Spring Boot is an opinionated addition to the Spring platform, focused on convention over configuration — highly useful for getting started with minimum effort and creating standalone, production-grade applications.
Why should we use Spring Boot Framework?
We should use Spring Boot Framework because:
The dependency injection approach is used in Spring Boot.
It contains powerful database transaction management capabilities.
It simplifies integration with other Java frameworks like JPA/Hibernate ORM, Struts, etc.
It reduces the cost and development time of the application.
Along with the Spring Boot Framework, many other Spring sis
How to Setup Sping Boot?
Step 1: Open the Spring initializr https://start.spring.io.
Step 2: Provide the Group and Artifact name. We have provided Group name com.myapp and Artifact spring-boot-example.
Step 3: Now click on the Generate button.
Step 4: Extract the RAR file.
Step 5:
Import the folder.
File -> Import -> Existing Maven Project -> Next -> Browse -> Select the project -> Finish
Step 6: Run the SpringBootExampleApplication.java file.
Advantages of Spring Boot:
It creates stand-alone Spring applications that can be started using Java -jar.
It tests web applications easily with the help of different Embedded HTTP servers such as Tomcat, Jetty, etc. We don't need to deploy WAR files.
It provides opinionated 'starter' POMs to simplify our Maven configuration.
It provides production-ready features such as metrics, health checks, and externalized configuration.
There is no requirement for XML configuration.
It offers a CLI tool for developing and testing the Spring Boot application.
It offers the number of plug-ins.
It also minimizes writing multiple boilerplate codes (the code that has to be included in many places with little or no alteration), XML configuration, and annotations.
It increases productivity and reduces development time.
Goal of Spring Boot :
The main goal of Spring Boot is to reduce development, unit test, and integration test time.
Provides Opinionated Development approach
Avoids defining more Annotation Configuration
Avoids writing lots of import statements
Avoids XML Configuration.
