5. Spring Config bean via XML (Advanced)

1. Set the scope of the bean

When you create a bean instance from a Spring IOC container, you can not only instantiate the bean, but also specify a specific scope for the bean, and Spring supports the following 5 scopes:

1. Singleton: Single case mode. In the entire IOC container, the bean instance defined with Singleton will have only one.

2. Prototype: Prototype mode, each time a prototype defined bean is obtained through the container's Getbean method, a new bean instance is generated

3. Request: For each HTTP request, the bean defined with the request will produce a new instance, that is, each HTTP request will produce a different bean instance. The scope is valid only if you are using spring in a web app

4.session: For each HTTP session, a new instance is generated using bean Soymilk defined by session. The scope is also valid only if spring is used in the Web App
