Spring framework download and integration with eclipse step by step.

In this tutorial we will learn how we can download spring framework jars for eclipse and integrate the downloaded spring framework with eclipse . Then we create a basic Spring example to check our setup is successful or not.

Here are the steps to configure Spring core with eclipse IDE

1. Install JDK and eclipse
2. create a java project in eclipse called SpringTest
3. create a folder  lib under SpringTest\lib
4. Download commonLoggin1.2.jar from here http://commons.apache.org/proper/commons-logging/download_logging.cgi

5. extract it and put jars into lib folder earlier created.
6. Download spring from here
http://repo.spring.io/release/org/springframework/spring/4.1.6.RELEASE/
7. extract it and put all jars into the lib folder .
8. Right click on SpringTest ->properties->java build path
9. click on add external   jar and add all jars under lib folder
10.  Create a  folder called configFiles under SpringTest/ src folder.
11. create beans.xml file in configFiles

Add following lines

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

   <bean id="helloWorld" class="com.example.HelloWorld">
       <property name="greet" value="Hello World! Welcome to Spring"/>
   </bean>

</beans>

12 Create a package com.example under
SpringTest\src

13. create a java file HelloWorld.java under the package
com.example

14. Write following in HelloWorld


package com.example;

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

public class HelloWorld {
   
    private String greet;

    public String getGreet() {
        return greet;
    }

    public void setGreet(String greet) {
        this.greet = greet;
    }
   
   
    public static void main(String[] args) {
       
        ApplicationContext ctx = new ClassPathXmlApplicationContext("configFiles/beans.xml");
       
        HelloWorld bean =(HelloWorld) ctx.getBean("helloWorld");
        System.out.println(bean.getGreet());
       
       
    }
   
   

}

15. Run as java application output will be
Hello World! Welcome to Spring
