Introduction We will see how to implement circuit breaker pattern using Hystrix in Spring Cloud Gateway. Hystrix is a library from Netflix that implements the circuit breaker pattern. The Hystrix GatewayFilter allows us to introduce circuit breakers to our gateway routes, protecting our services from cascading failures and allowing us to provide fallback responses in the event of downstream failures….

Introduction Here we will see an example on WebSocket on Spring MongoDB Reactive Programming. In past we have see few examples on WebSocket but this example will use Spring WebFlux, i.e., WebSocket on Spring Reactive API. WebFlux includes reactive WebSocket client and server support. Both client and server are supported on the Java WebSocket API (JSR-356), Jetty, Undertow, Reactor Netty,…

Introduction In this three pages post we will see how to create Spring MongoDB Functional Reactive Microservices Example. We are going to use here Spring 5’s Webflux API. We will also see here how to use Flux and Mono with ServerResponse, ServerRequest in Handler function. We will know how to use RequestPredicates in Router function in subsequent sections. We will…

Introduction We will see here Spring Boot MongoDB Functional Reactive CRUD Example. We have seen our previous example on Spring Boot Functional Reactive Programming but we did not use any persistent storage like MongoDB but here we are going to use MongoDB for performing CRUD operations. We are going to use Spring 5’s Webflux API with reactive stream to implement…

Introduction This tutorial is about Spring Boot + Angular Functional Reactive Programming Example that will show you how you will create REST APIs using Spring Boot Functional Reactive Programming and consume these server side REST APIs using Angular Reactive Programming. We have seen in our example on Spring Boot Functional Reactive Programming, which you must go through first in order…

Reactive Programming This tutorial will show you an example on Spring Boot Functional Reactive Programming (FRP). Related Posts: What are Reactive and Functional Reactive Programming? Reactive programming is a declarative programming paradigm concerned with data streams and the propagation of change. In other words, Reactive Programming is a style of micro-architecture involving intelligent routing and consumption of events, all combining…
