Logical table names in sharding configuration can be case sensitive

[wangdengyang]

目前sql查询的表名必须跟逻辑表填写的大小写一致，能否改为忽略大小写呢
配置：
<sharding:sharding-rule data-source-names="demo_ds">
sharding:table-rules
<sharding:table-rule logic-table="T_ORDER" actual-data-nodes="demo_ds.t_order_${0..2}" table-strategy-ref="orderTableShardingStrategy" generate-key-column="order_id" />
<sharding:table-rule logic-table="T_ORDER_ITEM" actual-data-nodes="demo_ds.t_order_item_${0..2}" table-strategy-ref="orderItemTableShardingStrategy" generate-key-column="order_item_id" />
</sharding:table-rules>
sharding:binding-table-rules
<sharding:binding-table-rule logic-tables="t_order, t_order_item"/>
</sharding:binding-table-rules>

SQL语句:
SELECT
i.*
FROM
t_order o, t_order_item i
WHERE
o.order_id = i.order_id
此时sql语句中表名大小写跟逻辑表中不一致，无法查询到结果
日志打印：
[INFO ] 2017-12-15 10:30:03,733 --main-- [Sharding-JDBC-SQL] Actual SQL: demo_ds ::: SELECT
i.*
FROM
t_order o, t_order_item_0 i
WHERE
o.order_id = i.order_id
[INFO ] 2017-12-15 10:30:03,733 --main-- [Sharding-JDBC-SQL] Actual SQL: demo_ds ::: SELECT
i.*
FROM
t_order o, t_order_item_1 i
WHERE
o.order_id = i.order_id
[INFO ] 2017-12-15 10:30:03,733 --main-- [Sharding-JDBC-SQL] Actual SQL: demo_ds ::: SELECT
i.*
FROM
t_order o, t_order_item_2 i
WHERE
o.order_id = i.order_id
[]

我把逻辑表的大小写改为跟查询sql的一致，就能正常查到结果
