如何使用Google地图java客户端库获取距离

import com.google.maps.DistanceMatrixApi;
import com.google.maps.DistanceMatrixApiRequest;
import com.google.maps.GeoApiContext;
import com.google.maps.model.Distance;
import com.google.maps.model.DistanceMatrix;
import com.google.maps.model.DistanceMatrixElementStatus;
import com.google.maps.model.LatLng;

public class GoogleMapsDistanceExample {
    public static void main(String[] args) {
        // 初始化地图服务对象
        String apiKey = "YOUR_API_KEY";
        GeoApiContext context = new GeoApiContext.Builder().apiKey(apiKey).build();

        // 发起距离请求
        LatLng origin = new LatLng(37.7749, -122.4194); // 起始点坐标
        LatLng destination = new LatLng(34.0522, -118.2437); // 目标点坐标
        DistanceMatrixApiRequest request = DistanceMatrixApi.newRequest(context)
                .origins(origin)
                .destinations(destination);
        try {
            // 处理距离响应
            DistanceMatrix matrix = request.await();
            if (matrix.rows[0].elements[0].status == DistanceMatrixElementStatus.OK) {
                Distance distance = matrix.rows[0].elements[0].distance;
                System.out.println("距离：" + distance.humanReadable);
            } else {
                System.out.println("无法获取距离信息");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
