模版文件(以截图形式展示）

结果
 

1.导入对应依赖

         <!-- hutool工具类 -->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>4.6.3</version>
        </dependency>

        <!--word模板数据解析-->
        <dependency>
            <groupId>com.deepoove</groupId>
            <artifactId>poi-tl</artifactId>
            <version>1.9.0-beta</version>
        </dependency>
        <!-- word/pdf操作 -->
        <dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-words</artifactId>
            <version>18.8</version>
        </dependency>

2.将工具类导入

 3.加入破解程序 license.xml文件
 

<?xml version="1.0" encoding="UTF-8" ?>

    <Data>
        <Products>
            <Product>Aspose.Total for Java</Product>

4.处理对应逻辑并赋值

private void download(DataHandlerDto dataHandlerDto) throws IOException {

        Map<String,Object> map = new HashMap<String,Object>();
        map.put("caption", dataHandlerDto.getCaption());
        map.put("dealerName", dataHandlerDto.getDealerName());
        map.put("linkMan", dataHandlerDto.getLinkMan());
        map.put("mobile", dataHandlerDto.getMobile());
        map.put("time", dataHandlerDto.getTime());
        map.put("address", dataHandlerDto.getAddress());
        map.put("list", dataHandlerDto.getList());
        //需要填充到word中的图片数据
        //模板文件流
        InputStream tempStream = new FileInputStream(new File("D://hh/inspectionDeliver1.docx"));

        String time = StringUtils.isBlank(dataHandlerDto.getTime()) ? " " : dataHandlerDto.getTime().split(" ")[0];
        //填充word:
        byte[] bytes = WordUtil.fillWord(map, tempStream);
        //word转pdf:
        File pdfFile = new File("D://dealerDeliver/"+time+"_"+dataHandlerDto.getDealerName() +".pdf");
        WordUtil.wordToPDF(new ByteArrayInputStream(bytes),new FileOutputStream(pdfFile));
    }
