Hi Friend when you going start learn Spring Framework you will start to write first Hello World Program
Below is step by step to write first program
1. Write the applicationContext.xml (bean container)
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-2.5.xsd"
xmlns:context="http://www.springframework.org/schema/context">
<context:annotation-config/>
<context:component-scan base-package="com.dao"></context:component-scan>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
<bean id="cal" class="com.test.calculation" init-method="init">
<property name="name" value="kumud"></property>
</bean>
</beans>
2. Write bean class for calculation
package com.test;
import org.springframework.beans.factory.BeanNameAware;
public class calculation implements BeanNameAware{
public String name = null;
public String getName() {
return this.name;
}
public void init() {
System.out.println("Inside the init methos");
}
public void setName(String name) {
this.name = name;
}
public void setBeanName(String arg0) {
System.out.println("setting the bean name ********************");
}
}
3. write TestClass
package com.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestClass {
public static void main(String [] args)
{
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
calculation calc=(calculation)ctx.getBean("cal");
System.out.println("The name of is"+calc.getName());
}
}

System.out.println("The name of is"+calc.getName());
}
