管理员登录控制层：

public class AdminLoginController extends HttpServlet {@SneakyThrows@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {String username = req.getParameter("username");String password = req.getParameter("password");password = MyMD5Util.encrypt(password);JSONObject jsonObject = new JSONObject();HttpSession session = req.getSession();Admin admin = new Admin(username, password);Admin adminFromDB = AdminDao.findByUsernamePassword(admin);if (adminFromDB!=null){jsonObject.put("code",2000);jsonObject.put("msg","login_success");jsonObject.put("admin",adminFromDB.getUsername());jsonObject.put("flag","success");resp.getWriter().print(jsonObject);session.setAttribute("admin",adminFromDB);return;}else {jsonObject.put("code",2000);jsonObject.put("msg","no admin");jsonObject.put("admin",null);jsonObject.put("flag","fail");resp.getWriter().print(jsonObject);return;}}@Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {this.doGet(req, resp);}
}

公司入驻平台控制层：

public class BusinessRegisterController extends HttpServlet {@SneakyThrows@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {JSONObject jsonObject = new JSONObject();DiskFileItemFactory factory = new DiskFileItemFactory();ServletFileUpload upload = new ServletFileUpload(factory);req.setCharacterEncoding("UTF-8");upload.setHeaderEncoding("UTF-8");List<FileItem> items = upload.parseRequest(req);StringBuffer sb = new StringBuffer();String companyFile = null;for (FileItem item : items) {String name = item.getFieldName();InputStream inputStream = item.getInputStream();if (!name.equals("companyFile")){String string = item.getString();string = new String(string.getBytes("ISO8859_1"), StandardCharsets.UTF_8);sb.append(string+"&&");}else {String[] split = sb.toString().split("&&");String companyName = split[0];String companyId = split[1];String path=req.getServletContext().getRealPath("/");System.out.println(path);String fieldName = companyName+"_"+companyId+"_"+item.getName();String filePath = path+fieldName;companyFile = fieldName;File file = new File(filePath);BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);FileOutputStream fileOutputStream = new FileOutputStream(file);int line;while ((line = bufferedInputStream.read())!=-1){fileOutputStream.write(line);}fileOutputStream.flush();fileOutputStream.close();bufferedInputStream.close();}}String[] split = sb.toString().split("&&");String companyName = split[0];String companyId = split[1];String password = split[2];String password2 = MyMD5Util.encrypt(password);BusinessVO businessVO = new BusinessVO(companyName, companyId, password2, companyFile);try {int i = BusinessDao.insertToVerify(businessVO);if (i == 1){jsonObject.put("code",2000);jsonObject.put("msg","waiting verify");//企业用户注册完，等待管理员审核resp.getWriter().print(jsonObject);return;}else {jsonObject.put("code",2000);jsonObject.put("msg","companyId exist");//企业id已存在resp.getWriter().print(jsonObject);return;}} catch (SQLException throwables) {throwables.printStackTrace();jsonObject.put("code",5000);jsonObject.put("msg","server error");resp.getWriter().print(jsonObject);return;}}@Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {this.doGet(req, resp);}
