评论业务控制器：

/** * 评论控制器 * @author yy * */@RestController@RequestMapping("/comment")public class CommentController {   @Resource  private CommentService commentService;   @Resource  private ArticleService articleService;   @Resource  private ReplyService replyService;   /**   * 分页查询评论   * @param comment   * @param page   * @param pageSize   * @return   */  @RequestMapping("/list")  public Map commentList(Comment comment, @RequestParam(value = "page", required = false) Integer page,                                         @RequestParam(value = "pageSize", required = false) Integer pageSize) {    List commentList = commentService.list(comment, null, null, page - 1, pageSize, null);    Long total = commentService.getCount(comment, null, null, null);    int totalPage = (int) (total % pageSize == 0 ? total / pageSize : total / pageSize + 1);    Map resultMap = new HashMap();    resultMap.put("totalPage", totalPage);    resultMap.put("data", commentList);    return resultMap;  }   /**   * 分页查询评论   * @param page   * @param pageSize   * @return   */  @RequestMapping("/massageList")  public Map massageList(@RequestParam(value = "page", required = false) Integer page,                                         @RequestParam(value = "pageSize", required = false) Integer pageSize) {    List commentList = commentService.massageList(page - 1, pageSize);    Long total = commentService.getCount2();    int totalPage = (int) (total % pageSize == 0 ? total / pageSize : total / pageSize + 1);    Map resultMap = new HashMap();    resultMap.put("totalPage", totalPage);    resultMap.put("data", commentList);    return resultMap;  }   /**   * 添加评论   * @Title: add   * @param comment  评论实体   * @return  参数说明   * @return Map    返回类型   * @throws   */  @RequestMapping("/add")  public Map add(Comment comment, HttpSession session) {    User currentUser = (User) session.getAttribute("user");    Map resultMap = new HashMap();    comment.setCommentDate(new Date());    comment.setUser(currentUser);    commentService.add(comment);    if (comment.getArticle() != null) {      articleService.increaseComment(comment.getArticle().getArticleId());    }    resultMap.put("comment", comment);    resultMap.put("success", true);    return resultMap;  } }

回复业务控制器:

/** * 回复控制器 * @author yy * */@RestController@RequestMapping("/reply")public class ReplyController {   @Resource  private ReplyService replyService;   /**   * 获取回复   * @param reply   * @return   */  @RequestMapping("/list")  public Map replyList(Reply reply) {    List replyList = replyService.list(reply);    Map resultMap = new HashMap();    resultMap.put("data", replyList);    return resultMap;  }   /**   * 添加回复   * @param reply   * @return   */  @RequestMapping("/add")  public Map add(Reply reply, HttpSession session) {    User currentUser = (User) session.getAttribute("user");    Map resultMap = new HashMap();    reply.setReplyDate(new Date());    reply.setUser(currentUser);    replyService.add(reply);    resultMap.put("reply", reply);    resultMap.put("success", true);    return resultMap;  } }

管理员业务控制器:

/** * 管理员控制器 * @author yy * */@RestController@RequestMapping("/admin")public class AdminController {   @Value("${MD5Salt}")  private String salt; // md5加密盐   @Resource  private AdminService adminService;  @Resource  private UserService userService;  @Resource  private ArticleService articleService;  @Resource  private ClassifyService classifyService;   /**   * 后台管理员登录验证   * @param admin   * @param request   * @return   */  @RequestMapping("/login")  public ModelAndView login(Admin admin, HttpServletRequest request) {    ModelAndView mav = new ModelAndView();    HttpSession session = request.getSession();    try {      Admin resultUser = adminService.findByUserNameAndPassword(admin.getUserName(), admin.getPassword());      if (resultUser == null) {        mav.addObject("errorInfo", "用户名或者密码错误!");        mav.setViewName("/login");      } else {        session.setAttribute("adminUser", resultUser);        // 统计用户总数        Long userCount = userService.getCount();        // 统计今天注册        Long userRegCount = userService.getTodayRegistCount(new User(), "1", "1");        // 统计今日登录        Long userLogCount = userService.getCount(new User(), "1", "1");        // 统计笔记总数        Long artCount = articleService.getCount();        // 统计笔记分类        Long classCount = classifyService.getCount();         session.setAttribute("userCount", userCount);        session.setAttribute("userRegCount", userRegCount);        session.setAttribute("userLogCount", userLogCount);        session.setAttribute("artCount", artCount);        session.setAttribute("classCount", classCount);         mav.addObject("success", true);        mav.setViewName("/admin/index");      }    } catch (Exception e) { // 用户名密码错误      e.printStackTrace();      mav.addObject("admin", admin);      mav.addObject("errorInfo", "用户名或者密码错误!");      mav.setViewName("/login");    }    return mav;  }   /**   * 查看个人信息   *    * @return   */  @RequestMapping("viewPerson")  public ModelAndView viewPerson(HttpServletRequest request) {    Admin admin = (Admin) request.getSession().getAttribute("adminUser");    ModelAndView mav = new ModelAndView();    Admin u = adminService.findById(admin.getAdminId());    mav.addObject("user", u);    mav.setViewName("/admin/adminViewPerson");    return mav;  }   /**   * 保存用户信息   *    * @param user   * @return   */  @RequestMapping("/save")  public ModelAndView save(Admin user) {    ModelAndView mav = new ModelAndView();    adminService.save(user);    mav.setViewName("/admin/index");    return mav;  }}
