I would like to give elaborated Idea on Spring ApplicationContext and
BeanFactory
BeanFactory
BeanFactory can handle all Beans and gives instantiated Object as and when
client requests .
in this way BeanFactory Reduces the Burden
BenaFactory calls customized bean Lifecycle clas Interfaces suchas
InitializingBean and DisposableBean
ApplicationContext
- ApplicationContext is resolves All text messages by loading i18N Support
- It supports generic way of loading Images
- It Supports Event machanism for which listeners beans have been
registered
- BeanFactory Supprots Programatic way of loading mechanism but application
Context supports declarative way of loading beans
-ApplicationContext itself is resources loader for loading different
resources and files
- MessageResource is another interface which is used to load and resolve
LocalizedMessages by implementing this interface and this is pluggable
Spring Bean Inheritance
Property Inheritance :
This is to inherit the properties from super class to child class
Collection Inheritance
This is used to get super class collections into child class collections
for which u have to set attribute at bean level hich is merged="true"
if u want different collection to be copied to child class collection then
u have to defin a property that is default-merge="true"
Spring Bean WebApplictionContext
This provides following fecilties
Controllers: these are C part of MVC architecture
HandlerMappings : handle the execution of a list of pre and post processors
ViewResolvers : Capable of resolving view names to views
Local Resolver : for resolving Loca,les
ThemeResolvers: for Resolving Themes
Controllers:
AbstractController :
handleRequestInternal()
MultiActionController:
delegate
methodNameResolver
ParameterMethodNameResolver
InternalPathMethodNameResolver
PropertiesMethodNameResolver
CommandControllers:
These are nothing nut ActionForm in struts
AbstractCommandController
AbstractFormController
SimpleFormController
SimpleWizardFormController
HandlerMappings:
SimpleUrlHandlerMapping
BeanNameUrlHandlerMapping
Here Interceptors Can be introduced
Interceptor :
HandleInterceptorAdapter
ViewResolver:
XmlViewResolver
InternalResourceViewResolver
UrlBasedViewResolver
ResourceBundleViewResolver
