Lookup order

Default host IP lookup order:

  • Get local address via LocalHost.getLocalHost().
  • If it is 127. * loopback address, then scan the network for host IP

Registered address if it is not correct, such as the need to register public address, you can do this:

  1. edit /etc/hosts : add machinename and public ip, such as:

     test1 205.182.23.201
    
  2. in dubbo.xml add host address configuration:

     <dubbo:protocol host="205.182.23.201">
    
  3. or config that in dubbo.properties:

    dubbo.protocol.host=205.182.23.201
