Distributed series-Dubbo service telnet command

after the Dubbo service is released, we can debug and manage it using the Telnet command.
Dubbo2.0.5 above version of service provides port support Telnet command, below I take a look at windows as an example : 1. Connection Service

Test if the Dubbo service under the corresponding IP and port is connected, the cmd command is as follows

telnet localhost 20880

Under normal circumstances, enter the Telnet window and type enter Enter the Dubbo command mode .

2. View Service List View service

Dubbo>ls

Com.test.DemoService

View interfaces in a service

Dubbo>ls Com.test.DemoService

Querydemopagelist

Insert DemoList

Upload DemoList

Delete DemoList

Ls

3. Invoking the Service interfaceWhen the interface is called, the parameters are passed in JSON format (which is handy:-D), and then the return value and time are printed.

Dubbo>invoke Com.test.DemoService . Query Demopagelist ({"id": "+"}, 1, 2)

{"TotalCount": 1, "data": [{Date ":" 2011-03-23 14:10:32 "," name ":" Zhang San "," keyword ": null}]}

Elapsed:10 Ms.

Invoke

Invoke Xxxservice.xxxmethod ({"prop": "Value"})

The method that invokes the service.

Invoke Xxxmethod ({"prop": "Value"})

Method that invokes the service (automatically finds the service that contains this method).

4. View service Statuslook at the number of service calls, but oddly enough, I've just called onceQueryDemopagelist , which is shown here as 0 ( Seems to be not accurate, need to understand further)

Dubbo>count Com.test.DemoService
