This article is about when you should implement retry in your project, why you want to retry/call backend services again, and what options you have. Retry is the ability to re-invoke (re-run) a failed operation. When the cause of the failure is temporary or transient, it is a good feature. …

In this example, we’ll see the way to perform the Bean validation using the Spring WebFlux Validation. pom.xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId>…

In this example, we’ll take a look at the Spring WebFlux Error Handling using @ControllerAdvice. While calling the services/micro-services anything could go wrong and result into 500 “Internal Server Error ” as shown below error: { "timestamp": "2022-05-05T03:42:10.982+00:00", "path": "/employee/all", "status": 500, "error": "Internal Server Error", "requestId": "3101b004-1" } Usually…

In this example, we’ll look at the Spring WebFlux WebSocket communication using the real time client-server communication. The client will send a message(s) to the server via WebSocket connection. The server will receive the string message and just modify it (ex: uppercase) it and respond to the client. Spring WebClient…

เป็นหนึ่งใน Framework ที่ได้รับความนิยมค่อนข้างสูงในโลกปัจจุบัน หลักการของ Spring Boot นั้นได้รับอิทธิพลมาจาก Spring Framework โดยตรง กล่าวคือ การควบคุมทั้งหมดจะย้ายไปอยู่ส่วนที่เรียกว่า Application Context และควบคุมผ่านการ Configuration โดยมี Controller กำหนดการทำงาน ซึ่งจะมี Controller อยู่ 2 แบบได้แก่ @Controller สำหรับสร้าง Web Application และ @RestController สำหรับสร้าง Web Service นอกจากนี้ Spring Boot ยังมีความสะดวกสำหรับการนำไปใช้พัฒนา Application เนื่องด้วยการทำงานที่เป็นแบบ Auto Configuration ประกอบกับมีเซิร์ฟเวอร์ built-in มาให้ในตัวพร้อมใช้งาน…

In this article, will see how we could use Spring WebFlux WebClient for making non-blocking HTTP requests. WebClient — Non-blocking, reactive client to perform HTTP requests, exposing a fluent, reactive API over underlying HTTP client libraries such as Reactor Netty. Use static factory methods create() or create(String), or builder() to prepare…

WebFlux is part of Spring Framework which helps to achieve a programming paradigm that promotes an asynchronous, non-blocking, event-driven approach to data processing known as reactive programming. Reactive systems have certain characteristics that make them ideal for low-latency, high-throughput workloads. but what does that mean? …

Reaktif Programlama Nedir ? Nasıl Çalışır ? Reaktif programlama declarative programlama paradigmasını ele alan bir metodojidir. Bu paradigma aslında 2014 yılında Jonas Boner tarafından yayınlanan manifesto üzerine kurgulanmıştır. Bu metodolojinin en önemli katkısı async ve non-blocking bir yapı sunmasıdır. Bu yapının çalışma mekanizması event streaming üzerinden yürütülmektedir. Genelde geleneksel servlet mimarilere göre daha az thread ile gelen…

In this story, we are going to implement multi-tenancy using Spring Boot WebFlux and MongoDB. Multitenancy applications allow multiple customers or tenants to use a single resource without seeing each other’s data. This is highly common in SaaS solutions. …
