Feign
A Java HTTP client binder that simplifies writing declarative HTTP API clients using annotations.
What is Feign?
Feign is a Java HTTP client binder that simplifies writing HTTP API clients by using declarative annotations on Java interfaces. It processes annotations into templatized HTTP requests, reducing boilerplate code and making it easier to integrate with text-based HTTP APIs. It solves the complexity of uniformly binding Java code to various HTTP APIs, whether RESTful or SOAP-based.
Java developers building HTTP API clients for microservices, REST APIs, or SOAP services who want a declarative, annotation-driven approach with minimal overhead.
Developers choose Feign for its simplicity, extensibility, and strong integration ecosystem—it supports various encoders/decoders, HTTP clients, and tools like Hystrix for circuit breaking, all while maintaining a clean contract-based design that is easy to unit test.
