Well the core of the Spring Framework is its Inversion of Control (Ioc) container.

The IoC container manages java objects – from instantiation to destruction – through its BeanFactory.

Java variants that are contained by the IoC container are known beans, and the IoC container settles a bean's scope, lifecycle events, and any AOP variants for which it has been managed and coded.

A Spring bean in the IoC container can typically be any POJO (plain old java object).

POJOs in this context are defined simply as reusable modular components –

Example 1. DefaultMessage


public class DefaultMessage {

private String message = "Spring is fun.";

/**
* Gets message.
*/
public String getMessage() {
return message;
}

/**
* Sets message.
*/
public void setMessage(String message) {
this.message = message;
}

}

If the container instincts the message bean, it is equal to initializing an object in your code with new DefaultMessage()
