根据百度API获取天气详细代码

需要自行申请百度AK。

获取天气方法：

/**
 * 百度车联网 天气接口<br>
 * API网址：http://developer.baidu.com/map/carapi-7.htm<br>
 * 5000次/天免费,多于无数据返回

WeatherBean实体类，用于封装数据：

package cn.com.test.utils.weather;

import java.util.Date;
import java.util.List;

public abstract class WeatherWorker {
public abstract List<WeatherBean> getWeather(final String... args) throws Exception;
	
	public class WeatherBean {
		public String cityName;
		public String cityCode;
		public Date dataTime;
		public Date date;
		public String weather;
		public Integer temprature_1;
		public Integer temprature_2;
		public String wind;
		public String wind_way;
		public String wind_power;
		public String img_1;
		public String img_2;
		public String temprature_str;
		
		@Override
		public String toString() {
			return "WeatherBean [cityName=" + cityName + ", cityCode="
					+ cityCode + ", dataTime=" + dataTime + ", date=" + date
					+ ", weather=" + weather + ", temprature_1=" + temprature_1
					+ ", temprature_2=" + temprature_2 + ", wind=" + wind
					+ ", wind_way=" + wind_way + ", wind_power=" + wind_power
