How to Implement Feign Client in Spring Boot Microservices? Feign Client java Microservices Spring Boot Spring Cloud by devs5003 - May 10, 2024May 3, 20269 When two web applications communicate with each other for data exchange, they work on Producer-Consumer technique. An application who produces data is known as a Producer/Provider application. Similarly the one who consumes data is known as Consumer application. As a Java developer, we might be very familiar with REST API for Producer application whereas RestTemplate for Consumer application. With Microservices based application also, two Microservices communicate with each other and follow the Producer-Consumer model. Here, in consumer side, we use a concept 'Feign Client' as a better option instead of RestTemplate in order to minimize our effort of coding. Therefore, our topic of discussion is 'How to Implement Feign Client in Spring Boot Microservices?'. Apart from consuming REST services in an
