   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);
        }
   
   }
   ```
