Spring and Spring Boot are among the popular frameworks in the Java developer community. The flexible, versatile features of Spring enable developers to build a wide range of business-critical applications, from simple to complex. However, the versatility of Spring technology is both a strength and a weakness for developers. The inclusion of numerous complex procedures and choices at the programmer’s disposal makes the entire process intricate.
Hence, to minimize these complexities, Java extended Spring application and introduced Spring Boot. Although Spring Boot is an extension of the Spring Framework, it offers many advantages, particularly by enabling developers to build applications more easily. Easier means it helps developers make choices regarding dependency management and configuration.
Introduction to Spring and Spring Boot:
Spring Boot is an extension of Spring, developed after Spring was introduced. It was in early 2000 that the Spring Framework was introduced. Soon after its introduction, Spring Framework became a popular choice among the Java developer community, especially for enterprise-grade applications. In later years, Spring Boot gradually replaced the Spring Framework due to its added benefits. They include enabling developers to build applications more easily than with the Spring Framework.
Moreover, unlike the Spring Framework, Spring Boot does not require tedious configuration choices and helps teams get started quickly. Making it is an ideal choice, particularly while building standalone applications. Another main advantage of Spring Boot is that it allows access to all the capabilities and tools of Spring without adding any complexities of the Spring Framework.
Why are these Frameworks Popular among the Java developer community?
Spring offers an array of exceptional baseline technologies, including dependency, type conversion, data binding, internationalization, event management, and aspect-oriented programming. In addition, it includes task scheduling, remoting, Model-View Controller web applications, data objects, mocking, testing, and many other features. With the inclusion of several features, there are ample opportunities for the development team and software architects to select the best features based on the requirements of the ongoing project.
Furthermore, there are many subprojects within the Spring framework that focus on event management, data access, credentials management, security, cloud apps, and, most importantly, artificial intelligence. However, the inclusion of several features offers more flexibility for developers, which can lead to complexity. Sometimes it is difficult for developer teams to choose the best option, as it offers several configurations, choices, and options. And after installing the software manually, the coding process becomes more difficult because it is hard to change the entire procedure.
Spring Boot Rescue Developers from Programming Complexities:
Spring Boot helps developers make the best choices when using the software. For instance, if a developer is working on a particular application that needs an embedded web server. Spring Boot not only determines whether a web server is needed but also installs and configures it automatically. In contrast, in a Spring application, the developer must not only decide which web server to use and install but also manually configure the chosen settings, including security settings. Thus, it is another important example of why developers choose Spring Boot over Spring. Here, the advantage of Spring Boot is that it offers developers a good set of options.
Spring and Spring Boot: Which is the Programmer’s Choice?
For many reasons, Spring Boot offers greater flexibility, intelligence, a wider codebase, and many more. Hence, it is the developer’s choice. Below is the detailed explanation.
Spring Boot is Intelligent:
It is widely regarded as “intelligent” because it enables an algorithmic, opinionated approach, particularly to automate complex configurations in Java enterprise applications.
Spring Boot is lightweight:
Although Spring Boot is an extension of the Spring technology, it is lightweight. As the extra weight from the extension features does not get transferred into the completed app. But installs only the feature that the app requires.
Wider Codebase of Spring Boot than Spring:
Since Spring Boot is an extension of Spring, the codebase is larger than Spring’s.
Ability to Self-Configure:
Spring Boot can intelligently configure modules and libraries; however, the Spring Framework lacks such configuration. Here, the term intelligently self-configuring is also known as “opinionated”. Although the term “intelligence” is used for Spring Boot’s configuration, it does not refer to AI; it simply reflects algorithmic choices. Once Spring Boot understands what type of application the developer is building, it selects the necessary third-party libraries and modules and loads only those.
Reduces Complexities:
When choosing between Spring and Spring Boot, developers need to balance ease of use and complexity.
Although Spring provides boundless options, it also consumes much of a developer’s time, as choosing among the available options takes a long time. Developers also need to not only select the types of modules or third-party libraries to install, but also spend time configuring those functions and features. All these prioritizations should be completed before starting to code.
In contrast, Spring Boot allows the developer to complete the setup process quickly, as the framework itself can determine which types of installations and configurations the application requires and does so easily. However, one drawback is that the developer cannot customize the process; it can be ignored, as the issue is negligible.
When to use?
Given the above differences, developers can choose between Spring Boot and Spring based on the application type. While Spring Boot is a better choice for developing web-based applications and microservices, in special cases, Spring might be the option for very large projects.
Spring and Spring Boot: Key Points in Summary
While Spring is a highly robust and complex framework for building enterprise-grade Java applications, Spring Boot is much easier to use. For example, developers need to choose from a wide range of options for Spring Framework, but Spring Boot is a lightweight, customized toolbox designed to perform a specific job. However, developers can use either Spring or Spring Boot to build modular Java applications.
Importantly, Spring Boot offers additional benefits, particularly when developing smaller-scale applications such as web apps and microservices. These applications require smart defaults and simplified configuration to enable the software development team to deploy them quickly.
Likewise, if the team is building a complex, large application, the Spring Framework might be a good choice, as it offers greater flexibility.
Lastly, while Spring is the main application, Spring Boot is the subproject of Spring. These frameworks are both open source and are available under the Apache 2.0 license.
