情况概述：

　　今天对天气查询进行处理，对气温进行追踪，并展示。

代码如下：

<%@page import="com.zlc.entity.WeatherBean"%>
<%@page import="com.zlc.dao.IWeatherDao"%>
<%@page import="com.zlc.service.IWeatherService"%>
<%@page import="com.zlc.dao.impl.WeatherDaoImpl"%>
<%@page import="com.zlc.service.impl.WeatherServiceImpl"%>
<%@page import="java.util.ArrayList"%>
<%@page import="java.util.List"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
    IWeatherService service = new WeatherServiceImpl();
    IWeatherDao dao = new WeatherDaoImpl();
    List<WeatherBean> weathers = new ArrayList<WeatherBean>();
    weathers = (ArrayList<WeatherBean>) request.getAttribute("weathers");
    //weathers = service.queryAllWeathersByCityDate("北京", 20160606);
