Java|Java 实战项目之毕业设计管理系统的实现流程 Java实战项目之毕业设计管理系

一、项目简述功能包括：该系统不错分为学生，教师，管理员，教导主任四种角色，包括学生管理，教师管理，学生选题，教师选题，主任审核，管理员审核，开题报告，中期检查，论文提交，文件管理等等非常不错。
二、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： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。

用户管理操作控制层：

/** * 用户管理操作 */@Controller@RequestMapping("/user")public class UserController { @Autowiredprivate UserService userService; /*** 用户添加页面* @return*/@GetMapping("/add")public String create() {return "user/add"; } /*** 用户添加操作* @param user* @return*/@PostMapping("/add")@ResponseBodypublic Map add(@RequestBody User user) {if(StringUtils.isEmpty(user.getUserName())){return MapControl.getInstance().error("请填写用户名").getMap(); }if(StringUtils.isEmpty(user.getName())){return MapControl.getInstance().error("请填写名称").getMap(); }if(StringUtils.isEmpty(user.getUserPwd())){return MapControl.getInstance().error("请填写密码").getMap(); }int result = userService.create(user); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } /*** 根据id删除* @param id* @return*/@PostMapping("/delete/{id}")@ResponseBodypublic Map delete(@PathVariable("id") Integer id) {int result = userService.delete(id); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } //批量删除@PostMapping("/delete")@ResponseBodypublic Map delete(String ids) {int result = userService.delete(ids); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } /*** 编辑用户信息操作* @param user* @return*/@PostMapping("/edit")@ResponseBodypublic Map edit(@RequestBody User user) {if(StringUtils.isEmpty(user.getUserName())){return MapControl.getInstance().error("请填写用户名").getMap(); }if(StringUtils.isEmpty(user.getName())){return MapControl.getInstance().error("请填写名称").getMap(); }if(StringUtils.isEmpty(user.getUserPwd())){return MapControl.getInstance().error("请填写密码").getMap(); }int result = userService.update(user); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } /*** 根据id查询，跳转修改页面* @param id* @param modelMap* @return*/@GetMapping("/edit/{id}")public String edit(@PathVariable("id") Integer id, ModelMap modelMap) {User user = userService.detail(id); modelMap.addAttribute("user", user); return "user/edit"; } //查询所有@PostMapping("/query")@ResponseBodypublic Map query(@RequestBody User user) {List list = userService.query(user); Integer count = userService.count(user); return MapControl.getInstance().success().page(list, count).getMap(); } //跳转列表页面@GetMapping("/list")public String list() {return "user/list"; } }

跳转首页判断以及数据展示图表：

公告管理控制器：

/** * 公告管理控制器 */@Controller@RequestMapping("/notice")public class NoticeController { @Autowiredprivate NoticeService noticeService; //跳转添加页面@GetMapping("/add")public String add() {return "notice/add"; } /*** 公告添加* @param notice* @return*/@PostMapping("/add")@ResponseBodypublic Map add(Notice notice, HttpServletRequest request) {if(StringUtils.isEmpty(notice.getTitle())){return MapControl.getInstance().error("请填写公告标题").getMap(); }if(StringUtils.isEmpty(notice.getContent())){return MapControl.getInstance().error("请填写公告内容").getMap(); }User user = (User) request.getSession().getAttribute("user"); notice.setAuthor(user.getUserName()); notice.setAuth("1"); int result = noticeService.create(notice); if (result <= 0) {//新增失败return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } //根据id删除@PostMapping("/delete/{id}")@ResponseBodypublic Map delete(@PathVariable("id") Integer id) {int result = noticeService.delete(id); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } //批量删除@PostMapping("/delete")@ResponseBodypublic Map delete(String ids) {int result = noticeService.delete(ids); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } /*** 修改公告操作* @param notice* @return*/@PostMapping("/edit")@ResponseBodypublic Map edit(@RequestBody Notice notice) {if(StringUtils.isEmpty(notice.getTitle())){return MapControl.getInstance().error("请填写公告标题").getMap(); }if(StringUtils.isEmpty(notice.getContent())){return MapControl.getInstance().error("请填写公告内容").getMap(); }int result = noticeService.update(notice); if (result <= 0) {return MapControl.getInstance().error().getMap(); }return MapControl.getInstance().success().getMap(); } //根据id查询，跳转修改页面@GetMapping("/edit/{id}")public String edit(@PathVariable Integer id, ModelMap modelMap) {//查询要修改的老师Notice notice = noticeService.detail(id); modelMap.addAttribute("notice", notice); return "notice/edit"; }//根据id查询，跳转添加页面@GetMapping("/look/{id}")public String look(@PathVariable Integer id, ModelMap modelMap) {Notice notice = noticeService.detail(id); modelMap.addAttribute("notice", notice); return "notice/look"; } //查询所有@PostMapping("/query")@ResponseBodypublic Map query(@RequestBody Notice notice) {List list = noticeService.query(notice); Integer count = noticeService.count(notice); return MapControl.getInstance().success().put("data", list).put("count", count).getMap(); } //跳转列表页面@GetMapping("/list")public String list() {return "notice/list"; }}

登陆用户判断业务控制层：

@Controllerpublic class LoginController { @Autowiredprivate UserService userService; @Autowiredprivate TeacherService teacherService; @Autowiredprivate StudentService studentService; //跳转登录页面@GetMapping("/login")public String login() {return "login"; } //登录操作@PostMapping("/login")@ResponseBodypublic Map login(String userName, String password, String captcha, String type, HttpSession session) {//判断用户名、密码、用户类型、验证码是否为空if (StringUtils.isEmpty(userName) || StringUtils.isEmpty(password) || StringUtils.isEmpty(captcha) || StringUtils.isEmpty(type)) {return MapControl.getInstance().error("用户名或密码不能为空").getMap(); }//获取系统生成的验证码String _captcha = (String) session.getAttribute("captcha"); //先判断验证码是否正确if (!(captcha.toLowerCase()).equals(_captcha.toLowerCase())) {//验证码错误return MapControl.getInstance().error("验证码错误").getMap(); } //判断用户类型if ("1".equals(type)) { //管理员验证登录User user = userService.login(userName, MD5Utils.getMD5(password)); //对密码进行加密处理，因为数据库中存储的是加密后的密码if (user != null) {session.setAttribute("user", user); session.setAttribute("type", 1); return MapControl.getInstance().success().add("data", user).getMap(); } else {return MapControl.getInstance().error("用户名或密码错误").getMap(); }}if ("2".equals(type)) { //老师验证登录Teacher teacher = teacherService.login(userName, MD5Utils.getMD5(password)); if (teacher != null) {session.setAttribute("user", teacher); session.setAttribute("type", "2"); return MapControl.getInstance().success().add("data", teacher).getMap(); } else {return MapControl.getInstance().error("用户名或密码错误").getMap(); }}if ("3".equals(type)) { //学生验证登录Student student = studentService.login(userName, MD5Utils.getMD5(password)); if (student != null) {session.setAttribute("user", student); session.setAttribute("type", "3"); return MapControl.getInstance().success().add("data", student).getMap(); } else {return MapControl.getInstance().error("用户名或密码错误").getMap(); }}return MapControl.getInstance().getMap(); } }
