By Arvind Rai, August 15, 2013

1. Access application components
2. Loads resources
3. Publishes events to registered listeners
4. Resolves messages for internationalization (i18)
ApplicationContext can be used like

ApplicationContext context = new ClassPathXmlApplicationContext("spring-app.xml");

Find the example below to use ApplicationContext.

SpringDemo.java

package com.concretepage;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringDemo {
    public static void main(String... args) {
    	ApplicationContext context = new ClassPathXmlApplicationContext("spring-app.xml");
    	Entitlement ent=(Entitlement) context.getBean("entitlement");
         System.out.println(ent.getName());
    } 
}

spring-app.xml

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
    <bean id="entitlement" class="com.concretepage.Entitlement">
	    <constructor-arg name="name" value="Entitlement"/>
	    <constructor-arg name="time" value="20"/>	           
    </bean>
</beans>

Entitlement.java

package com.concretepage;
public class Entitlement {
	private String name;
	private int time;
	public Entitlement(String name,int time){
		this.name=name;
		this.time=time;
