMap);
            }
    
            for (XWPFTable table : document.getTables()) {
        
                for (XWPFTableRow row : table.getRows()) {
        
                    for (XWPFTableCell cell : row.getTableCells()) {
        
                        for (XWPFParagraph paragraph : cell.getParagraphs()) {
        
                            replaceParagraphPlaceholders(paragraph, hashMap);
                        }
                    }
                }
            }
        }

直接运行即可。运行结果图为：

### 2、插入图片 ###

这里我是查找表格的单元格里的占位符。  
![图片文档模板][a7ef722219724c45857f0a720a0676dc.png]

代码如下（示例）：

static String picturePath = "C:\\Users\\Administrator\\Desktop\\picture.jpg";
    
      public static void main(String[] args) {
        
    
            try {
        
                String templatePath = "C:\\Users\\Administrator\\Desktop\\test4.docx";
                String outputPath = "C:\\Users\\Administrator\\Desktop\\output1.docx";
    
                InputStream inputStream = new FileInputStream(templatePath);
                XWPFDocument document = new XWPFDocument(inputStream);
                
                // 插入图片
                insertPictureInTableCell(document, "{picture}", picturePath);
    
                // 保存生成的文档
                FileOutputStream outputStream = new FileOutputStream(outputPath);
                document.write(outputStream);
                outputStream.close();
                System.out.println("生成的文档已保存。");
            } catch (Exception e) {
        
                e.printStackTrace();
            }
        }
    
        private static void insertPictureInTableCell(XWPFDocument document, String placeholder, String picturePath) throws Exception {
        
            List<XWPFTable> tables = new ArrayList<>(document.getTables());
            for (XWPFTable table : tables) {
        
                List<XWPFTableRow> rows = new ArrayList<>(table.getRows());
                for (XWPFTableRow row : rows) {
        
                    List<XWPFTableCell> cells = new ArrayList<>(row.getTableCells());
                    for (XWPFTableCell cell : cells) {
        
                        List<XWPFParagraph> paragraphs = new ArrayList<>(cell.getParagraphs());
                        for (XWPFParagraph paragraph : paragraphs) {
        
                            List<XWPFRun> runs = new ArrayList<>(paragraph.getRuns());
                            for (XWPFRun run : runs) {
        
                                String text = run.getText(0);
                                if (text != null && text.contains(placeholder)) {
        
                                    int index = text.indexOf(placeholder);
                                    if (index >= 0) {
        
                                        // 移除占位符
                                        run.setText(text.replace(placeholder, ""), 0);
    
                                        // 在当前段落中插入图片
                                        XWPFRun pictureRun = paragraph.createRun();
                                        try (FileInputStream pictureInputStream = new FileInputStream(picturePath)) {
        
                                            pictureRun.addPicture(pictureInputStream, Document.PICTURE_TYPE_JPEG, "picture.jpg", Units.toEMU(200), Units.toEMU(200));
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }

生成的结果如下：

这里我发现图片的尺寸没法保证跟单元格大小一致，也尝试过很多种方法都不太行。哪位大佬尝试尝试哈哈哈哈
