Working on a spring boot based application there is a requirement to add server sent events in the application. While browsing, I came across a solution using jaxrs. The question her is, can we use spring-boot-starter-jaxrs, spring-boot-starter-web dependency in the same gradle project?

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/
Version 1.5.4 was working fine without extra declaration of starter web in POM of Spring Boot Admin Clients. When I upgraded to 2.0.1, I had to add starter web to POM to make it work. Without starter web in client apps, there is no error or no log related to registering the application.
It's not documented anywhere as far as I know. Can anyone please confirm?
Spring Boot Admin 2.x can run on netty and on tomcat. So if you want to run on tomcat you have to explicitly import the spring-boot-starter-web.
The getting started guide contains this dependency http://codecentric.github.io/spring-boot-admin/current/#set-up-admin-server
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,

I would like to evolve my Spring application with a better architecture. The technologies I'm using are : spring portfolio ( spring mvc, spring test, spring Web, spring core, spring rest...)
Today I'm using packaging to structure the different layers of my application: models, services, api and of course web where I have my controllers.
I would like to know how can I use the power of spring boot to make a multi module maven architecture with an xml spring configuration for a Web application. I read that spring boot have an embedded tomcat and since I'm using eclipse with a separate tomcat server I would like to deploy my application on it and I think that this can create a problem.
I already found some links on github with this type of projects most of them are not elaboring an architecture of a Web application and use a class for spring configuration with the embedded tomcat that spring boot offers.
Thank you
Ps: sorry for my bad English
What you mean by multi module. If you want to build your jar for multiple environment you can use maven profile for it. Spring boot is nothing but a spring project which ease the configurations for you.
Regarding deployment to your own server, you have to convert the jar to war. Read "What about the Java EE Application Server" section of below link.

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.
