申请key

登录高德，注册，添加应用，创建key

官网api：

https://lbs.amap.com/api/webservice/guide/api/weatherinfo

调用步骤: 第一步，申请”web服务 API”密钥（Key）；第二步，拼接HTTP请求URL，第一步申请的Key需作为必填参数一同发送；第三步，接收HTTP请求返回的数据（JSON或XML格式），解析数据。如无特殊声明，接口的输入参数和输出数据编码全部统一为UTF-8。

最主要的也是获取到key

The config for HttpClient

http.maxTotal=300
http.defaultMaxPerRoute=50
http.connectTimeout=1000
http.connectionRequestTimeout=500
http.socketTimeout=5000
http.staleConnectionCheckEnabled=true

gaode.key = 申请的key</pre>

这里获取当前时间的天气情况与未来天气情况返回数据不一样，所在写了2个方法，参数只有一个，城市编码.

1.获取当前天气 http://localhost:2080/weather/getCurrent?adcode=140200

2.获取未来天气 http://localhost:2080/weather/getFuture?adcode=140200
