In the development and testing environment, it is often necessary to bypass the registry and test only designated service providers. In this case, point-to-point direct connection may be required, and the service provider will ignore the list of provider registration providers. The interface A configure Point-to-point, does not affect the B interface to obtain a list from the registry.

<dubbo: reference>, for example:
Then add the configuration in the mapping file
xxx.properties, where key is the service name and value is the service provider URL:
NOTE To avoid complicating the online environment, do not use this feature online and should only be used during the testing phase
