   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 DataSource 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);
   	}
   
   }
   ```
