Requirements Scenario
In a micro-service architecture, the way in which a requester of a service invokes a remote service is a problem that must be addressed. In the spring Cloud (Netflix) technology stack, each micro-service is exposed in the form of an HTTP rest interface, which normally requires an HTTP client to be used when executing a remote call, and then an HTTP request to the service. In fact, if you use Netflix's feign as an HTTP client, we

Perfect API design
Good API design specifications
Why is good application programming interface (API) design so difficult? Just throw together a few classes with a few basic methods on them and call it done.
You cocould do this, if you don't mind other developers cursing you-and referencing your API as an anti-pattern. How can this be avoided? Aim for perfection with API design. Yes, perfection.
Why is it always difficult to design well-designed application interfaces (APIS)? interfaces are not

If you want an iPad with a built-in 3G function, you need to add $130 to the standard iPad price and provide two simple traffic packages: $15 per month, M data traffic is allowed; or 25 USD per month, 2 GB Data traffic is allowed.

WarningFooConfiguration must have @ Configuration, but note that it is not in the @ ComponentScan of the main application context. Otherwise, it will be shared by all @ RibbonClients (that is, the default value of all clients is overwritten ).
