Building Web App Using Spring MVC, Hibernate, Bootstrap, and REST Services

Why Spring ?

Goals of Spring:

• Light weight Development Model with support of java POJOs -   To make simpler of EJBs.
• Loose coupling using Dependency Injection.  -   with the help of annotations and configurations, springs offer loose coupling features.
• Declarative Programming  -  In the support of Aspect oriented programming - which basically allows to add application's wide services.
• Reduce Boilerplate Code -   Huge code reduction in the essence of utility classes.

Spring Architecture :

 1)  Core Container : Contains below modules.

           Core   & Beans Modules                  - Inversion of Control, and  Dependency Injection.  It
                                                                        provides bean factory to assist with beans.  It avoid
                                                                        programmatic singletons.

          Context                                              -   On top of core bean's module - which is to lookup
                                                                         objects which is in like   similar to  JNDI registry.  It
                                                                          inherits from beans module and supports
                                                                          Internationalization,  event propagation, resource
                                                                          loading etc.

            Expression Language                    :       Powerful for querying and manipulating object
                                                                           graph at run time.  It's extension to  Expression
                                                                           Language  from JSP2.1 .  This language supports for
                                                                          setting and getting the properties values, method
                                                                          invocation, accessing the context of arrays, collections
                                                                           and retrieval of objects binding from spring moc
                                                                           container.

2)  Data Access / Integration  :

               JDBS       -  Built in JDBC infrastructure, helps to remove tedious JDBC codings, and
                                   parsing vendor specific error codes.
              ORM         -  Integration layer for popular Object Relational Mappings  APIs, JDO,
                                    Hibernate and I practice etc.
               OXM        -   Provides abstractions to support object/XML mappings , JAXB, JSTL etc.
              JMS           -   For Producing and consuming Messages for MOM based applications.          
            TRANSACTIONS   -  Programatic and declarative programming

3)  Web

           Web Sockets    -
           Web Servlets    -  Initialization of IOC container
            Web Structs     -   Support for classes integrating with structs and
            Web Portlet     -   Portlet environments



4)  Aspect Oriented Programming   :

                           Logging, security, AspectJ.

5)  Test



Prerequisites  for   Spring environment setup :
