In Spring Boot, Event-driven architecture is a paradigm, and it can be software component communication through the production, detection, and consumption of events. Spring Cloud Stream is a popular framework built on top of Spring Boot that can be used to simplify the development of event-driven microservices and provide the abstractions and tools to build, deploy, and scale event-driven applications effortlessly....

Spring framework was introduced for ease of Java application development. Later spring boot gained popularity for its easy-to-configure nature. To make the framework survive in the industry with demand for event-driver streaming architecture, Spring introduced a new framework named Spring Cloud Stream.

In enterprise applications, we use RESTful services to establish the communication between client and server. The general idea is that the client sends the request to the server and the server responds to that request with some response. Generally, we have three different layers in most of the application Web Layer, Business Layer, and Database Layer. The objects in these layers are mostly different from each other. For example, The web layer object is completely different from the same object in the database layer. As database objects may contain fields that are not required in the web layer object such as auto-generated fields, password fields, etc....

The Spring Web Flux provides different applications to developers to develop asynchronous, non-blocking web applications by using Mono, Flux, and other classes. In this article, we will be learning to write a basic Hello World program in Spring WenFlux....

Eclipse is an Integrated Development Environment (IDE) used in computer programming. It includes a base workspace and an extensible plug-in system for customizing the environment. It is the second-most-popular IDE for Java development. Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including C, C++, C#, Groovy, JavaScript, etc. Similarly, Spring Tool Suite (STS) is a java IDE tailored for developing Spring-based enterprise applications. It is easier, faster, and more convenient. And most importantly it is based on Eclipse IDE....

Spring Security is a framework that allows a programmer to use JEE components to set security limitations on Spring-framework-based Web applications. In a nutshell, it’s a library that can be utilized and customized to suit the demands of the programmer. Because it is a part of the same Spring family as Spring Web MVC, it works well together. The most significant benefit of this framework is that it is both strong and very adaptable. Although it adheres to Spring’s set-up conventions, programmers may select between default provisions and modify them to their specific requirements. Read more on Spring Security and its Features in this article Introduction to Spring Security and its Features....
