Here we are going to explore about spring provided Static Factory Method Instantiation to know how we can work with Static Factory Method Instantiation in our projects.

Lets see the example:
Technologies used :-
1) java (1.8).
2) maven (3.5.2).
3) Spring (4.0.0).

Project Structure

Execute below command for creating maven project.
mvn archetype:generate -DgroupId=com.sjg

Below is the maven project structure with packages and java src files.

package com.sjg.beans;

import java.util.Calendar;

public class Alarm {
    private Calendar calendar;

    public void sayTime() {

    public void setCalendar(Calendar calendar) {
        this.calendar = calendar;

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

    <bean id="alarm" class="com.sjg.beans.Alarm">
        <property name="calendar" ref="calendar" />
    <bean id="calendar" class="java.util.Calendar" factory-method="getInstance" />

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

<project xmlns=""; xmlns:xsi="";

package com.sjg.test;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import com.sjg.beans.Alarm;

public class Test {
    public static void main(String[] args) {
        BeanFactory factory = new XmlBeanFactory(new ClassPathResource("com/sjg/common/application-context.xml"));
        Alarm alarm = factory.getBean("alarm", Alarm.class);
