Java实战之兼职平台系统的实现 Java实战之兼职平台系统的实现

一、项目运行
二、效果图
三、核心代码

登录控制层
管理员登录控制层
提交个人简介控制层

一、项目运行环境配置：
Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）
项目技术：
HTML +Springboot+ SpringMVC + MyBatis + ThymeLeaf + JavaScript + JQuery + Ajax + maven等等.

登录控制层

/** * @Author yy * @Description 登录 * @Date 2022.2.17 */ public class LoginController extends HttpServlet {@Overrideprotected void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {JSONObject jsonObject = new JSONObject(); String username = req.getParameter("username"); String password = req.getParameter("password"); resp.setCharacterEncoding("UTF-8"); HttpSession session = req.getSession(); if (StringUtils.isBlank(username) || StringUtils.isBlank(password)) {jsonObject.put("code", 2000); jsonObject.put("flag", "fail"); jsonObject.put("user", null); jsonObject.put("msg", "usernameOrPasswordIsBank"); //用户名密码不能为空resp.getWriter().print(jsonObject); return; }password = MyMD5Util.encrypt(password); System.out.println(password); BusinessUserVO businessUserVO = new BusinessUserVO(); businessUserVO.setUsername(username); businessUserVO.setPassword(password); StudentUserVO studentUserVO = new StudentUserVO(); studentUserVO.setUsername(username); studentUserVO.setPassword(password); String flag1 = null; String flag2 = null; try {flag1 = BusinessUserDao.selectUsername(businessUserVO); if ("ok".equals(flag1)) {//企业用户名存在BusinessUserDTO businessUserDTO = BusinessUserDao.select(businessUserVO); if (businessUserDTO != null) {jsonObject.put("code", 2000); jsonObject.put("flag", "success"); //登录成功jsonObject.put("user", businessUserDTO); jsonObject.put("msg", "login_success"); session.setAttribute("businessUser",businessUserDTO); resp.getWriter().print(jsonObject); return; } else {jsonObject.put("code", 2000); jsonObject.put("flag", "fail"); //登录失败jsonObject.put("user", null); jsonObject.put("msg", "passwordError"); //密码错误resp.getWriter().print(jsonObject); return; }}flag2 = StudentUserDao.selectUsername(studentUserVO); if ("ok".equals(flag2)) {//学生用户名存在StudentUser studentUser = StudentUserDao.select(studentUserVO); if (studentUser != null) {jsonObject.put("code", 2000); jsonObject.put("flag", "success"); //登录成功jsonObject.put("user", studentUser); jsonObject.put("msg", "login_success"); session.setAttribute("studentUser",studentUser); resp.getWriter().print(jsonObject); return; } else {jsonObject.put("code", 2000); jsonObject.put("flag", "fail"); //登录失败jsonObject.put("user", null); jsonObject.put("msg", "passwordError"); //密码错误resp.getWriter().print(jsonObject); return; } }//用户名不存在，前往注册jsonObject.put("code", 2000); jsonObject.put("flag", "fail"); //登录失败jsonObject.put("user", null); jsonObject.put("msg", "usernameIsNotExist"); //密码错误resp.getWriter().print(jsonObject); return; } catch (SQLException throwables) {throwables.printStackTrace(); }return; } @Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException {doGet(req, resp); }}

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); }}

提交个人简介控制层

public class SubmitResumeController 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 items = upload.parseRequest(req); StringBuffer sb = new StringBuffer(); String resumeFile = null; for (FileItem item : items) {String name = item.getFieldName(); InputStream inputStream = item.getInputStream(); if (!name.equals("resumeFile")){String string = item.getString(); string = new String(string.getBytes("ISO8859_1"), StandardCharsets.UTF_8); sb.append(string+"&&"); }else {String[] split = sb.toString().split("&&"); String studentName = split[0]; String studentUsername = split[1]; String recruitInfoId = split[2]; String path=req.getServletContext().getRealPath("/"); String fieldName = studentName+"_"+studentUsername+"_"+recruitInfoId+"_"+item.getName(); String filePath = path+fieldName; resumeFile = 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 studentName = split[0]; String studentUsername = split[1]; String recruitInfoId = split[2]; String applyPosition = split[3]; String phoneNum = split[4]; String email = split[5]; Resume resume = new Resume(studentUsername, Integer.parseInt(recruitInfoId), studentName, applyPosition, phoneNum, email, resumeFile); int insert = ResumeDao.insert(resume); if (insert == 1){jsonObject.put("code",2000); jsonObject.put("msg","add success"); jsonObject.put("flag","success"); jsonObject.put("data",resume); resp.getWriter().print(jsonObject); return; }else {jsonObject.put("code",2000); jsonObject.put("msg","add fail"); jsonObject.put("flag","fail"); jsonObject.put("data",null); resp.getWriter().print(jsonObject); } } @Overrideprotected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {this.doGet(req, resp); }}
