关于富文本html通过java生成并导出word

项目场景：

项目背景：由于前端用其他平台的缘故不支持直接引用三方库本地开发，仅可利用平台在线的方式。
现要求将合同生成word并在线下载。

问题描述

思路有很多，后端赋值并通过poi生成一篇word文档，通过前端处理富文本模板并将数据代入传至后台生成word文档

第一种思路：

1.制作word合同模板。
2.将值传递替换进模板占位符。
3.将替换完成模板导出。

这里试过这一种思路：弊端是代码量很多，在替换时会遍历每一行并将占位符进行替换，在此过程中有可能会将格式搞错，例如把下划线去掉了,改了字体颜色，多加部分空格下划线。

3. 调用部分

 // 处理导出合同
    @PostMapping("/getContractWord")
    public void getContractWord(@RequestBody Map<String, Object> jsonObject, HttpServletRequest request, HttpServletResponse response) {
        Map map =new HashMap<>();
        map.put("customerName","高密海绵厂");
        map.put("salesName","烟台顺达聚氨酯有限责任公司");
        map.put("contractNo","123456");
        log.info("============>{}",map.toString());
        DynWordUtils.process(map,"D:\\bbb.docx","D:\\aaa.doc",request,response);

    }

第二种思路

1.前端准备富文本html利用原生css处理格式。
2.前端利用es6模板语法将html中的关键字段值替换掉
3.传递后端生成word 并写入流中

1.html很多 这里只取片段 包含普通格式以及表格处理

es6只需要代码块中存在声明占位符部分，模板会自动填充

  let data =  this.value
  const date = new Date(data.createdTime); // 获取当前日期
  const year = date.getFullYear(); // 获取年份
  const month = date.getMonth() + 1; // 获取月份，需要加1，因为月份是从0开始计数的
  const day = date.getDate(); // 获取日期
  const formattedDate = `${year}年${month}月${day}日`;
  let html1 =

java部分 html转成word导出

 @PostMapping("/createWord")
    public void generateWord(@RequestBody Map<String,String> html, HttpServletRequest request, HttpServletResponse response) throws IOException {
        // 读取富文本数据
        String htmlContent = html.get("html");
        // 必须要html标识的标签 否则可能会解析不出来 
         htmlContent = "<html><head></head><body>"+htmlContent+"</body></html>";
        ByteArrayInputStream byteArrayInputStream = null;
        POIFSFileSystem poifsFileSystem = null;
        ServletOutputStream servletOutputStream = null;
        try {
            byte b[] = htmlContent.getBytes("GBK"); //这里是必须要设置编码的，不然导出中文就会乱码。
            byteArrayInputStream = new ByteArrayInputStream(b);//将字节数组包装到流中
            poifsFileSystem = new POIFSFileSystem();
            DirectoryEntry directory = poifsFileSystem.getRoot();
            directory.createDocument("WordDocument", byteArrayInputStream);
            //输出文件
            request.setCharacterEncoding("utf-8");
            response.setContentType("application/msword");//导出word格式
            response.addHeader("Content-Disposition", "attachment;filename=aaaa.doc");
            servletOutputStream = response.getOutputStream();
            poifsFileSystem.writeFilesystem(servletOutputStream);
            byteArrayInputStream.close();
            servletOutputStream.close();
            poifsFileSystem.close();
        } catch (Exception e) {
            throw e;
        }
    }

第二种思路的弊端是poifsFileSystem不支持二次修改，例如修改页边距 修改字体颜色 调整文件内容，我尝试了一下poifsFileSystem转HWPFDdocument对象没找到合适的解决方法 所以暂定不能二次修改。

最后效果
