How beans are created in spring?

Bean life cycle is managed by the spring container. When we run the program then, first of all, the spring container gets started. After that, the container creates the instance of a bean as per the request, and then dependencies are injected. And finally, the bean is destroyed when the spring container is closed.

What is a bean in spring?

A bean is an object that is instantiated, assembled, and otherwise managed by a Spring Io, and c container. These beans are created with the configuration metadata that you supply to the container. For example, in the form of XML definitions which you have already seen in the previous chapters.

And finally, the bean is destroyed when the spring container is closed. Therefore, if we want to execute some code on the bean instantiation and just after closing the spring container, then we can write that code inside the custom init () method and the destroy () method. The following image shows the process flow of the bean life cycle.

Where do beans come from?

Beans were an important source of protein throughout Old and New World history, and still are today.

Probably originating from South America, common beans were unknown in Europe until introduced by early Spanish explorers in the 1500s. They found these beige beans mottled with darker brown widely used as food, and called them painted, or pinto beans.
