Configuration is as follows：
`ShardingRuleConfiguration ruleConfiguration = new
ShardingRuleConfiguration();
ruleConfiguration.getBindingTableGroups().add("t_order,t_order_item");
ShardingTableRuleConfiguration tableRuleConfiguration = new
ShardingTableRuleConfiguration("t_user","ds$->{0..1}.t_user_$->{0..3}");
tableRuleConfiguration.setDatabaseShardingStrategy(new
StandardShardingStrategyConfiguration("user_id","db_mode_algorithm"));
tableRuleConfiguration.setTableShardingStrategy(new
StandardShardingStrategyConfiguration("user_id","tab_mode_algorithm"));
ShardingTableRuleConfiguration orderTableRuleConfiguration = new
ShardingTableRuleConfiguration("t_order","ds$->{0..1}.t_order_$->{0..3}");
