How do you define a bean scope?

To define a bean scope in Spring, you specify the lifecycle and visibility of a bean within the application contexts it is used. The Spring framework supports several scopes, but the most commonly used are singleton and prototype. Additionally, there are web-aware scopes like request, session, application, and websocket.

Here's how you can define a bean scope:

1. Annotation-based Configuration: You can use the @Scope annotation on the bean definition to specify its scope. For example, to define a singleton scope (which is the default), you can use @Scope("singleton") or simply omit the scope as singleton is the default. For a prototype scope, you would use @Scope("prototype").

   java Copy

   @Component
   @Scope("prototype")
   public class MyPrototypeBean {
       // class body
   }

2. Java-based Configuration: When using Java configuration, you can use the @Bean annotation along with @Scope in a configuration class.

   java Copy

   @Configuration
   public class AppConfig {
       @Bean
       @Scope("singleton") // This is optional as singleton is the default scope
       public MySingletonBean mySingletonBean() {
           return new MySingletonBean();
       }
   
       @Bean
       @Scope("prototype")
       public MyPrototypeBean myPrototypeBean() {
           return new MyPrototypeBean();
       }
   }

3. XML-based Configuration: In XML conf...
