java计算二个经纬度间的距离(百度坐标)

1：背景

工作中遇到计算二个地点之间的距离，根据百度经纬度进行计算。

2：maven 依赖

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

3：代码实现

        GlobalCoordinates target = new GlobalCoordinates(31.235124000000, 121.530746000000);

    }
