Java Spring Boot: Why is Spring Framework Extremely Famous

Java Spring Framework (Spring Framework) is a well-liked, open-source, corporate-level system for building independent, high-quality Java Virtual Machine apps (JVM).

Through its three primary features, Java Spring Boot (Spring Boot) is a platform that accelerates and simplifies the creation of web apps and microservices with the Spring Framework. The three features are:

●Autoconfiguration.
●Taking a position on configuration.
●Being able to develop standalone applications.

With the help of this tool, you may create a Spring-based application with the least amount of preparation and setup.

Why is Spring Framework so Popular?

Dependency injection is a functionality of the Spring Framework that enables classes to specify their unique dependencies, which the Spring container will later inject into them. As a result, engineers can create modular applications with loosely linked components that are perfect for distributed network apps and microservices.

Typical tasks that an app must do, including type conversion, data binding, exception handling, validation, internationalization, event management and resource, and much more, are also supported natively by the Spring Framework. It interfaces with a number of Java EE technologies, including AMQP (Advanced Message Queuing Protocol), RMI (Remote Method Invocation), and Java Web Services,. In conclusion, Spring Framework gives programmers all the features and tools they require to build loosely connected, cross-platform Java EE apps that function in any setting.

Benefits of Java Spring Boot

Even though the Spring Framework is powerful and complete, configuring, setting up, and deploying Spring apps still requires significant effort and expertise. Spring Boot reduces this work with three crucial features.

Autoconfiguration

Apps are launched with pre-defined dependencies through autoconfiguration, so you do not need to set them up explicitly. Due to built-in autoconfiguration features, Java Spring Boot manually configures the core Spring Framework and third-party modules according to your preferences (and based on the standard practices, which allow avoidance of errors). Despite the fact that you can change these settings after setup is finished, Java Spring Boot’s autoconfiguration functionality makes it easier for you to get started creating Spring-based apps quickly and lowers the likelihood of human errors.

Opinionated strategy

Based on the requirements of your project, Spring Boot adopts an opinionated strategy for integrating and setting startup dependencies. Instead of having you make all of those choices and configure things yourself, Spring Boot decides which packages to download and which preset variables to use.

However, during the launch phase, when you select from a variety of starter dependencies known as Spring Starters that helps to solve use scenarios, you can specify the requirements of your application. You can use Spring Boot Initializr without writing any code by completing a short web form.

Roughly 50 Spring Starters are included in Spring Boot, and there are many more third-party starters accessible.

Standalone Programs

Spring Boot enables programmers to build ready-to-use applications. By integrating a web server like Tomcat or Netty inside your app during the startup phase, it specifically enables you to construct standalone applications that function independently, without depending on an exterior web server. As a result, by just selecting the Command prompt, you may run your program on any system. You can disable this capability to create apps without an integrated Web server.

Spring Framework Vs. Spring Boot

Again, convenience and quicker development are the main benefits of Spring Boot over Spring Framework alone. The increased freedom you have from directly interacting with Spring Framework is theoretically sacrificed in order to achieve this.

But in reality, adopting Spring Booth is worth the sacrifice unless you want or want to develop a really special configuration. You can still take advantage of the well-regarded annotation system in the Spring Framework, which makes it simple to add additional dependencies (not covered by Spring Starters) to your application. Additionally, you continue to have access to all of the features of the Spring Framework, such as validation, simple event handling, type conversion, built-in security, testing capability and data binding. In conclusion, Spring Boot can greatly speed up production if even just one Spring Starter can handle the breadth of your project.

Most Important Features of Java Spring Boot

Lightweight

In terms of size and capability, the Spring Framework is quite small. This is a result of its POJO architecture, which does not need it to apply any interfaces or inherit any classes.

Aspect-Oriented Programming (AOP)

This plays a crucial role in the Spring Framework. Cross-cutting issues (such as security, logging, etc.) are divided from the app’s business rules using aspect-oriented programming. You will gain more in-depth information about this in the articles that follow.

Transaction Control

This is used to manage activities for Java objects and integrate various transaction processing APIs. Additionally, it may be utilized in containerless contexts and is not dependent on the J2EE framework.

Container

The Spring framework plans and controls the settings and lifespan of application components.

Dependency Injection

The Spring Framework’s capability enables the creation of loosely connected applications. As a result, it is simpler to unit test these weakly linked programs. Additionally, this enables the developer to replace certain modules as needed.

Compatibility to Other Frameworks

This framework’s ability to avoid attempting to tackle issues that have previously been resolved is fantastic. It only makes an effort to incorporate them into its framework, which offers a solution to bigger issues. Hibernate,  IBATIS, Toplink, and other systems might be examples of this.

Goals of Java Spring Boot

The objectives of Spring Boot’s design are as follows:

● To keep Spring’s XML settings simple.
● To more easily create production-ready Spring apps.
● To speed up application development and make it independent.
● Describe a simpler approach to launching the program.
