shardingsphere使用
如果使用了druid，依赖必须使用druid，而不能是 druid-spring-boot-starter
<!-- druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.22</version>
</dependency>
<!-- shardingsphere -->
<dependency>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>sharding-jdbc-spring-boot-starter</artifactId>
<version>4.1.0</version>
</dependency>
