Question

when we use microservice architecture, the port is unimportant, so we always use 0（server.port）or -1（dubbo.protocol.port）to use a random port.
But shenyu will just use 0 and -1 when running.
Is there any way to get it to the actual port? Or must I use a fix port when I use shenyu?

    @yu199195 I upload a demo.
    I use random tomcat port(set server.port=0) and random dubbo port(set dubbo.protocol.port=-1), tomcat and dubbo will use a random usable port, but shenyu will print error log like below
