Spring @Qualifier Annotation

The @Qualifier annotation is accompanied with @Autowired to figure out which bean you want to wire.

First create a new Java Project and configure it as Maven Project. For Reference, Click Here

Add the following dependencies in pom.xml





Now create Employee Class as following.

package com.kruders.bean;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;

public class Employee {
	private String name;
	private Address address;
	public Employee() {
	public Employee(Address address) {
		this.address = address;
	public String getName() {
		return name;
	public void setName(String name) {
		this.name = name;
	public Address getAddress() {
		return address;
	public void setAddress(Address address) {
		this.address = address;

Now create Address Class as following

package com.kruders.bean;

public class Address {
	private String city;
	private String country;
	public String getCity() {
		return city;
	public void setCity(String city) {
		this.city = city;
	public String getCountry() {
		return country;
	public void setCountry(String country) {
		this.country = country;

2. Configuration

Create Spring-Bean.xml and write the following code

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="employee" class="com.kruders.bean.Employee">
        <property name="name" value="Puneet" />
    <bean id="address1" class="com.kruders.bean.Address">
        <property name="city" value="Delhi" />
        <property name="country" value="India" />
    <bean id="address2" class="com.kruders.bean.Address">
        <property name="city" value="Delhi" />
        <property name="country" value="India" />

3. Run Program

Create Main.java class that displays the employee and address details and run it as Java Application

package com.kruders.core;

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

import com.kruders.bean.Employee;

public class Main {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext(
		Employee employee = (Employee) context.getBean("employee");

		System.out.println("Name " + employee.getName());
		System.out.println("City " + employee.getAddress().getCity());
		System.out.println("State " + employee.getAddress().getCountry());


When you run the above example you’ll get an output like:

Name Puneet
City Delhi
State India

The folder structure of the example is shown below in Figure 29.1
