Java-消耗运行在同一计算机不同端口上的Rest服务的最佳方法是什么？

Question

I am creating an application where I have to consume a RestFul service that is running at a different port of the same machine. I can definitely hard code url as "localhost:/url" in the client code but I dont think that is the best way to do it.

Answer 1

Is the decision accidental or inherent?

The proper action depends on the reason why the other service is running at a different port on the same machine. If the reason is accidental - ie at this moment, the service happens to reside on the same host, then you'd want the URL root be configurable. If the reason is inherent - ie there are two separate executables interacting through a REST interface but built, packaged, distributed and deployed as a single project, then you might want to ensure that they're on the same (virtual) machine by eg packaging them both in a single Docker container or something like that.
