When developing micro service applications using Java, the most common framework to use is Spring Boot. It streamlines development by providing user-friendly defaults for unit and integration tests, web apps, and more. 

Developers may save time and energy by using Spring Boot to create powerful apps with safe and transparent setups.

Various factors have contributed to Spring Boot’s prominence in the Java development community. In this post, we will look at 10 reasons why you should use Spring Boot in addition to a great deal of other information.

What is Spring Boot?

Spring Framework serves as the base for Spring Boot. It’s easy to use and facilitates speedier deployment, setup, and operation of web-based software.

It is an open-source technology that makes it simpler for developers to build independent digital products and production-ready spring programs, such as Java apps and web services. Because it is built on a micro framework, it is best suited for developing web and mobile app microservices.

10 Reasons Why You should use Spring Boot

When you use Spring Boot, your approach to Java programming chores will be completely revolutionized, and your experience will be simplified. 

1. Starters Exist For Everything

The libraries and default settings that make up Spring Boot Starters are described in a maven description. Additionally, Spring Boot applications may benefit from the functionalities provided by these starters. Looking to establish database connections? There is a prerequisite for that called a “starter.” Do you want to send emails or communicate with message queues? The spring boot fully covers it.

A startup dependency is available for most Spring Modules that automatically set up everything for you. Some third-party libraries even provide aid to Spring using starting modules. If you don’t have these baselines, it’s on you as the developer must keep track of all the dependencies and XML settings. That’s even more proof that Spring Boot is the way to go.

2. High-Quality Spring Boot IDE Support

All major IDEs support Spring Boot code help. IntelliJ IDEA Ultimate, for instance, includes excellent tools for code completion and navigation in Spring Boot applications.

3. Web Servers That Are Built In

The embedded Tomcat, Jetty, and Undertow servers are supported out of the box by Spring Boot. This eliminates the need for developers to install web applications on conventional application servers. You may switch between different server technologies if you have the right starter dependencies. You will end up with a JAR file capable of running in any environment that supports JAR files. The JAR boots up with all the necessary libraries and settings to function as an application server, ready to take requests.

Spring Boot applications may be easily converted from JAR to WAR and deployed on conventional servers if embedded ones are not desired.

4. Features Suitable for Production

Monitoring, analytics, and logging out of the box are just a few of the production-ready capabilities that come standard with Spring Boot. These capabilities save time and effort for developers by eliminating the need for different settings. Application status monitoring is made feasible by features like the health actuator endpoint. 

5. Speedier Development

Spring Boot takes a lot of judgments and has strong opinions on the Spring Ecosystem. This facilitates rapid setup and development by allowing the developer to get right to work.

FOR INSTANCE, many XML bean definitions and specialized servlet classes made Spring MVC feasible. However, with Spring Boot, all it takes is a startup dependency. There is zero configuration in XML for code creation at all.

6. Adaptation Curve

Learning Spring Boot is simple if you are familiar with the Spring framework. However, if you are unfamiliar with Spring, you will likely deal with business logic more often than Spring. To begin development, you must be familiar with a small set of annotations. 

7. Built-in support for JUnit

JUnit 5 is installed in all Spring Boot projects. If we need to initiate a test context, Spring Boot includes the @SpringBootTest annotation. Developers’ work is reduced to create test cases. They are freed from the burden of considering the intricate spring setting for each test scenario.

8. Spring Profiles

Spring Boot has a useful feature called Spring Profiles that helps distinguish distinct components of the application. Profiles allow you to activate or deactivate features depending on their context selectively. Depending on the circumstances, this might be useful when you need to swap out parts.

9. Various Deployment and Packaging Options

Different application packaging options are available inside the framework. You may make high-performance docker images without any additional settings or parameters.

It’s easy to launch or exit apps that use Spring Boot. Additionally, you may deploy these JAR files as Linux Services by performing a few additional steps. The JAR files, often known as FAT jars, include the application’s dependencies. This simplifies the deployment procedure. These builds are compatible with any computer with Java 8 or a later version.

10. Documentation 

For novice developers, the official documentation is all they need to get started with Spring Boot. All the benefits of the spring boot are described in great depth. The spring ecosystem also has its documentation for more in-depth explanations of individual modules.

Conclusion

Spring Boot is the preferred framework for many Java developers when creating microservices architecture apps. Because it has user-friendly options and a comprehensive toolkit with various instruments ranging from integrated servlet containers to running testing frameworks, this effective tool greatly simplifies the configuration and development process.
