I want to develop a project using with JSF, Spring, Hibernate technologies. I don't know how my project structure should be. Interfaces, implements, managedBeans, models, services, dao and goes on.
Is it possible you to guide me about this?
Thanks.
This JSF + Spring + Hibernate might be useful for you. Just follow all the procedures correctly and you will get what you want. Before I had tried it before. Or just download it's Source Code which you can find at the bottom.

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 For anything serious, MVC is outdated and Spring has nothing to offer.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.
I'm planning to start learning Spring but when I open any spring tutorial, I find many modules like Spring REST, spring MVC etc.
I'm really confused on how to start with spring, from which module to start, how are these modules related to each other, should I go through all the modules??
I tried searching many sites to answer my questions but couldn't find satisfactory ans, so thought of posting here. It would be great if somebody can guide me in this regard.
Spring is a java framework which provides solutions to several problems. So i guess it really depends on what you are planning to learn. The most important to learn first is understanding what Dependency Injection and inversion of control means. When you understand this you will understand why the rest of the frameworks are designed as it is. i suppose learn Spring IoC first since this is basically the core component of Spring Framework. Link: http://docs.spring.io/spring-framework/docs/current/spring-framework-reference/html/beans.html
After learning Spring IoC, you can go on learning each specific Spring frameworks which address specific problems. For example:
Are you interested in Web development? --> Spring MVC
Are you interested in storing data to database? --> Spring Data
Are you interested in developing web services / web apis --> Spring REST
http://docs.spring.io/spring-framework/docs/current/spring-framework-reference/html/overview.html
Start with Spring Core Module, which is the heart of entire Spring.
Spring Core Module helps in Injecting Dependencies (java objects) into
the Application at Runtime.

A good knowledge of design patterns is essential for learning any framework in Java.
These Youtube videos can give you a good understanding of basic Spring.
As explained in the previous answers, start learning with the Spring core. You need to have a sound knowledge of servlets, JSP, Hibernate (ORM's) to understand the advanced topics.
I am a newbie in web development. I'm using servlets and JSP for web development.However, I've learnt lately that Spring Framework is apt for that which incorporate servlets, jsp etc. So, my question is that can I now run my program using Spring framework ? Like, I have 2 jsp codes, and 1 servlet class. So, how can I migrate the code in Spring Framework ? what additional things or codes do I need to maintain ?
Migrating an existing J2EE project is easy.
You will get rid of a lot of "boilerplate" code in the process. The easiest way to do it in my opinion will be to use SpringToolSuite.
Import your project in STS and then add "Maven" nature to it. In the pom configuration you can edit all the jars that you need and mention the spring framework. Once all this is setup it will be just a matter of minutes to change the code if it is small.
You can follow these video tutorials about maven and spring to learn about it.
JavaBrains
There are more tutorials by "New Circle training" on youtube for the same.
I would also recommend you to read Spring in action 3rd edition-Manning
This book is a must and the best way to learn spring framework. Hope this helps
I want to learn how to create maven project which handles Spring Data JPA and JSF. I tried to find a lot for simple examples but I could not. Can anybody please help me out? I am using Eclipse as a development platform.
They are technologies in opposite ends of the stack.
Learn basics of Spring Data from Petri
Learn basics of JSF here by MKYong
Both use maven.
For additional JSF resources, use for instance this as offset.
I am new to Spring. Just having basic understanding of it.
I am curious to know, can we use Spring MVC Framework and other components of Spring framework (like AOP) together?
Thanks!
Briefly yes.

Spring could potentially be a one-stop shop for all your enterprise applications, however, Spring is modular, allowing you to pick and choose which modules are applicable to you, without having to bring in the rest. You can read details about modules available in Spring Framework.Here
