Spring 3 Hello World...

Download Spring 3.1 from here. 

Once you extract, create a user library named Spring3 and include all the jars from spring-framework-3.1.0.M2\dist directory. Add one more jar(commons-logging.jar) that you can find in spring-framework-3.1.0.M2\projects\spring-build\lib\ivy directory.





 Create 2 classes as follows.

package com.test;
public class HelloWorld {

    public void printHello(){
        System.out.println("Hello Spring 3.0!");
    }
}

And

package com.test;

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

public class HelloWorldTest {

    public static void main(String[] args) {
        //XmlBeanFactory ctx = new XmlBeanFactory(new ClassPathResource("hello.xml"));  //Deprecated Approach
        ApplicationContext ctx = new ClassPathXmlApplicationContext("hello.xml");
        HelloWorld hw = (HelloWorld) ctx.getBean("HelloBean");
        hw.printHello();
    }
}

Now, create an xml file hello.xml in src directory.





 

That's it.
