Introduction to Spring WebFlux

Spring WebFlux provides reactive, async, non-blocking programming support for web applications in an annotated Controller format similar to SpringMVC.

This approach is similar to how Node.js uses an async, non-blocking model which helps make it more scalable. Spring WebFlux uses a similar model but with multiple event loops.

Spring WebFlux moves away from the thread-per-request blocking model in traditional SpringMVC (with Tomcat by default) and moves towards a multi-EventLoop, async, non-blocking (with Netty by default) paradigm with back-pressure that is more scalable and efficient than traditional blocking code.

Spring vs Spring BooDifference Between Spring and Spring Boot

As an extension of the Spring Framework, Spring Boot is widely used to make development on Spring faster, more efficient and convenient. In this article, we will look at some of the parameters were using Spring Boot can drastically reduce the time and effort required in application development.

Spring Native turns Spring apps into native executables

Spring Native beta release leverages GraalVM to compile Spring Java and Kotlin applications to native images, reducing startup time and memory overhead compared to the JVM.

Spring Native, for compiling Spring Java applications to standalone executables called native images, is now available as a beta release. Native images promise faster startup times and lower runtime memory overhead compared to the JVM.

Launched March 11 and available on start.spring.io, the Spring Native beta compiles Spring applications to native images using the GraalVM multi-language runtime. These standalone executables offer benefits including nearly instant startup (typically fewer than 100ms), instant peak performance, and lower memory consumption, at the cost of longer build times and fewer runtime optimizations than the JVM.

Spring Framework Tutorial

What is the spring framework in Java?

The spring framework is one of the most versatile frameworks in java which is used to bring down the complexity of the development of enterprise-grade applications. The first production release of the spring framework was in March 2004 and since then, this robust and open-source framework has gained tremendous popularity, so much so that it is often referred to by developers all around the world as the “framework of frameworks”. Spring is a loosely coupled, open-source application framework of java. It is lightweight and the inversion of the control container for the Java platform. A large number of Java applications use the core features of the spring framework. In addition to that, extensions have also been developed to allow developers to develop Web Applications on top of the Java Enterprise Edition platform.

Introduction to Spring Boot and JDBCTemplate: Refactoring to SpringData JPA

Introduction to Spring Boot and JDBCTemplate: Refactoring to SpringData JPA.

Refactoring is the process of modifying a software system without changing its desirable behavior. It was necessary to have an application integrated with the relational database using the Spring JDBC Template in the first parts. The Spring JDBC Template is a powerful tool that facilitates productivity. However, there is a way to simplify the code even further with Spring Data JPA. The purpose of this post is to refactor the project to use Spring Data JPA.

Spring Data JPA, part of the larger Spring Data family, makes it easy to implement JPA-based repositories easily. This module deals with enhanced support for JPA-based data access layers. It makes it easier to build Spring-powered applications that use data access technologies.

A safe code refactoring requires the use of tests to ensure that the compartment is not changed. The use of tests, fortunately, is adopted as a minimum standard, including several methodologies such as TDD that preach the creation of tests at the beginning of the development process.

Spring MVC Async vs. Spring WebFlux

1. Introduction

In this tutorial, we’ll explore the @Async annotation in Spring MVC, and then we’ll get familiar with Spring WebFlux. Our goal is to have a better understanding of the difference between these two.

2. Implementation Scenario

Here, we want to choose a scenario to show how we can implement a simple web application with each of these APIs. Moreover, we’re especially interested to see more about thread management and blocking or non-blocking I/O in each case.

Let’s choose a web application with one endpoint that returns a string result. The point here is that the request will pass through a Filter with a small 200ms delay, and then the Controller needs 500ms to calculate and return the result.

Next, we’re going to simulate a load with  Apache ab on both endpoints and monitor our app behavior with  JConsole.

It may worth mentioning that in this article, our goal is not a benchmark between these two APIs, just a small load test so we can trace the thread management.
