Spring vs Spring Boot: An in-depth Comparison

Spring Boot is used to configure and layout the entire framework needed by Spring applications by providing a number of configuration attributes. The application developer can focus on coding only the portions of their application that are business-specific, while Spring Boot takes care of configuring all of the external functionality. When compared to traditional Spring application development, you can get an application up and running in considerably less time because all of the boilerplate code is taken care of for you. So the answer is Spring Boot.

Spring Boot is not suitable for large-scale projects. The reason is that the automatic configuration of Spring Boot creates a lot of unused dependencies, resulting in large deployment packages.

Spring Boot is a framework that includes everything you need to create web applications and microservices, making it easy to develop and deploy applications. It is mainly used in developing REST APIs.

Spring Boot DevTools allows installing, configuring and running different versions of a Spring Boot application and its dependencies on your local machine. It provides an editor that allows you to change any configuration file or add an additional dependency.

Once the application is configured, running it is as simple as pressing a button. Spring Boot DevTools automatically configures ports and so that you can access the service from a browser.
It also comes with a Chrome extension that can be used to debug HTTP requests.

Spring Boot will not be a replacement for the Spring framework. It only makes working with Spring faster and easier. Spring Boot is an opinionated framework designed to allow Spring-based applications to stand on their own. It provides a base configuration that enables developers to quickly get started building Spring-based applications.

If you are looking to develop a project with Spring, then chances are that you will be working with a specific version of Java to make everything work properly. So, it might be that the older versions of Java are not compatible with Spring, and you will need to update the Java version that you are using for everything to work properly.

However, if you are looking for compatibility between older versions of Java and Spring, then it is possible this can be done as long as both are compatible with each other. In some cases, older versions of Java might not be compatible with newer versions of Spring, so this would require some more adjustments and work on your part.
