How to Implement Feign Client in Spring Boot Microservices? Feign Client java Microservices Spring Boot Spring Cloud by devs5003 - May 10, 2024September 18, 20249 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
How to register Microservices in Eureka Server java Eureka Microservices Spring Cloud by devs5003 - March 4, 2024March 11, 20249 In the series of Microservices Tutorial, we have already discussed on Microservices Architecture and Microservices in Java in a theoretical way. Now in this article, we will create an example by using Netflix Eureka in the context of Microservices. We will use Netflix Eureka to register & discover Microservices. In order to make intra-communication happen between multiple micro services, it is mandatory to register & discover them in the application. It is possible by using Netflix Eureka Server. Hence, we will talk about 'How to register Microservices in Eureka Server?' in this article. In order to make communication happen among all microservices in an application, there should be a common medium. Subsequently, that common medium should have details of all microservices
How to implement Fault Tolerance in Microservices using Resilience4j? Resilience4j java Microservices Spring Boot Spring Cloud by devs5003 - February 24, 2024February 27, 20246 When we develop an application, especially a Microservices-based applications, there are high chances that we experience some deviations while running it in real time. Sometimes, it could be slow response, network failures, REST call failures, failures due to the high number of requests and much more. In order to tolerate these kinds of suspected faults, we need to incorporate Fault Tolerance mechanism in our application. To achieve it, we will make use of Resilience4j library. Resilience4j is a lightweight, easy-to-use fault tolerance library inspired by Netflix Hystrix, but designed for Java 8 and functional programming. So, our focus in this article will be on 'How to implement Fault Tolerance in Microservices using Resilience4j?' After implementing the Fault Tolerance in Microservices using Resilience4j,
