@Lychengit You can try like this.
```
// 配置分库策略
orderTableRuleConfig.setDatabaseShardingStrategy(new
ComplexShardingStrategyConfiguration("user_id,order_id",
"dbShardingAlgorithm"));
// 配置分库算法
Properties dbShardingAlgorithmrProps = new Properties();
dbShardingAlgorithmrProps.setProperty("algorithm-expression",
"ds${(user_id % 2) + (order_id % 3)}");
shardingRuleConfig.getShardingAlgorithms().put("dbShardingAlgorithm", new
ShardingSphereAlgorithmConfiguration("COMPLEX_INLINE",
dbShardingAlgorithmrProps));```
