ShardingSphere 涵盖了很多功能，例如，分库分片、读写分离、数据脱敏等。这些功能用户可以单独进行使用，也可以配合一起使用，下面是基于 Spring 命名空间 配置示例。
<!-- 分片配置 -->
<sharding:standard-strategy id="databaseStrategy" sharding-column="user_id" algorithm-ref="inlineStrategyShardingAlgorithm" />
<sharding:sharding-algorithm id="inlineStrategyShardingAlgorithm" type="INLINE">
<props>
<prop key="algorithm-expression">replica_ds_${user_id % 2}</prop>
</props>
</sharding:sharding-algorithm>
<sharding:key-generate-algorithm id="snowflakeAlgorithm" type="SNOWFLAKE">
</sharding:key-generate-algorithm>
<sharding:key-generate-strategy id="orderKeyGenerator" column="order_id" algorithm-ref="snowflakeAlgorithm" />
<sharding:rule id="shardingRule">
<sharding:table-rules>
<sharding:table-rule logic-table="t_order" database-strategy-ref="databaseStrategy" key-generate-strategy-ref="orderKeyGenerator" />
</sharding:table-rules>
</sharding:rule>
<!-- 动态读写分离配置 -->
<readwrite-splitting:rule id="readWriteSplittingRule">
<readwrite-splitting:data-source-rule id="replica_ds_0">
<readwrite-splitting:dynamic-strategy id="dynamicStrategy" auto-aware-data-source-name="readwrite_ds_0" />

<readwrite-splitting:data-source-rule id="replica_ds_1">
<readwrite-splitting:dynamic-strategy id="dynamicStrategy" auto-aware-data-source-name="readwrite_ds_1" />
</readwrite-splitting:data-source-rule>
</readwrite-splitting:rule>
<!-- 数据库发现配置 -->
