I have a requirement that I have to use Spring Boot with JSF as user interface, as of now I am using JSF with spring other modules. So, I want know the similarities, differences and advantages of Spring boot over Spring other modules.
Long story short, Spring Boot is highly opinionated wrapper for Spring Framework with a lot of production and cloud ready features. It can significantly reduce amount of your configuration if you follow conventions.
Start reading here.
You can not compare spring boot and spring framework. Spring Boot is a new project aims to help spring development by auto configuration of things required to run the spring application.
So, if you have spring application, you can use spring boot to run your Spring application without worrying about writing the XML configuration.

I am in the process of building a set of shared libraries using custom Spring Boot starter auto configuration per guidance from https://docs.spring.io/spring-boot/docs/2.6.7/reference/htmlsingle/#features.developing-auto-configuration. Great feature offered by Spring Boot by the way! My question is that how does Spring Native support these types of custom Spring Boot Starter libraries? Are extra reflection configurations or native hints required? I have been evaluating Spring Native and I am very excited about the performance boost it brings to Spring Boot apps! I am eagerly awaiting Spring Boot 3 GA to be released! Any advice on how Spring Boot 3 and/or Spring Native handles custom Spring Boot starter libraries and if any extra configurations are required will be greatly appreciated!
I reached out to Sébastien Deleuze, one of the members on Spring Native team, and his response to my question is as follows. Thanks Sébastien!
"Spring Native and the upcoming Spring Boot 3 should support this kind of autoconfiguration if they follow certain guidelines, like using #Configuration(proxyBeanMethods=false).
See https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/#how-to-contribute-design for more details.
Spring Boot 3 will likely define more clearly the guidelines."
I have a set of projects in Spring framework and I have to Find the ones which can be converted to Spring boot.
Is there anything that is related to Spring framework and cannot be converted to spring boot ? In my research, I Could not Find something like that.
But does anyone know something, like a dependency, which would force the project to stay in Spring framework ?
Spring Boot uses the Spring Framework as a foundation and improvises on it. It simplifies Spring dependencies and runs applications straight from a command line. Spring Boot provides several features to help manage enterprise applications easily. Spring Boot is not a replacement for the Spring, but it’s a tool for working faster and easier on Spring applications. It simplifies much of the architecture by adding a layer that helps automate configuration and deployment while making it easier to add new features.
Most of the changes for migrating Spring Framework application to Spring Boot are related to configurations.This migration will have minimal impact on the application code or other custom components.Spring Boot brings a number of advantages to the development.
It simplifies Spring dependencies by taking the opinionated view.
Spring Boot provides a preconfigured set of technologies/framework to reduces error-prone configuration so we as a developer focused on building our business logic and not thinking of project setup.
You really don’t need those big XML configurations for your project.
Embed Tomcat, Jetty or Undertow directly.
Provide opinionated Maven POM to simplify your configurations.
Application metrics and health check using actuator module.
Externalization of the configuration files.
Good to refer this for migrating from Spring to Spring Boot application: https://www.javadevjournal.com/spring-boot/migrating-from-spring-to-spring-boot/
I've found quite a huge pile of topics that give the answer for the opposite question: "Why choose Spring Boot over Spring?", but I guess somebody can give an example that will justify Spring selection over Spring Boot.
You can found several cons on Spring boot over Spring, mainly missing learning steps in Spring and support and if using monolithic application
If you are new to Spring and want to learn how the dependency injection, AOP programming, and proxies work, starting with Spring Boot is not a good choice. Spring Boot hides the most of these details from you.
If you are not familiarized with other projects of the Spring ecosystem (Spring Integration, Spring AMQP, Spring Security, etc), using them from Spring Boot will make you miss a lot of concepts
In a large and monolithic based applications, I wouldn’t encourage you to use Spring Boot
Also can increase deployment size
Spring boot may unnecessarily increase the deployment binary size with unused dependencies.
I'm looking to learn Spring Security with Grails but I can't find any intensive course that is built with Grails. My question is, since Grails 3 is built on top of Spring Boot, can I use Spring Boot Spring Security configuration for my Grails 3 app?
Yes.
There are several security related Guides at http://guides.grails.org.
Some documentation you might find helpful:

One of the Spring framework advantage is dependency injection. Many had used SpringBoot for providing REST Web Services.
Read up and notice there are Scheduler and CommandLineRunner for SpringBoot, could we using SpringBoot for backend type of application to replace the usual standalone java program while making use of SpringBoot advantage (Dependency Injection)
- Cron Job (Execute and stop running)
- Long Running Process
One of the main thing I am looking into is to use annotation such as Spring Configuration, Spring Data JPA and other technology in backend application.
Of course!
I used spring boot to back CLI projects, DB access projects and more.
Spring boot is very modular. It works by providing auto-configuration based on your maven/gradle imports. If you don't import starter-web/starter-jersey or any other starter that is for the web/rest api, the auto-configuration for this resources won't be triggered and you can basically enjoy all the power of spring boot to support your needs
Definitely,
Spring boot is not a separate framework.It reduces the configuration difficulties when you using spring framework. Spring boot provides a Rapid Application Development using without complex configuration including your dispatcher servlet, XML file for database connectivity and configuration files. You can use spring boot for back-end development. Simply says you can do everything what you does in spring MVC without any complex configuration. If you are using spring boot , You can configure your database details in application.properties file. I am adding one of two links for proper reading,
