java------4.根据经纬度排序，并计算距离。。。。。。。。根据地址计算出经纬度

 1 String sql = "select xm.*,xs.*,xs.id as shopId,sqrt (   (  (( " + customerLongitude
 2                     + "-xs.longitude)*PI()*12656*COS(((" + customerLatitude
 3                     + "+xs.latitude)/2)*PI()/180)/180)" + "*" + "((  "
 4                     + customerLongitude + "-xs.longitude)*PI()*12656*COS((("
 5                     + customerLatitude + "+xs.latitude)/2)*PI()/180)/180) " + ")"
 6                     + "+(" + "  (( " + customerLatitude
 7                     + "-xs.latitude)*PI()*12656/180) " + "*" + "((" + customerLatitude
 8                     + "-xs.latitude)*PI()*12656/180)" + " )" + " ) as juli ";

11 double LonB = Double.parseDouble(m.get("longitude").toString());
12             double LatB = Double.parseDouble(m.get("latitude").toString());
13             double distance = Math.floor(XiNaiInterfaceUtils.getDistance(customerLongitude,customerLatitude, LonB, LatB) / 1000*10)/10;

计算经纬度 需要 commons-lang3-3.1.jar
