Java 通过地址获取经纬度 - 高德地图

一、添加依赖

            <dependency>

                <groupId>org.hibernate</groupId>

                <artifactId>hibernate-validator</artifactId>

                <version>6.0</version>

            </dependency>

二、请求工具类

import com.github.kevinsawicki.http.HttpRequest;

/**

 * 请求工具类

 */

public class RequestUtils {

    private static final String DEFAULT_CHARSET = "utf-8";

    private static final int CONNECT_TIMEOUT_IN_MIS_SECOND = 10000;

    private static final int READ_TIMEOUT_IN_MIS_SECOND = 30000;

    public static RequestResult getJsonText(String url, String charset) {

        if (charset == null) charset = DEFAULT_CHARSET;

        HttpRequest request = HttpRequest.get(url).connectTimeout(CONNECT_TIMEOUT_IN_MIS_SECOND).readTimeout(READ_TIMEOUT_IN_MIS_SECOND);

        String body = request.body(charset);

        int code = request.code();

        request.disconnect();

        return new RequestResult(code, body);

    }

}

三、返回接收类

import lombok.AllArgsConstructor;

import lombok.Getter;

import lombok.Setter;

/**

 *  高德地图返回工具类

 */

@Getter

@Setter

@AllArgsConstructor

public class RequestResult {

    /** 状态码 */

    private int code;

    /** 返回body */

    private  String body;

}

四、高德地图工具类

import java.net.URLEncoder;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

/**

 * 获取高德地图经纬度

 *

 * @author lixin.saho

 */

public class MapUtils {

    private static String API = "http://restapi.amap.com/v3/geocode/geo?key=<key>&s=rsv3&address=<address>";

    private static String KEY = "key";

    private static Pattern pattern = Pattern.compile("\"location\":\"(\\d+\\.\\d+),(\\d+\\.\\d+)\"");

    static {

        init();

    }

    private static void init() {

//        System.out.println("高德地图工具类初始化");

//        System.out.println("api: {}"+API);

//        System.out.println("key: {}"+KEY);

        API = API.replaceAll("<key>", KEY);

    }

    private static double[] getLatAndLonByAddress(String address) {

        try {

            String requestUrl = API.replaceAll("<address>", URLEncoder.encode(address, "UTF-8"));

            RequestResult requestResult = RequestUtils.getJsonText(requestUrl, null);

            if (200 != requestResult.getCode()) {

                return null;

            }

            requestUrl = requestResult.getBody();

            if (requestUrl != null) {

                Matcher matcher = pattern.matcher(requestUrl);

                if (matcher.find() && matcher.groupCount() == 2) {

                    double[] gps = new double[2];

                    gps[0] = Double.valueOf(matcher.group(1));

                    gps[1] = Double.valueOf(matcher.group(2));

                    return gps;

                }

            }

        } catch (Exception e) {

            e.printStackTrace();

        }

        return null;

    }

    public static void main(String[] args) {

        double[] aaa = MapUtils.getLatAndLonByAddress("广东省深圳市福田区天安数码城创业科技大厦一期");

        for (double cccc : aaa) {

            System.out.println(cccc);

        }

        System.out.println(MapUtils.getLatAndLonByAddress("广东省深圳市福田区天安数码城创业科技大厦一期"));

    }

五、高德地图的秘钥，及高德地图工具类里的key需要自己申请
