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; }
1 //手机端接受数据,插入数据库 2 @RequestMapping("/receive") 3 public void receive(HttpServletRequest request) { 4 VehicleRegulationEntity vehicleRegulation = new VehicleRegulationEntity(); 5 User user = new User(); 6 //通过request获取参数 7 user.setStrName(request.getParameter("UploadPerNmae")); 8 user.setStrAccount(request.getParameter("UploadPerNo")); 9 Company company = new Company(); 10 company.setId("1"); 11 String id = UUIDUtil.getUUID(); 12 vehicleRegulation.setId(id); 13 vehicleRegulation.setCarNumber(request.getParameter("CarsNo")); 14 vehicleRegulation.setPhone(request.getParameter("PhoneNo")); 15 vehicleRegulation.setCarType(request.getParameter("CarsType")); 16 vehicleRegulation.setSiteVio(request.getParameter("ViolationPlace")); 17 vehicleRegulation.setTypeVio(request.getParameter("ViolationType")); 18 vehicleRegulation.setRemark(request.getParameter("Remark")); 19 vehicleRegulation.setCreateDateTime(DateTools.getFullNowDateTime()); 20 vehicleRegulation.setCreateUser(user); 21 vehicleRegulation.setCompany(company); 22 try { 23 vehicleRegulationService.createMobile(vehicleRegulation); 24 } catch (Exception e) { 25 log.error(e.getMessage(), e); 26 } 27 NjAttach attach = new NjAttach(); 28 String[] url = request.getParameter("url").split(","); 29 for(int i = 0; i < url.length; i++) { 30 if(url[i].isEmpty()) { 31 continue; 32 } 33 String idString = UUIDUtil.getUUID(); 34 attach.setId(idString); 35 attach.setStrPath(url[i]); 36 attach.setRelativedId(id); 37 attach.setCompany(company); 38 attach.setCreateUser(user); 39 int j = url[i].lastIndexOf('/'); 40 String strName = url[i].substring(j+1); 41 attach.setStrName(strName); 42 attach.setCreateDateTime(DateTools.getFullNowDateTime()); 43 try { 44 attachService.createMobile(attach); 45 } catch (Exception e) { 46 log.error(e.getMessage(), e); 47 } 48 } 49 }
