前后端分离项目之数据导出为word实例

1.后台restful api，组装文件输出流对象到response响应包输出到前端(vue+webpack node管理)。

后台接口：根据projectId查询相关数据，并将相关字段封装到word模板中，最后用流输出文件。

控制层代码

@RequestMapping("/exportToWord")
@ResponseBody
public void exportToWord(HttpServletRequest request,
HttpServletResponse response,
@RequestParam(value = "projectId", required = true) String projectId) {
try {
String path = request.getSession().getServletContext().getRealPath("\\");
projectDocService.exportToWord(response,projectId,path);
} catch (Exception e) {
logger.error("事项导出成word失败:", e);
}
}

业务层代码

public void exportToWord(HttpServletResponse response,String projectId,String path) throws Exception{
HashMap<String,Object> params=new HashMap<String,Object>();
params.put("projectId", projectId);
HashMap<String, Object> projectMap = projectDao.queryProjectDetailByPid(params);
if(projectMap!=null){
// 导出基本信息
operatorProject(projectMap, path);
String downpath = path + "FileDownload/govsdm/Download/project.docx";
String erweimapath = path + "FileDownload/govsdm/QRCode/project.jpg";
String srcpath = path + "FileDownload/govsdm/Export/project.docx";
FileInputStream inputStream = new FileInputStream(erweimapath);
Map<String, FileInputStream> maps = new HashMap<String, FileInputStream>(
0);
maps.put("$erweima", inputStream);
CustomXWPFDocument customXWPFDocument = new CustomXWPFDocument();
// 插入二维码
customXWPFDocument.searchAndReplaceImg(srcpath, downpath,
erweimapath, maps);

download(downpath, response, projectMap.get("projectName").toString());
}
}

导出的word模板如下图：

public void operatorProject(Map<String, Object> projectMap, String path) throws Exception {
HashMap<String, Object> map = new HashMap<String, Object>();
//事项基本信息
map.put("${projectNo}", projectMap.get("projectNo"));

最后输出文件流

public HttpServletResponse download(String path, HttpServletResponse response, String projectname) throws Exception {
// path是指欲下载的文件的路径。
File file = new File(path);
// 以流的形式下载文件。
InputStream fis = new BufferedInputStream(new FileInputStream(path));
byte[] buffer = new byte[fis.available()];
fis.read(buffer);
fis.close();
// 清空response
response.reset();
// 设置response的Header
response.addHeader("Content-Disposition", "attachment;filename="
+ new String((projectname + ".docx").getBytes("gbk"),
"iso-8859-1"));
response.addHeader("Content-Length", "" + file.length());
OutputStream toClient = new BufferedOutputStream(
response.getOutputStream());
response.setContentType("application/octet-stream");
toClient.write(buffer);
toClient.flush();
toClient.close();
return response;
}

前端vue代码片段；

<Button type="warning" size="small" @click="exports(item.projectId)" icon="share" v-if="btnData.indexOf('export')!==-1">导出</Button>

js代码

//导出
exports(projectId){
let token = localStorage.getItem('token');

//自定义form标签，初始化相关参数
var form = $("<form>");
form.attr('style', 'display:none');
form.attr('target', '');
form.attr('method', 'post');
form.attr('action', window.config.api + '/projectDocController/exportToWord.do');

var input1 = $('<input>');
input1.attr('type', 'hidden');
input1.attr('name', 'projectId');
input1.attr('value', projectId);

var input2 = $('<input>');
input2.attr('type', 'hidden');
input2.attr('name', 'token');
input2.attr('value', token);

$('body').append(form);
form.append(input1);
form.append(input2);

form.submit();
form.remove();
}

小结：针对文件流的操作，尽量用提交form表单的形式处理请求。
