My framework is spring framework. core version is 4.3.16.RELEASE. Not using springboot. It's one of the legacy project.
And I wanna know what can I use the feign client without springboot.
Is this possible? and where can I found document about that.
thanks for your help :)
Yes, it's possible. You can find the documentation on their Github page.
Feign wasn't integrated with Spring initially. There is another wrapper library called Spring Cloud OpenFeign, and with it, you can use Feign in Spring Boot & Cloud applications more convenient (eg., you can use Spring's @RequestMapping annotation instead of default Feign's @RequestLine).
