背景
开发经常需要测试dubbo服务接口，除了dubbo admin控制台的入口外，我们还可以通过telnet命令来实现。
从
2.0.5版本开始，dubbo 开始支持通过 telnet 命令来进行服务治理。
telnet localhost 20880
Trying localhost...
Connected to localhost.
Escape character is '^]'.
命令
ls
ls
com.xxx.service.CarAuditService
com.xxx.service.CarStageService
com.xxx.service.CarService
com.xxx.service.AssetCarService
cd
cd com.xxx.service.CarService
Used the com.xxx.service.CarService as default.
You can cancel default service by command: cd /
invoke
dubbo>invoke listCar({"class":"com.xxx.entity.CarPageReq","includeCarIds":[132586]})
Use default service com.xxx.service.CarService.
{"code":10000,"data":{"items":[{"color":"紫色","colorId":10,"status":3}],"pageNum":1,"pageSize":1,"total":1},"msg":"Success","traceId":"18f94fb98cea4b22aaf7b0e44bccca40"}
