What are the advantages of Spring Boot? Why we need Spring Boot? Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications…
Let’s start with Spring
As we know the Spring is a heavyweight enterprise development framework Enterprise JavaBean (EJB) alternatives. Spring provides a relatively simple method for enterprise Java development.
Although Spring’s component code is lightweight, its configuration still is heavy (requires a lot of XML configuration). Spring 2.5 introduced annotation-based component scanning, which eliminated a lot of explicit XML configuration for the application’s own components. Spring 3.0 introduced the Java-based configuration, which is a type-safe reconfigurable configuration that can replace XML.
However, we still couldn’t escape the configured claw. When you enable certain Spring features, such as transaction management and Spring MVC, you still need to explicitly configure them with XML or Java.
And explicit configuration is also required when enabling third-party libraries, such as Thymeleaf-based Web views. Configuring servlets and filters (such as Spring’s DispatcherServlet) also requires explicit configuration in web.xml or servlet initialization code.
Although Component scanning reduces the amount of configuration. Java configuration makes it look simpler, but Spring still needs a lot of configuration.
Just configuring these XML files is a headache for Java developers and takes up most of the time and energy. In addition, the dependency of related libraries is very headache, and version conflicts between different libraries are also very common.
SO, Spring Boot comes and makes all that very simpler.
Why we need Spring Boot?
Firstly, let’s see the official introduction of Spring Boot:
Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”.
We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need minimal Spring configuration.
You can see that Spring Boot is Spring in essence. It does the Spring Bean configuration jobs that you had to do when in the past.
The Spring Framework is designed to simplify J2EE enterprise application development. And the Spring Boot Framework is designed to simplify Spring development. By this, it saves a lot of time in development.
The main advantages of Spring Boot
- Developing Spring-based applications is very easy.
- The Spring Boot project requires significantly less development or engineering time and usually improves overall productivity.
- Spring Boot does not require writing a lot of boilerplate code, XML configuration, and annotations.
- Spring boot applications can be easily integrated with the Spring ecosystem, such as Spring JDBC, Spring ORM, Spring Data, Spring Security, etc.
- Spring Boot applications provide embedded HTTP servers such as Tomcat and Jetty, making it easy to develop web applications. This is great! By the normal way to run Java programs can run Spring Boot web projects, which saves a lot of work.
- Spring Boot provides a command-line interface (CLI) tool for developing and testing Spring Boot applications such as Java or Groovy.
- Spring Boot provides a variety of plugins that allow you to develop and test Spring Boot applications using built-in tools such as Maven and Gradle.
