   ```
   **application.yml** is  as follows： 
   ```
   configuration:
     selector: ${SW_CONFIGURATION:consul}
     consul:
       # Consul host and ports, separated by comma, e.g. 1.2.3.4:8500,2.3.4.5:8500
       hostAndPorts: ${SW_CONFIG_CONSUL_HOST_AND_PORTS:192.168.126.143:8500}
       # Sync period in seconds. Defaults to 60 seconds.
       period: ${SW_CONFIG_CONSUL_PERIOD:60}
       # Consul aclToken
       aclToken: ${SW_CONFIG_CONSUL_ACL_TOKEN:""}
   ```
   My consul server do not need Consul aclToken.
