pretend, a feign inspired declarative HTTP client

Very cool. Support for a lightweight HTTP client like ureq or minreq would be awesome though, since often times I will create a simple crate that does basic HTTP requests to a basic API (or just download a tarball or two), but don't want to have to import an entire async runtime stack and complex feature-complete HTTP client into what is otherwise a small library.

Introducing SpecMock: Easily create mock Server for @Controller and @FeignClient in exist class!

Testcontainers is the latest goto for integration tests that involves JPA tests, API tests etc. recently i tried this over unit tests and it was pretty awesome. I no longer had to mock all the unnecessary dependencies. All I had to worry about was my input and output and most importantly the tests were executed over a live environment instead of a mock. On a side note, recently docker acquired testcontainers so I am guessing of some good features down the pipeline for integration. More on reddit.com

Colon character getting encoded as %3A in PathVariable while using in Feign Client

All I want is, it should remain as it is in path variable of my feign client api. Why? It will get decoded on the receiving end, and : is not considered 'url safe'. More on reddit.com

Navigating Client-Server Communication with Spring’s @FeignClient Annotation

March 30, 2026 - When a microservice wants to call another service’s API, developers often use HTTP clients or REST templates to make those calls. Although these are functional methods, they entail a lot of boilerplate code, making the codebase harder to maintain and understand. The @FeignClient annotation streamlines this process by abstracting the HTTP client layer, allowing developers to focus more on business logic and less on infrastructural concerns.

r/SpringBoot on Reddit: When to use Open Feign and when not?

April 28, 2024 -

I want to write a simple REST POST API , this will be invoked by cross team to send json data and then I have to process this data and give status OK back as response, if validation passes.

Since I am going to use all new tech stack, Java 21, Spring 3.2.5 I am confused on using Open Feign .

Since REST template is deprecated I want to make choice between open feign and wen Client.

will it be good to use Open Feign here in above small use case ?
Does cross team who willing to call my endpoint have to write code using Spring cloud open feign too?
Any other cons to consider?

OpenFeign vs WebClient: How to Choose a REST Client for Your Spring Boot Project

June 5, 2025 - A basic OpenFeign client looks like this: @FeignClient(name = "book-service") public interface BookClient { @GetMapping("/books/{id}") User getBookById(@PathVariable("id") Long id); } You can then inject BookClient like any Spring Bean: @Service public class BookService { @Autowired private BookClient bookClient; public User getBook(Long id) { return bookClient.getBookById(id); } } OpenFeign is well integrated with Spring Cloud Discovery Service (Eureka), Spring Cloud Config, and Spring Cloud LoadBalancer.
