Can anyone give me some DistSQL example for Class Based Sharding Algorithm ?

[weideguo]

CREATE SHARDING TABLE RULE t_order (
DATANODES("ds_pay.t_order_${2019..2025}"),
TABLE_STRATEGY(TYPE="CLASS_BASED",SHARDING_COLUMN=order_no,SHARDING_ALGORITHM(TYPE(NAME="STANDARD",PROPERTIES("algorithmClassName"="com.sharding.algorithm.DemoAlgorithm"))))
);

Is there any thing wrong on this? When I run and got:

ERROR 30000 (HY000): Unknown exception: SPI-00001: No implementation class load from SPI `org.apache.shardingsphere.sharding.spi.ShardingAlgorithm`.
