Writing Maven Dependency for javax.persistence
  • Dependency injection and inversion of control - Setter and Constructor Injection (Loose Coupling)
  • IOC container - Beanfactory, Application context.
  • LifeCycle
  • Auto Wiring - no, byName, byType, constructor, autodetect
  • Scope
  • Configuration file - It’s an xml file where the classes are defined to create the object for it in an spring container.
  • Configure Spring Bean - XML configuration, Java based configuration, Annotation based configuration.
  • Bean - Spring bean, Java bean, Inner beans
  • Components
  • Dispatcherservlet & ContextLoaderListener
  • Handler mapping - It defines mapping between URL requests and Handler objects.
  • Controller - Front Controller, Simple Form Controller, Abstract Controller, Parameterizable View Controller, Multi Action Controller
  • Model and View object
  • View resolver
  • Lombok
  • Qualifier
  • Session - Cookies, URL rewriting, HttpSession, Hidden form fields
  • Load on startup
  • Multipartresolver - This interface is used for uploading files. CommonMultipartResolver and StandardServletMultipartResolver.
  • Exception-handling - Controller based, Global Exception handler, HandlerExceptionResolver
  • Transaction management
  • RowCallbackHandler
