   ### Which version of ShardingSphere did you use?
   3.1.0
   ### Which project did you use? Sharding-JDBC or Sharding-Proxy?
   Sharding-JDBC
   ### Expected behavior
   no sharding tables  use default-data-source
   ### Actual behavior
   no sharding tables's select actions did not use default-data-source(ds2) but use ds0.
   But update,insert and delete actions use ds2
   ### Reason analyze (If you can)
   
   ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
   config:
   ```yaml
   sharding:
     jdbc:
       datasource:
         names: ds0,ds1,ds2
         ds0:
           type: com.alibaba.druid.pool.DruidDataSource
           driver-class-name: com.mysql.jdbc.Driver
           url: jdbc:mysql://10.82.27.177:3306/ds0
           username: root
           password: 123456
         ds1:
           type: com.alibaba.druid.pool.DruidDataSource
           driver-class-name: com.mysql.jdbc.Driver
           url: jdbc:mysql://10.82.27.177:3306/ds1
           username: root
           password: 123456
         ds2:
           type: com.alibaba.druid.pool.DruidDataSource
           driver-class-name: com.mysql.jdbc.Driver

               statement.execute("insert into user(name,age) value('2012-12-12 12:12:12',1212)");
