Hi~，Brother Liang. My project also uses open-tracing for jdbc, it will proxy
the **getConnection()** method of **javax.sql.DataSource**, and spring 2.x uses
cglib proxy by default, but ShardingSphereDataSource is a final class. So, if
the **ShardingSphereDataSource** is proxied, this exception will occur. The
similar code like this:
```
@Aspect
public class JdbcAspect {
@Around("execution(java.sql.Connection *.getConnection(..)) &&
target(javax.sql.DataSource)")
public Object getConnection(final ProceedingJoinPoint pjp) throws
Throwable {
return new TracingConnection(conn);
}
}
```
