Today, I will talk to you about the use of the Telnet command in Dubbo. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

After the Dubbo service is released, we can use the telent command to debug and manage

Starting with version 2.0.5, dubbo began to support service governance through telnet commands.

I. connecting services

Test whether the Dubbo service under the corresponding IP and port is connected

> telnet ip port (note that there is no colon between ip and port)

If the connection is normal, you will see "Escape character is'^]'."

Enter to enter Dubbo command mode at this time.

Second, view the list of services

Display a list of services

Dubbo > ls

Display a list of service details

Dubbo > ls-l

Display a list of methods for the service

Dubbo > ls XXXService

Display a list of method details for the service

Dubbo > ls-l XXXService

Display a list of service ports

Dubbo > ps

Display a list of service addresses

Dubbo > ps-l

Display connection information on the port

Dubbo > ps 20880

Display connection details on the port

Dubbo > ps-l 20880

Third, invoke the service interface

The method of invoking the service

Dubbo > invoke XXXService.XXXMethod ({"prop": "value"})

The method that invokes the service (automatically finds the service that contains this method)

Dubbo > invoke XXXMethod ({"prop": "value"})

4. Check the service status

Dubbo > count XXXService

Change the default service. When the default service is set, all commands that need to enter the service name as a parameter can be saved.

Dubbo > cd XXXService

Dubbo > cd /

Show the current default service

Dubbo > pwd

VI. Other orders
