// 根据距离由近及远排序
wrapper.orderByDistanceAsc(boolean condition, R column, Geopoint...geoPoints);
// 根据距离由远及近排序
wrapper.orderByDistanceDesc(boolean condition, R column, Geopoint...geoPoints);
使用示例
@Test
public void testOrderByDistanceAsc() {
// 测试给定中心点, 查询出中心点168.8km范围内的数据,并按照距中心点距离由近及远排序
LambdaEsQueryWrapper<Document> wrapper = new LambdaEsQueryWrapper<>();
GeoPoint centerPoint = new GeoPoint(41.0, 116.0);
wrapper.match(Document::getCreator, "老汉")
.geoDistance(Document::getLocation, 168.8, centerPoint)
.orderByDistanceAsc(Document::getLocation, centerPoint);
List<Document> documents = documentMapper.selectList(wrapper);
System.out.println(documents);
}
