班级信息控制器:
@Controller @RequestMapping("classes") public class ClassesController {
@Autowired private ClassesService classesService; @Autowired private
InstituteService instituteService; @PostMapping("list") @ResponseBody public
PageResultVo loadClasses(ClassesConditionVo classesConditionVo, Integer limit,
Integer offset) { PageHelper.startPage(PageUtil.getPageNo(limit,
offset),limit); List<Classes> classesList =
classesService.findByCondition(classesConditionVo); PageInfo<Classes> pages =
new PageInfo<>(classesList); return ResultUtil.table(classesList,
pages.getTotal(), pages); } /** * 新增班级 * @param classes * @return */
@PostMapping("/add") @ResponseBody public ResponseVo add(Classes classes) {
User user = (User)SecurityUtils.getSubject().getPrincipal();
classes.setAuthor(user.getNickname()); Date date = new Date();
classes.setCreateTime(date); classes.setUpdateTime(date);
classes.setStatus(CoreConst.STATUS_INVALID); int i =
classesService.insert(classes); if(i > 0) { return
ResultUtil.success("新增班级信息成功"); }else { return ResultUtil.error("新增班级信息失败"); }
} /** * 更新班级信息 * @param model * @param id * @return */ @GetMapping("/edit")
public String edit(Model model,Integer id) { Classes classes =
classesService.selectById(id); List<Institute> institutes =
instituteService.selectAll(); model.addAttribute("institutes",institutes);
model.addAttribute("classes", classes); return "classes/detail"; }
@PostMapping("/edit") @ResponseBody public ResponseVo edit(Classes classes) {
int i = classesService.updateNotNull(classes); if(i > 0) { return
ResultUtil.success("更新班级信息成功"); }else { return ResultUtil.error("更新班级信息失败"); }
} /** * 删除班级信息 * @param id * @return */ @PostMapping("/delete") @ResponseBody
public ResponseVo delete(Integer id) { //验证班级下是否有学生 int i =
classesService.validateByClassIds(new Integer[] {id}); if(i > 0) { return
ResultUtil.error("无法删除,该班级中还有学生"); }else { int j =
classesService.deleteBatch(new Integer[] {id}); if(j > 0) { return
ResultUtil.success("删除班级信息成功"); }else { return ResultUtil.error("删除班级信息 失败"); }
} } /** * 批量删除 * @param ids * @return */ @PostMapping("/batch/delete")
@ResponseBody public ResponseVo deleteBatch(@RequestParam("ids[]")
Integer[]ids) { //验证该班级中是否有学生 int i = classesService.validateByClassIds(ids);
if(i > 0) { return ResultUtil.error("无法批量删除,该班级中还有学生"); }else { int j =
classesService.deleteBatch(ids); if(j > 0) { return
ResultUtil.success("批量删除班级信息成功"); }else { return
ResultUtil.error("批量删除班级信息失败"); } } } }

评论控制层:
@RestController @RequestMapping("comment") public class CommentController {
@Autowired private CommentService commentService; @PostMapping("list") public
PageResultVo loadNotify(CommentConditionVo comment, Integer limit, Integer
offset){ PageHelper.startPage(PageUtil.getPageNo(limit, offset),limit);
List<Comment> comments = commentService.selectComments(comment);
PageInfo<Comment> pages = new PageInfo<>(comments); return
ResultUtil.table(comments,pages.getTotal(),pages); } @PostMapping("/reply")
public ResponseVo edit(Comment comment){ completeComment(comment); int i =
commentService.insertSelective(comment); if(i>0){ return
ResultUtil.success("回复评论成功"); }else{ return ResultUtil.error("回复评论失败"); } }
@PostMapping("/delete") public ResponseVo delete(Integer id){
Integer[]ids={id}; int i = commentService.deleteBatch(ids); if(i>0){ return
ResultUtil.success("删除评论成功"); }else{ return ResultUtil.error("删除评论失败"); } }
@PostMapping("/batch/delete") public ResponseVo
deleteBatch(@RequestParam("ids[]") Integer[]ids){ int i =
commentService.deleteBatch(ids); if(i>0){ return ResultUtil.success("删除评论成功");
}else{ return ResultUtil.error("删除评论失败"); } } @PostMapping("/audit") public
ResponseVo audit(Comment bizComment, String replyContent){ try {
commentService.updateNotNull(bizComment);
if(StringUtils.isNotBlank(replyContent)){ Comment replyComment = new Comment();
replyComment.setPid(bizComment.getId());
replyComment.setSid(bizComment.getSid());
replyComment.setContent(replyContent); completeComment(replyComment);
commentService.insertSelective(replyComment); } return
ResultUtil.success("审核成功"); } catch (Exception e) { return
ResultUtil.success("审核失败"); } } private void completeComment(Comment comment){
HttpServletRequest request = ((ServletRequestAttributes)
RequestContextHolder.getRequestAttributes()).getRequest(); User user =
(User)SecurityUtils.getSubject().getPrincipal();
comment.setUserId(user.getUserId()); comment.setNickname(user.getNickname());
comment.setEmail(user.getEmail()); comment.setAvatar(user.getImg());
comment.setIp(IpUtil.getIpAddr(request));
comment.setStatus(CoreConst.STATUS_VALID); } }

用户信息控制层:
@Controller @RequestMapping("/online/user") public class OnlineUserController
{ @Autowired private UserService userService; // 在线用户列表 @PostMapping("/list")
@ResponseBody public PageResultVo onlineUsers(UserOnlineVo user, Integer limit,
Integer offset){ List<UserOnlineVo> userList =
userService.selectOnlineUsers(user); PageInfo<UserOnlineVo> pages = new
PageInfo<>(userList); int endIndex = (offset+limit) > userList.size() ?
userList.size() : (offset+limit); return
ResultUtil.table(userList.subList(offset,endIndex),(long)userList.size(),pages);
} // 强制踢出用户 @PostMapping("/kickout") @ResponseBody public ResponseVo
kickout(String sessionId,String username) { try {
if(SecurityUtils.getSubject().getSession().getId().equals(sessionId)){ return
ResultUtil.error("不能踢出自己"); } userService.kickout(sessionId,username); return
ResultUtil.success("踢出用户成功"); } catch (Exception e) { return
ResultUtil.error("踢出用户失败"); } } // 批量强制踢出用户 @PostMapping("/batch/kickout")
@ResponseBody public ResponseVo kickout(@RequestBody List<UserSessionVo>
sessions) { try { //要踢出的用户中是否有自己 boolean hasOwn=false; Serializable sessionId =
SecurityUtils.getSubject().getSession().getId(); for (UserSessionVo sessionVo :
sessions) { if(sessionVo.getSessionId().equals(sessionId)){ hasOwn=true; }else{
userService.kickout(sessionVo.getSessionId(),sessionVo.getUsername()); } }
if(hasOwn){ return ResultUtil.success("不能踢出自己"); } return
ResultUtil.success("踢出用户成功"); } catch (Exception e) { return
ResultUtil.error("踢出用户失败"); } } }
