Spring with xml configuration file

February 15, 2018

In this example, we will see how you make dependency with the XML configuration file. First I am going to create the class Car withe dependancy Engine .
So your Car class would be like this

package com.kayak;

public class Car {

    Engine engine;
    private String name;

    public Car() {


    public String getName() {
        return name;

    public void setName(String name) {
        this.name = name;

    public void setEngine(Engine engine) {
        System.out.println("Inside setEngine()");
        this.engine = engine;

    Car(Engine engine) {
        System.out.println("Inside Car Constrsctor");
        this.engine = engine;


This is the dependant class Engine

package com.kayak;

public class Engine {
        System.out.println("Engine Created");

Next you can create the configuration file bean.xml



When you look at the XML file you can see the I have created the withe ref which points to bean having the id with engine. So we tell to spring that Engine is dependant class of the Car class

Now we can create the bean using context

package springstrat;

import com.kayak.Car;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringStrat {

    public static void main(String[] args) {
        ApplicationContext ctx = new  ClassPathXmlApplicationContext("bean.xml");
        Car car=(Car)ctx.getBean("car");

When you run the application you can see the following output

Feb 15, 2018 5:09:58 PM org.springframework.context.support.ClassPathXmlApplicationContext prepareRefresh
INFO: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@3d646c37: startup date [Thu Feb 15 17:09:58 IST 2018]; root of context hierarchy
Feb 15, 2018 5:09:58 PM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions

Alternatively, you can use the followng configuration file
