Poi-tl参考文档地址：http://deepoove.com/poi-tl/1.8.x/#hack-loop-table

1. 依赖引入：

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

  <dependency>
      <groupId>com.aspose</groupId>
      <artifactId>aspose-words</artifactId>
      <version>18.2</version>
      <classifier>jdk16</classifier>
  </dependency>

  <dependency>
      <groupId>com.deepoove</groupId>
      <artifactId>poi-tl</artifactId>
      <version>1.8.2</version>
  </dependency>

<!-- 通过Maven库拿不到，就加下面的配置 -->
<repositories>
     <repository>
         <id>AsposeJavaAPI</id>
         <name>Aspose Java API</name>
         <url>https://repository.aspose.com/repo/</url>
     </repository>

     </pluginRepository>
 </pluginRepositories>

2. word模板配置：

        绿色部分是直接渲染的，对应map中的key-value，蓝色部分是绑定collections对象，进行遍历循环集合数据

3. 示例demo:

public static void main(String[] args) throws Exception {
       public static void main(String[] args) throws Exception {
        ByteArrayOutputStream docOutput = new ByteArrayOutputStream();

        Map<String, Object> map = new HashMap<>(3);
        map.put("zfkp", "AAAA");
        map.put("kpjg", "123");
        map.put("kpr", "李四");

        List<Map> list = new ArrayList<>();
        Map<String, Object> map1 = new HashMap<>(3);
        map1.put("number", 1);
        map1.put("kprlist", "xxxa");
        map1.put("fs", 17);
        Map<String, Object> map2 = new HashMap<>(3);
        map2.put("number", 2);
        map2.put("kprlist", "xxxa3aa");
        map2.put("fs", 10);
        list.add(map1);
        list.add(map2);
        //列表集合数据
        map.put("collections", list);

        HackLoopTableRenderPolicy policy = new HackLoopTableRenderPolicy();
        Configure config = Configure.newBuilder()
                //绑定集合数据
                .bind("collections", policy).build();

        System.out.println(map);
        //加载配置的word模板
        XWPFTemplate template = XWPFTemplate.compile("C:\\Users\\DELL\\Desktop\\kpwtlb.docx", config);

        template.render(map);
        //写入word，swapStream可输出word文档
        template.write(docOutput);
        ByteArrayInputStream swapStream = new ByteArrayInputStream(docOutput.toByteArray());

        //word转PDF
        Document doc = new Document(swapStream);
        ByteArrayOutputStream pdfOutput = new ByteArrayOutputStream();
        doc.save(pdfOutput, SaveFormat.PDF);

        ByteArrayInputStream pdfinput = new ByteArrayInputStream(pdfOutput.toByteArray());
        FileUtil.inputStreamToFile(pdfinput, "C:\\Users\\DELL\\Desktop\\", "123.pdf");
    }

4 . 效果图

        转换的pdf有水印，去水印很方便, 加载License（要买）即可 封装一个工具类
