用户管理操作控制层:
/** * 用户管理操作 */ @Controller @RequestMapping("/user") public class UserController { @Autowired private 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") @ResponseBody public Mapadd(@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}") @ResponseBody public 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") @ResponseBody public 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") @ResponseBody public 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") @ResponseBody public 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"; } }

公告管理控制器:
/** * 公告管理控制器 */ @Controller @RequestMapping("/notice") public class NoticeController { @Autowired private 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") @ResponseBody public Mapadd(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}") @ResponseBody public 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") @ResponseBody public 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") @ResponseBody public 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") @ResponseBody public 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:
@Controller public class LoginController { @Autowired private UserService userService; @Autowired private TeacherService teacherService; @Autowired private StudentService studentService; //跳转登录页面 @GetMapping("/login") public String login() { return "login"; } //登录操作 @PostMapping("/login") @ResponseBody public Maplogin(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(); } }
