Spring 3.0 Hello World Example

Here I am posting my first very basic example on a very famous Java framework called Spring.

We need following requirements:-

1.Spring 3.0

2.Eclipse

3.JDK 1.6

5 Steps to create Hello World Example in Spring 3.0

 

1.First create a Java Project in Eclipse:

2.Include the Spring 3.0 jar in Project:

          Right Click on Project Then Goto

          Build Path->Configure Build Path

Then give the path of the jars where you have put it.

3.Create HelloWorld Class:

package com.tutorialjam.tutorial.beans;

public class HelloWorld {
 
 private String guestName;

 public void setGuestName(String guestName) 
 {
  this.guestName = guestName;
 }
 
 public String sayHello()
 {
  return "Hello "+guestName+"!!!";
 }

}

4.Create a xml file in root folder that includes:

5.Create A class that has main() method:

package com.tutorialjam.tutorial.app;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.tutorialjam.tutorial.beans.HelloWorld;

public class Main {

 /**
  * @param args
  */
 public static void main(String[] args) {
  
  ApplicationContext context= new ClassPathXmlApplicationContext("beans.xml");
  HelloWorld hello= (HelloWorld) context.getBean("helloworld");
  System.out.println(hello.sayHello());

 }

}

 

Here your first Spring application ready to run.You can run the main method and see output. Thanks.
