环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
项目技术： Jdbc+ Servlert + Jsp + css + JavaScript + JQuery + Ajax + Fileupload等等。
登录拦截器代码：
@Componentpublic class LoginInterceptor implements HandlerInterceptor{ private Logger log = LoggerFactory.getLogger(LoginInterceptor.class);@Autowiredprivate SiteConfig siteConfig;@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler){String requestURI = request.getRequestURI();HttpSession session = request.getSession();session.setAttribute(SessionConstant.SESSION_USER_AUTH_KEY, AppConfig.ORDER_AUTH); Object attribute = session.getAttribute(SessionConstant.SESSION_USER_LOGIN_KEY);if(attribute == null){log.info("用户还未登录或者session失效,重定向到登录页面,当前URL=" + requestURI);//首先判断是否是ajax请求if(StringUtil.isAjax(request)){//表示是ajax请求try {response.setCharacterEncoding("UTF-8");response.getWriter().write(JSON.toJSONString(CodeMsg.USER_SESSION_EXPIRED));} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return false;}//说明是普通的请求，可直接重定向到登录页面//用户还未登录或者session失效,重定向到登录页面try {response.sendRedirect("/system/login");} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}return false;}log.info("该请求符合登录要求，放行" + requestURI);if(!StringUtil.isAjax(request)){//若不是ajax请求，则将菜单信息放入页面模板变量User user = (User)attribute;List<Menu> authorities = user.getRole().getAuthorities();request.setAttribute("userTopMenus", MenuUtil.getTopMenus(authorities));List<Menu> secondMenus = MenuUtil.getSecondMenus(user.getRole().getAuthorities());request.setAttribute("userSecondMenus", secondMenus);request.setAttribute("userThirdMenus", MenuUtil.getChildren(MenuUtil.getMenuIdByUrl(requestURI,secondMenus),authorities));request.setAttribute("siteName", siteConfig.getSiteName());request.setAttribute("siteUrl", siteConfig.getSiteUrl());}return true;}}医院预约挂号系统后台管理页面代码：
