  1. Design & Development of Web Applications using Spring MVC by Naresh Chintalcheru
  2. Spring MVC Another Web MVC Framework?
  3. Spring MVC Another Web MVC Framework? After learning Struts, JSF, DDUI ……. …………….. now Spring MVC ?
  4. Spring MVC ● Benefit of using a Web Framework ● Removes the need of boilerplate code ● Gather HTTP Request Parameters ● Validation & Conversions ● Update the Model ● Standard code level design for multiple applications in an enterprise ● Navigation Flow ● Validations
  5. Spring MVC ● Benefit of using a Web Framework ● No Web Application Component Design ● Use Web Framework as Design Templates and plugin the View, Model and Controllers
  6. Spring MVC ● Benefit of using a Web Framework ● Speed up the development
  7. Spring MVC Web MVC Frameworks ● Struts ● JSF ● Wicket ● DDUI ● Spring MVC
  8. Spring MVC Presentation Layer Frameworks ● Web MVC Framework ● Template Framework ● View Technologies ● UI Widget Framework
  9. Spring MVC Template Frameworks ● Tiles ● Facelets ● SiteMesh View Technologies ● JSP ● XHTML ● XSLT UI Widget Frameworks ● JQuery ● DOJO ● SFX
  10. Spring MVC Why Spring MVC Framework?
  11. Spring MVC Spring MVC is a action-based or request-based framework similar to Struts. JSF is a component-based framework.
  12. Spring MVC
  13. Spring MVC
  14. Spring MVC Spring MVC vs JSF ● JSF is part of JEE Specification ● JSF is based on component architecture and has learning curve ● Limited HTTP GET method support in JSF ● REST Web Services Support in Spring MVC.
  15. Spring MVC Spring MVC vs Struts ● Struts forces concrete Inheritance of Action/ActionForm, taking away single shot of Inheritance in Java. ● Spring MVC based on Interfaces and Annotations. ● Spring MVC is truly view-agnostic. Many options in View Technologies. ● Use Spring IoC Container from Presentation Tier to Integration Tier.
  16. Spring MVC Spring MVC is only one module in the Spring Framework
  17. Spring Framework Fundamentals
  18. Spring Framework Fundamentals
  19. Spring Framework Fundamentals What is Spring Framework ? ● Spring Framework is ….. ● Open Source Meta Framework ● Provides frameworks and container ● Simplify the development
  20. Spring Framework Fundamentals Spring framework is a Layered Architecture Choose the modules needed and eliminate other modules All modules are built on the top of its core container
  21. Spring Framework Benefits: ● Light Weight ● Promotes good OO design ● Container Agnostic Framework : Insulates the application from its hosting container.
  22. Spring Framework Fundamentals Spring Has Two Web Frameworks ● Spring MVC ● Spring Web Flow
  23. Spring Framework Fundamentals Spring Framework Web Flow ● Secondary Page Flow logic framework ● Can be used with Spring MVC, JSF and Struts.
  24. Spring Framework Fundamentals Spring MVC Request Flow ….
  25. Spring MVC Spring MVC
  26. Spring MVC Spring MVC
  27. Spring MVC Front Controller Design Pattern: ● DispatcherServlet is the Front Controller handles Client Requests. ● ActionServlet in Struts ● FacesServlet in JSF ● AppServlet in DDUI
  28. Spring MVC Controller Design Pattern in MVC: ● Controllers are components that are being called by the Dispatcher Servlet for performing page level logic and delegate to Service Objects. ● Action Classes in Struts ● Managed Beans & Backed Beans in JSF ● PageProcessor in DDUI
  29. Spring MVC View Resolver & Navigation Logic: ● Resolves view names to views. Resolves navigation logic from spring-mvc.xml ● Struts-config.xml in Struts ● Jsf-config.xml in JSF
  30. Spring MVC Developing App using Spring MVC: ● Step 1: web.xml : Front Controller <web-app version="2.4"> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.*</url-pattern> </servlet-mapping> </web-app>
  31. Spring MVC Developing App using Spring MVC: ● Step 2: web.xml : ApplicationContext <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-mvc.xml</param-value> </context-param>
  32. Spring MVC Developing App using Spring MVC: ● Step 3: spring-mvc.xml : Component Scan <beans> <context:component-scan base-package=“com.sf.web"/> </beans>
  33. Spring MVC Developing App using Spring MVC: ● Step 4: Controller Classes @Controller public class EmployeeController { @Autowired private final EmployeeSO employeeSO; @RequestMapping("/emplist") public String empHandler(Model model) { List empList = employeeSO.getAllEmp(); model.addAttribute(“empList”, empList); return “ListEmpPage” ; } }
  34. Spring MVC Bean Validation Framework JSR-303: public class Employee { @NotNull @Pattern(regexp = "[a-z-A-Z]*") private String firstName; @Size(min=2, max=15) private String lastName; @Past private Date birthDate; @Email (message=“Invalid Email “) private String email;
  35. Spring MVC REST Web Services: http://localhost:8080/SpringMVC/employee/John @Controller @RequestMapping("/employee") public class EmployeeController { @RequestMapping( value="/{name}“ ) public String getEmp(@PathVariable String name, ModelMap model) { model.addAttribute(“emp", name); return “EmpListPage"; } }
  36. Spring MVC Question & Answers
