  Slide 2 www.edureka.co/spring-framework Atthe end of this module, you will be able to understand: Objectives Introduction to Spring and its Architecture Dependency Injection Spring MVC Architecture Exception Handling With Spring MVC Build a Web Application using Spring
• 3.
  Slide 3 www.edureka.co/spring-framework InJava technology there are many frameworks that helps the programmers to easily build complex applications You can choose these frameworks for building your applications Example: » Hibernate  Database access mechanism » Struts  Web Layer » EJBs  Services like transactions, security & messaging » Log4J  Logging Java Frameworks!!!
• 4.
  Slide 4 www.edureka.co/spring-framework Problem: »Applications that use the varied frameworks and services are difficult to maintain as they grow Need: » Applications that use a number of frameworks and services have to remain maintainable » Codes should be loosely coupled with the frameworks so that testing and reusability becomes easy Java Frameworks!!!
• 5.
  Slide 5 www.edureka.co/spring-framework SpringFramework provides a light-weight solution to develop maintainable and reusable enterprise applications It provides very simple and rich facilities to integrate various frameworks, technologies and services in the application Spring Framework!!!

  Slide 8 www.edureka.co/spring-framework Objectscreated by the container are also called managed objects or beans The container can be configured by loading XML files or detecting specific Java annotations on configuration classes Central to the Spring Framework is its inversion of control (IoC) container, which provides a consistent means of configuring and managing Java objects The container is responsible for managing object lifecycles of specific objects: creating these objects, calling their initialization methods, and configuring these objects by wiring them together Dependency Injection
• 9.
  Slide 9 www.edureka.co/spring-framework Thereare two ways to perform Dependency Injection : Setter Method Dependency Injection(DI) - In this type of DI the required bean is injected through setter method for that bean Constructor Dependency Injection(DI) - In this type of DI the required bean is injected through the constructor argument Types of Dependency Injection

  Slide 10 www.edureka.co/spring-framework Model-View-Controllerarchitecture is used for interactive web-applications. This model minimizes the coupling between business logic and data presentation to web user. This model divides the web based application into three layers: » Model: Model domain contains the business logics and functions that manipulate the business data. It provides updated information to view domain and also gives response to a query. And the controller can access the functionality which is encapsulated in the model » View: View is responsible for presentation aspect of application according to the model data and also responsible to forward query response to the controller » Controller: Controller accepts and intercepts user requests and controls the business objects to fulfil these requests. An application has one controller for related functionality. Controller can also be depends on the type of clients Model-View-Controller (MVC)

  Slide 13 www.edureka.co/spring-framework SettingUp Spring MVC
• 14.
  Slide 14 www.edureka.co/spring-framework SpringMVC provides a great way to handle exceptions and errors @ExceptionHandler annotation is core to this feature For each Spring controller we can simply define a method that automatically gets called if a given exception occurs So any error resulting in ClassNotFoundException will lead to classNotFoundError.jsp page rather than displaying the error logs to user. Exception Handling with Spring MVC
• 15.
  Slide 15 www.edureka.co/spring-framework Oneof the shortcomings of @ExceptionHandler is it only handles exception getting raised from the controller where it is defined. It will not handle exceptions getting raised from other controllers Now this will take care of ClassNotFoundException thrown from any controller and will show classNotFoundError.jsp page @ControllerAdvice
