哦,, 日志打印的sql语句是:

SELECT * FROM RTS_SDO_SPATIAL where SDO_WITHIN_DISTANCE(RTS_SDO_SPATIAL.SDODATA,SDO_GEOMETRY(2001, 4490, MDSYS.SDO_POINT_TYPE(114.374296952994, 22.7277813986333, null), null, null),'distance=1000.0')='TRUE'

String sqlStr = "SELECT * FROM RTS_SDO_SPATIAL where SDO_WITHIN_DISTANCE(RTS_SDO_SPATIAL.SDODATA,SDO_GEOMETRY(2001, 4490, MDSYS.SDO_POINT_TYPE(@lat, @lon, null), null, null),'distance=@radius')='TRUE'";
		Sql sql = Sqls.create(sqlStr);
		sql.params().set("lat", point.getX()).set("lon", point.getY()).set("radius", radius);
		Entity<Rts_Sdo> entity = dao().getEntity(Rts_Sdo.class);
		sql.setEntity(entity);
		sql.setCallback(Sqls.callback.entities());
        Sql execute = dao().execute(sql);
		List<Rts_Sdo> rtsSdo = sql.getList(Rts_Sdo.class);
		return rtsSdo;

我建的是空间索引 和 一般的b-tree不一样

那我把参数直接拼到sql里面试试

行 我试试

好了 是我设置值时错了 现在可以了,谢谢大佬!
