spring+mybatis+sharding-jdbc
由于公司业务的拓展，单表数据已经超过几千万行，通过数据库的优化已经不能满足速度的要求。分库分表提到了日程上，必须解决。
恰好看到当当开源了其Sharding-JDBC组件，摘抄一段介绍：
https://github.com/dangdangdotcom/sharding-jdbc
Sharding-JDBC直接封装JDBC API，可以理解为增强版的JDBC驱动，旧代码迁移成本几乎为零：
- 可适用于任何基于
java的ORM框架，如：JPA,Hibernate,Mybatis,Spring JDBC Template或直接使用JDBC。 - 可基于任何第三方的数据库连接池，如：
DBCP,C3P0,BoneCP,Druid等。 - 理论上可支持任意实现
JDBC规范的数据库。虽然目前仅支持MySQL，但已有支持Oracle，SQLServer，DB2等数据库的计划。
Sharding-JDBC定位为轻量级java框架，使用客户端直连数据库，以jar包形式提供服务，未使用中间层，无需额外部署，无其他依赖，DBA也无需改变原有的运维方式。SQL解析使用Druid解析器，是目前性能最高的SQL解析器。
Sharding-JDBC功能灵活且全面：
- 分片策略灵活，可支持
=，BETWEEN，IN等多维度分片，也可支持多分片键共用。 SQL解析功能完善，支持聚合，分组，排序，Limit，OR等查询，并且支持Binding Table以及笛卡尔积的表查询。- 支持柔性事务(目前仅最大努力送达型)。
- 支持读写分离。
Sharding-JDBC配置多样：
- 可支持YAML和Spring命名空间配置
- 灵活多样的
