复制代码- AddressServerGeneratorManager of generateProductName method for name is empty or is nacos returns nacos.as.default, otherwise nacos.as. Prefix and name
- generateNacosServiceName returns DEFAULT_GROUP @@ plus rawServiceName, default rawServiceName is not included in the DEFAULT_GROUP
- generateInstancesByIps method to traverse ipArray, one by one to create instance, pay attention to here is set to false ephemeral
