What is a Spring Bean

A "Spring Bean" is simply a Java object.

When Java objects are created by the Spring Container, then Spring refers to them as "Spring Beans".

Spring Beans are created from normal Java classes .... just like Java objects.

Here's a blurb from the Spring Reference Manual

In the early days, there was a term called "Java Beans". Spring Beans have a similar concept but Spring Beans do not follow all of the rigorous requirements of Java Beans.

In summary, whenever you see "Spring Bean", just think Java object. :-)
