Spring Proxying in Detail

It’s very common to refer to some Spring features as “magic.” How else could you add functionality like caching at the method level with nothing but a single annotation? Magic!✨ ✨ ✨

Proxying Technologies 🖥 ➡️ 🖥

Over time, I’ve come to learn the names of some of the magic ✨ that facilitates the amazing features of Spring that drive up the productivity of engineers and light a fire under the velocity of development teams.

JDK Dynamic Proxies and CGLIB.

Proxies in Spring are an implementation of the Proxy design pattern and help facilitate the paradigm of Aspect-Oriented Programming.

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.

In the modern computing environment, there are more users with heavier usage patterns and much higher expectations for user experience. Many applications are starting to be deployed on highly distributed cloud servers which come with their own set of complications.

To address these concerns, many engineering teams are turning to the Reactive Functional paradigm of programming.

This article will give you a brief introduction to Reactive Functional Programming.
