It gives defaults to code, and annotation configurations to snappy begin new spring projects at no time. It takes after “Opinionated Defaults Configuration” Approach to escape from a lot of standard code and configuration to enhance Development, Unit Test, and Integration Test Process.
Here are some of the various advantages of using Spring Boot:
The reason behind to have Spring-boot-maven module is it gives a couple of charges which empower you to package the code as a container or run the application
The Spring Initializer is a web application that can produce a Spring Boot project structure for you. It doesn’t create any application code. However, it will give you an essential project structure and either a Maven or a Gradle build specification to fabricate your code with. You should simply compose the application code.
