Spring MVC or Spring Boot [closed]
(5 answers)
Closed 5 years ago.
just starting out learning Spring, could you tell me the main differences between Spring Boot and MVC?
Which one is recommended for a beginner?
Thanks.
Spring MVC is a project within the Spring Framework for implementing the model-view-controller design pattern. It is used to build dynamic (and static sort of) web pages and ReSTful webservices.
Spring Boot is an opinionated way of building Java applications. Using Spring Boot, you can build web applications using Spring MVC as well as other technologies. Spring Boot provides a common set of components and opinions for building whatever application you are aiming at.
If I put my educator hat on, I would recommend starting with Spring Framework sans boot, only because it will help you understand what boot brings to the party. That being said, I never write traditional spring applications anymore, and always use Spring Boot. The speed to market proposition of Spring Boot is why it is the defecto way to build applications today in enterprise, but so much is done for you that if you really want to learn Spring, you will miss out.

I want to know what spring dependencies should I use on my website to make the work easy and spring or spring boot which one is better. also, suggest some frontend technologies that I can use to make the website smart.
It's a very broad question. And it all depends on what features you want in your web site. Just listing few basic module to give you some hints.
Spring MVC - For web application with MVC Pattern
Spring Security - To secure your app
Spring ORM - If using any ORM tool like hibernate
You need to explore more on the basis of your need.
Spring Boot vs Spring:
You should use Spring Boot if you are starting new project. Spring Boot came to make development process easier when using Spring Framework. In Spring, developer had to write lots of code to configure beans and dependencies. Spring Boot automated this process so that you no longer do it by yourself but Spring Boot will take care of it. Plus it provides some extra tools (In built Web Server, in Memory DB, tool to monitor and manage Spring Boot App )
Try to create a simple web app in Spring and Spring Boot to understand the difference.
Front-end Technologies:
JavaScript based framework/lib like Angular,React,Vue etc. are the trend for front-end now a days. Again there are pros and cons of each of them. Hence you need to evaluate, what suits you better as per your requirement.
As part of a new web application project, I'm planning to learn Spring. I started to read through the Spring framework reference. While I was googling, I came across Spring boot. What I understood is that spring boot helps to build application much faster than spring by reducing configuration. Now I'm little confused whether should I continue learning spring or jump to spring boot. My intention is to understand how spring works as a framework rather than a few features. So please let me know, as a beginner what should I do? First, learn Spring and then spring boot or vice-versa.
Update
Ok, I know it's a while since I asked this question. I kind of have an answer (personal one)
I started with Spring Boot and so far built one Spring Boot REST application. Yes, as others said, Spring Boot, helps you to get started quickly and being new to some language/technology, I would love to see a working module ASAP. So Spring boot helps you with that.
Later depending on your interest, you can start exploring in-depth how Spring boot does that magic.
So, in summary, go with Spring Boot and then deep dive to understand the underlying concept. Again this is my opinion.
Thanks, everyone for your inputs/suggestions.
If you want to develop web applications especially micro-services, I will recommend that you should learn Spring Boot first.
The first reason is that there are many resources and examples on
web, so you can easily find what you need.
The second reason is that Spring Framework (including Spring Boot) is
suitable for PaaS environment especially Pivotal. Therefore you can
rapidly deploy your applications without too much effort.
First of all, learn how Spring applications work.
Spring applications are based on the Object Relation Model. You need to understand the annotations and why we use them. Then you have to learn how Spring MVC works. Up to here, both Spring and Spring Boot are similar. Basically, Spring Boot is made so that a Spring-based application can be made very easily. Spring Boot is very good framework for the Web and other.
After learning the above things, then you can jump easily onto Spring Boot. However, if you jump directly to Spring Boot you will see there are many such things which are not described in the Spring Boot tutorials, since many of them expect that you have some prior knowledge of Spring.
So I'm about to learn Spring MVC. But what I don't understand is why should I use Spring MVC if I can implement the MVC pattern using a single servlet conroller and JSPs? What advantages does Spring MVC provide over simple java MVC pattern?
Actually yes, you can do it. Question is if you should do it. Spring MVC gives you better organization of your code.
Pure MVC Frameworks like Spring MVC are obsolete today. When combined with templating engines like Thymeleaf, it lacks functionality and developers usually reinvent JSF. For single-page apps based on some popular JS frameworks that need REST backend, JAX-RS is way cleaner and better than Spring MVC REST.
So no, today you don't need Spring MVC and can stick with pure Java EE. For simple, toy-like applications where servlets are enough, you don't really need it but it may be better to use it. For anything serious, MVC is outdated and Spring has nothing to offer.
Edit 2017: Spring offers JAX-RS integration. However, it has several pitfalls, for example Spring won't automatically register classes annotated with #Path for you. Details can be found in Dzone Article
The best way to realize that it's better to play with these technologies for yourself, if you want to try spring MVC I recommend you start with spring boot because you can create projects with more agility without configuring xml files
Spring Boot
Some Features
Create stand-alone Spring applications
Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
Provide opinionated 'starter' POMs to simplify your Maven configuration
Automatically configure Spring whenever possible
Provide production-ready features such as metrics, health checks and
externalized configuration
Absolutely no code generation and no requirement for XML configuration
One of the ideas applied in Spring (not invented by Spring) is
Do not reinvent a wheel.
Having a single controller is not a good idea I'd say - breaking separation of concerns principle.
You can learn more about MVC from Spring documentation.

Using JSF as view technology of Spring MVC
(3 answers)
Closed 6 years ago.
I am having a Project with J2EE that's not very big , i began using JSF and i found it very nice and easy , but by the time i was searching on the internet i found a integration called JSF and SpringMVC , so i am wondering is that a better way to develop application and is it recomanded for me to use it or i'll be doing fine with jsf all alone.
i saw this link
http://www.mkyong.com/jsf2/jsf-2-0-spring-integration-example/
Both JSF and SpringMVC are implementations of the MVC pattern, so using both framework together is not the best design approach. JSF is a component based framework but SpringMVC is a request based. However you can use both together to get benefit of the SpringSecuirty framework if you need security features in your applications. Another advantage from my point of view is you can use Spring IoC features without the need to use EJB and run your application in a normal web container like tomcat.
Finally, it's your decision based on your requirements.
That tutorial is talking about spring+JSF and not springMVC+JSF.
If you don't know anything about spring you should be doing fine JSF all alone.
There is no a better way nor a worse, they are just showing how you can integrate spring with jsf.
I know java well, and have some experience in EclipseLink, Hibernate, JSF, Grails and some other stuff. but now I wanna learn Spring MVC for web apps and maybe for the sites. and should I learn Spring Framework before begin Spring MVC, or not?
In short, yes. Spring MVC borrows a lot of concepts like dependency injection from Spring, so you need to burn these concepts in before learning Spring MVC. For example, just create a simple Java project, create a few beans, understand the concepts of how a container / injection / wiring work, and then move on to implementing them in Spring MVC.
The most obvious benifit is you can integrate Spring with other web frameworks that you might already be familiar with. That way you get the best of both worlds, and don't have to learn Spring MVC until you have to.
This tutorial explains connecting to a database the spring way, and explains basic Spring concepts while at it. You could then follow it up with the Spring MVC tutorial.
Spring has an easy learning curve, (not to master it of course) so I would suggest learning them together on a small-scale test project.
I don't know if the question is pertinent for stackoverflow, but in any case I think learning Spring MVC is the best way to take a first step to learn Spring, in fact many Spring tutorials start with a Spring MVC application.
