The following shows the other configurations of the starter of Nacos Discovery:

Configuration	Key	Default Value	Description
Server address	`spring.cloud.nacos.discovery.server-addr`		IP and port of the Nacos Server listener
Service name	`spring.cloud.nacos.discovery.service`	`${spring.application.name}`	Name the current service
Weight	`spring.cloud.nacos.discovery.weight`	`1`	Value range: 1 to 100. The bigger the value, the greater the weight
Network card name	`spring.cloud.nacos.discovery.network-interface`		If the IP address is not specified, the registered IP address is the IP address of the network card. If this is not specified either, the IP address of the first network card will be used by default.
Registered IP address	`spring.cloud.nacos.discovery.ip`		Highest priority
Registered port	`spring.cloud.nacos.discovery.port`	`-1`	Will be detected automatically by default. Do not need to be configured.
Namespace	`spring.cloud.nacos.discovery.namespace`		A typical scenario is to isolate the service registration for different environment, such as resource (configurations, services etc.) isolation between testing and production environment
AccessKey	`spring.cloud.nacos.discovery.access-key`		Alibaba Cloud account accesskey
SecretKey	`spring.cloud.nacos.discovery.secret-key`		Alibaba Cloud account secretkey
Metadata	`spring.cloud.nacos.discovery.metadata`		You can define some of the metadata for your services in the Map format
Log file name	`spring.cloud.nacos.discovery.log-name`
Cluster Name	`spring.cloud.nacos.discovery.cluster-name`	`DEFAULT`	Cluster name of Nacos
Endpoint	`spring.cloud.nacos.discovery.endpoint`		The domain name of a certain service in a specific region. You can retrieve the server address dynamically with this domain name
Integrate Ribbon or not	`ribbon.nacos.enabled`	`true`	Set to true in most cases
Enable Nacos Watch	`spring.cloud.nacos.discovery.watch.enabled`	`true`	set to false to close watch
