Spring: Application Context

This Session Talks about the Flavors of Application Context,

• ClassPathXmlApplicationContext : Loads Context Definition From XML File Located in Classpath
• ApplicationContext context=new
  ClassPathXmlApplicationContext("bean.xml");
  
• FileSystemXmlApplicationContext : Loads from an xml loacted in filesystem (absolute/relative path should must be mentioned)
• ApplicationContext context=new
  FileSystemXmlApplicationContext("c:/bean.xml");
  
• XmlWebApplicationContext : Loads From xml file existing with in web application context.
• ApplicationContext context=new
  XmlWebApplicationContex("bean.xml");
  
• Consider Following xml Bean definition,
  
• <bean name="hello" class="org.srinidhi.beans.Helloworld">
• getBean() method of context will actually get the instantiated object of Helloworld,
  public static  void main(String args[]){
  
  ApplicationContext context = new FileSystemXmlApplicationContext("c:/bean.xml");
  
  Helloworld hw = (Helloworld ) context .getBean("hello"); 
  
  hw.sayHello();             // Calling method of Helloworld Class.
  
  }
  
  Hope You like this session.
