查询出的list集合中的数据导出到word模板

1.背景

  在项目中有个需求是将查询出的领用借出单实现打印功能.一般的实现思路是先将领用单导出成word,再将其转成pdf,上传到ftp(这一步看需求可以替换成本地或者其他地方)获取地址,将地址返回给前端.前端得到这个利用浏览器自带的pdf的打印功能,实现打印.

2.编写导出成word模板(以领用单为例)

 

注:在替换过程中${receiveNo}可能不会被替换,如果 出现这种情况,是模板有问题,将${receiveNo}整个复制到txt,再复制回去即可.

3.controller层

 /**
 *  打印预览--先导出成docx,在上传到ftp,得到ftp地址进行显示
 */
@RequestMapping(value = "/printPreview/{appId}", method = {RequestMethod.POST, RequestMethod.GET })
@ResponseBody
public WebResponse printPreview(
        HttpServletRequest request,
        HttpServletResponse response,
        @RequestParam(value = "appId", required = false) String appId,
        @RequestParam(value = "receiveNo", required = false) String receiveNo

){

    Pager pager;
    Map<String, Object> map = new HashMap<>();
    try {
        String path = request.getSession().getServletContext().getRealPath("/") + "rpt_template" + "/" + "word" + "/" + "receiveInfo.docx";
        String newPath = request.getSession().getServletContext().getRealPath("/") + "rpt_template" + "/" + "word" + "/" + "receiveInfoNW.docx";
        Integer page = 1;
        Integer rows = 99;
        pager = receiveService.getReceiveInfo(receiveNo, page, rows);
        FileUtils.copyFile(new File(newPath), new File(path));
        CustomXWPFDocument doc = receiveService.receiveInfoPdf(pager.getRows(), path);
        map = receiveService.handlePdf(request, doc);
    } catch (Exception e) {
        e.printStackTrace();
        return this.buildResponse("705", e.getMessage());
    }
    return buildResponse(map);

}

注:模板要保存两份,不然会出现上次导出的会累加,所以要用新的模板替换.

4.service层(service层主要替换模板信息)

public  CustomXWPFDocument receiveInfoPdf(List<ReceiveInfoResult> info,String wordPath){
    Map<String, Object> data = new HashMap<>();
    data.put("${receiveNo}", info.get(0).getReceiveNo());
    data.put("${sectionName}", info.get(0).getSectionName());
    data.put("${receiveName}", info.get(0).getReceiveName());
    data.put("${receiveTime}", info.get(0).getReceiveTime());
    List<Map<String, Object>> receiveInfoList = new ArrayList<Map<String, Object>>();
    for (int i = 0; i < info.size(); i++) {
        ReceiveInfoResult receiveInfo = info.get(i);
        Map<String, Object> content = new HashMap<>();
        content.put("序号", String.valueOf(i + 1));
        content.put("工器具类型", receiveInfo.getInstrumentTypeBig());
        content.put("工器具名称", receiveInfo.getInstrumentName());
        content.put("规格型号", receiveInfo.getInstrumentModel());
        content.put("RFID编码", receiveInfo.getRfid());
        content.put("位置", receiveInfo.getContainerNumber());
        content.put("归还时间", receiveInfo.getInTime());
        content.put("状态", receiveInfo.getInState());
        receiveInfoList.add(content);
    }
    data.put("${contentList}", receiveInfoList);
    CustomXWPFDocument doc = WorderToNewWordUtils.changWordReceiveInfo(wordPath, data);
    return doc;
}

5.其中用到的主要的util类

  根据领用单模板生成word文档

/**
 * 根据领用单模板生成word文档
 * @param inputUrl 模板路径
 * @param textMap 需要替换的文本内容
 * @return
 */
public static CustomXWPFDocument changWordReceiveInfo(String inputUrl, Map<String, Object> textMap) {
    CustomXWPFDocument document = null;
    try {
        //获取docx解析对象
        document = new CustomXWPFDocument(POIXMLDocument.openPackage(inputUrl));

        //解析替换文本段落对象
        try {
            WorderToNewWordUtils.changeText(document,textMap);
        } catch (Exception e) {
            e.printStackTrace();
        }
        //解析替换表格对象
        WorderToNewWordUtils.changeTableReceive(document,textMap);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return document;
}

 替换表格对象方法

/**
 * 替换表格对象方法
 * @param document docx解析对象
 * @param textMap 需要替换的信息集合
 */
public static void changeTableReceive(CustomXWPFDocument document, Map<String, Object> textMap){
    //获取表格对象集合
    List<XWPFTable> tables = document.getTables();
    //动态添加 问题列表行
    XWPFTable table1 = tables.get(0);//获取第一个表格
     // XWPFTableRow table1 = tables.get(0).getRow(0);
    List<Map<String, Object>> contentList = (List<Map<String, Object>>) textMap.get("${contentList}");
    if (contentList != null && contentList.size()>0){
        for(int i=0;i<contentList.size();i++){
            XWPFTableRow row = table1.insertNewTableRow(1+i);//为第2+i行向下添加一个新行
            //XWPFTableRow row = table1;
            row.createCell().setText((String) contentList.get(i).get("序号"));//添加第二个列
            row.createCell().setText((String) contentList.get(i).get("工器具类型"));//添加第三个列
            row.createCell().setText((String) contentList.get(i).get("工器具名称"));//添加第四个列
            row.createCell().setText((String) contentList.get(i).get("规格型号"));//添加第五个列
            row.createCell().setText((String) contentList.get(i).get("RFID编码"));//添加第五个列
            row.createCell().setText((String) contentList.get(i).get("位置"));//添加第五个列
            row.createCell().setText((String) contentList.get(i).get("归还时间"));//添加第五个列
            row.createCell().setText((String) contentList.get(i).get("状态"));//添加第五个列
        }
    }

}

 转换成pdf,上传到ftp

/**
 *
 * @param request
 * @param doc
 * @return 获取PDF路径
 * @throws Exception
 */
public   Map<String,Object> handlePdf(HttpServletRequest request, CustomXWPFDocument doc) throws Exception {
    //生成地址   创建PDF路径   生成wordPath 开始
    String newWordPath = request.getSession().getServletContext().getRealPath("/") +
            "rpt_template/temp_file/" + UUID.randomUUID().toString() + ".docx";
    File newFile = new File(newWordPath);
    newFile.createNewFile();//新增一个文件
    FileOutputStream fopts = new FileOutputStream(newFile);
    doc.write(fopts);
    fopts.close();
    doc.close();
    //生成wordPath 结束
    //创建返回map
    Map<String, Object> resultMap = new HashMap<>();
    //创建PDF路径
    String pdfTeamPath = request.getSession().getServletContext().getRealPath("/") + "rpt_template" + "/" + "temp_file" + "/" + UUID.randomUUID() + ".pdf";
    //word形式转换成pdf(fileUrl文件路径/pdfTeamPath转PDF路径)
    FileUtil.doc2pdf(newWordPath, pdfTeamPath);
    //上传ftp 服务器
    File pdfFile = new File(pdfTeamPath);
    String pdfPath = FTPUtil.uploadFile("files/pdf/", pdfFile, pdfFile.getName());
    String pdfUrl = ConstantsUtil.photoPath + pdfPath;
    //获取路径
    resultMap.put("fileUrl", pdfUrl);
    //删除文件 pdfTeamPath
    ExportSafetyNoticeRest.deleteFile(pdfTeamPath);
    ExportSafetyNoticeRest.deleteFile(newWordPath);
    resultMap.put("worfUrl", newWordPath);
    return resultMap;
}

 end!
