After we have completed the implementation of the service content, we will continue to application.properties do some configuration work, as follows:

By using spring.application.name properties, we can specify that the name of the microservices will follow

Micro-Service Authorization verification
To run a license plate, buy a house and other life, in the harmonious big China and foreign countries, all need a variety of certificates. depend on each other.
Similar authorization certifications should be provided in the MicroServices world. This is a safe line of defense.
