Java计算两个经纬度间的距离最简单的方式

开发中经常会遇到计算两个点（经纬度）之间的距离或者计算最近门店的场景，下面简单实现一下如何计算两个经纬度之间相隔的距离。

1、导入geodesy的maven依赖或者到阿里云maven仓库下载jar包

<dependency>
　　<groupId>org.gavaghan</groupId>
　　<artifactId>geodesy</artifactId>
　　<version>1.1.3</version>
</dependency>

2、实现计算

package com.test.gps;
 
import org.gavaghan.geodesy.Ellipsoid;
import org.gavaghan.geodesy.GeodeticCalculator;
import org.gavaghan.geodesy.GeodeticCurve;
import org.gavaghan.geodesy.GlobalCoordinates;
 
public class CaculateDistanceTest
{
    public static void main(String[] args)
    {
        GlobalCoordinates source = new GlobalCoordinates(29.490295, 106.486654);
        GlobalCoordinates target = new GlobalCoordinates(29.615467, 106.581515);
 
        double meter1 = getDistanceMeter(source, target, Ellipsoid.Sphere);
        double meter2 = getDistanceMeter(source, target, Ellipsoid.WGS84);
 
        System.out.println("Sphere坐标系计算结果："+meter1 + "米");
        System.out.println("WGS84坐标系计算结果："+meter2 + "米");
    }
 
    public static double getDistanceMeter(GlobalCoordinates gpsFrom, GlobalCoordinates gpsTo, Ellipsoid ellipsoid)
    {
        //创建GeodeticCalculator，调用计算方法，传入坐标系、经纬度用于计算距离
        GeodeticCurve geoCurve = new GeodeticCalculator().calculateGeodeticCurve(ellipsoid, gpsFrom, gpsTo);
 
        return geoCurve.getEllipsoidalDistance();
    }
}
