定义相关的Redis Key

    /*** 单日UV*/public static String getUVKey(String date) {return PREFIX_UV+SPLIT+date;}/*** 记录区间UV* @param startData 开始日期* @param endDate 结束日期* @return*/public static String getUVkey(String startData,String endDate){return PREFIX_UV+SPLIT+startData+SPLIT+endDate;}/*** 单日活跃用户* @param date* @return*/public static String getDAUkey(String date){return PREFIX_DAU+SPLIT+date;}/*** 区间活跃用户* @param startDate 开始日期* @param endDate 结束日期* @return*/public static String getDAUKey(String startDate,String endDate){return PREFIX_DAU+SPLIT+startDate+SPLIT+endDate;}

定义DataService

}

定义拦截器

@Component
public class DataInterceptor implements HandlerInterceptor {@Autowiredprivate DataService dataService;@Autowiredprivate HostHolder hostHolder;//在请求之初统计数据@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response,Object handler) throws Exception{//统计UVString ip= request.getRemoteHost();dataService.recordUV(ip);//统计DAUUser user = hostHolder.getUser();if(user!=null){dataService.recordDAU(user.getId());}return true;}
}

定义Controller

@Controller
public class DataController {@Autowiredprivate DataService dataService;/*** 统计页面的函数* @return*/@RequestMapping(path = "/data",method = {RequestMethod.GET,RequestMethod.POST})public String getDataPage(){return "/site/admin/data";}/*** 统计网站UV* @param start* @param end* @param model* @return*/@RequestMapping(path = "/data/uv",method = RequestMethod.POST)public String getUV(@DateTimeFormat(pattern = "yyyy-MM-dd") Date start , @DateTimeFormat(pattern = "yyyy-MM-dd") Date end, Model model){long uv =dataService.calculateUV(start,end);model.addAttribute("uvResult",uv);model.addAttribute("uvStartDate",start);model.addAttribute("uvEndDate",end);//将处理结果发给/data进行另一半的处理return "forward:/data";
//        return "/site/admin/data";}@RequestMapping(path = "/data/dau",method = RequestMethod.POST)public String getDAU(@DateTimeFormat(pattern = "yyyy-MM-dd") Date start , @DateTimeFormat(pattern = "yyyy-MM-dd") Date end, Model model){long dau =dataService.calculateDAU(start,end);model.addAttribute("dauResult",dau);model.addAttribute("dauStartDate",start);model.addAttribute("dauEndDate",end);//将处理结果发给/data进行另一半的处理return "forward:/data";
//        return "/site/admin/data";}
}

添加权限
