Spring Inversion of Control (IoC) also known as Dependency Injection (DI) is a process by which objects define their dependencies with collaborating objects. Singleton scoped bean permits a single bean definition to a single object instance per Spring IoC container. It is the default scope of Spring IoC container.

    System.out.println("Initializing ApplicationContext");
    ApplicationContext factory = new ClassPathXmlApplicationContext("singleton.xml");
    System.out.println("ApplicationContext Initialized");
    System.out.println("Accessing first bean");
    SimpleBean first = (SimpleBeanfactory.getBean("first");

    first = (SimpleBeanfactory.getBean("first");

    System.out.println("Accessing second bean");
    SimpleBean second = (SimpleBeanfactory.getBean("second");

    second = (SimpleBeanfactory.getBean("second");


It gives the following output,
Initializing ApplicationContext
ApplicationContext Initialized
