手机移动端接口

Posted 2021-03-04 zeevy

在项目开发中，可能移动端需要请求查询数据或者向数据表中插入数据，这时需要编写接口给移动端调用。

//查询
@RequestMapping("/query")
//通过request传递请求参数
    public String query(Page page, HttpServletRequest request) {
        Map<String, Object> keyMap = new HashMap<String, Object>();    
        List<Map<String, Object>> rtnList = new ArrayList<Map<String, Object>>();
        try {
                        获取查询条件
            keyMap.put("carNumber", request.getParameter("CarsNo"));
            List<Map<String, Object>> vehicleRegulationList = vehicleRegulationService.findAll(page, keyMap);
            for(Map<String, Object> vehicleRegulation : vehicleRegulationList) {
            Map<String, Object> map = new HashMap<>();
            map.put("CarsNo", vehicleRegulation.get("carNumber"));
            map.put("PhoneNo", vehicleRegulation.get("phone"));
            map.put("CarsType", vehicleRegulation.get("carType"));
            map.put("ViolationPlace", vehicleRegulation.get("siteVio"));
            map.put("ViolationType", vehicleRegulation.get("typeVio"));
            map.put("datetimeVio", vehicleRegulation.get("datetimeVio"));
            rtnList.add(map);
            }
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
               //返回json格式数据
        return AjaxUtilNew.getJson("200", "查询成功", rtnList);
    }

}                    

//手机端上传图片
@RequestMapping("/upload")
    public String upload(HttpServletRequest request) {
        String url = "";
        try {
                        //接受图片流
            MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
                          //将图片流转成MultipartFile，有可能上传多张图片
            Map<String, MultipartFile> files = multiRequest.getFileMap();
            //将图片上传到图片服务器并获取图片路径
                        for (MultipartFile multipartFile : files.values()) {
                if (multipartFile.isEmpty()) {
                    continue;
                }
                String fileName = multipartFile.getOriginalFilename();
                if (fileName == null || fileName.trim().equals("")) {
                    continue;
                }
                Integer index = fileName.lastIndexOf("\");
                String newStr = "";
                if (index > -1) {
                    newStr = fileName.substring(index + 1);
                } else {
                    newStr = fileName;
                }
                if (!newStr.equals("")) {
                    fileName = newStr;
                }
                String preFixName = fileName.substring(0, fileName.lastIndexOf("."));
                String suffixName = fileName.substring(fileName.lastIndexOf(".") + 1);
                String prefileName = preFixName + "_" + DateTools.getFullNowDateTimeErp() + "." + suffixName;
          
                String filePath = new File(System.getProperty("user.dir")).getParent() + "/webapps/fileApp";
                String realPath = filePath + ("/uploadFiles/vehicleRegulation/"
                        + "mobileUpload" + "/" + UUID.randomUUID());
                File upload = new File(realPath);
                log.info(realPath);
                if (!upload.exists()) {
                    upload.mkdirs();
                }
                File dest = new File(upload.getAbsolutePath() + "/" + prefileName);
                 multipartFile.transferTo(dest);
                url = url + "," + upload.getAbsolutePath() + "/" + prefileName;
            }

        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
                //返回图片url，多个图片就将多个url拼接返回给调用端
        return url;
