How to Use Spring Retry Template

In the cloud computing world, one of the pivotal parts is networking, the fact is that we cannot avoid network glitches and there will be temporary disconnection for a couple of seconds which makes the operations break while doing network-related configuration from the cloud-native applications. I am going to talk about one of the solutions in Java with spring-context on how to use the Spring Retry Template to handle the failure operations. We will build a small application and see how Spring Retry Template works.

How Does Spring Boot Auto-Configuration Work?

What Is It?

As its name implies, "autoconfiguration" helps you to configure your Spring Boot application automatically. More precisely, it automatically create beans for you! Strangely, it is a cool feature, but not applicable outside of Spring Boot. 

The Purpose and Method

The purpose is simple: to save you time when you create beans, which is usually done by yourself. It sounds like magic, but behind the scene, it's nothing fancy actually. 

Spring Bean Lifecycle

Spring (Coffee) Bean Lifecycle

The Spring IoC (Inversion of Control) container manages Spring beans. A “Spring bean” is just a Spring-managed instantiation of a Java class.

The Spring IoC container is responsible for instantiating, initializing, and wiring beans. The container also manages the life cycle of beans.
