The Spring Framework supports six scopes for beans:

• Singleton
• Prototype
• Request
• Session
• Global session
• Custom

The default scope is singleton. In this scope, a single instance of the bean is created and shared by all consumers. This is the most common scope to use for beans that are not thread-safe.

The prototype scope creates a new instance of the bean for each consumer. This is useful for beans that are thread-safe or that need to be independent of each other.

The request scope creates a new instance of the bean for each HTTP request. This is useful for beans that are only needed for the duration of a request.

The session scope creates a new instance of the bean for each HTTP session. This is useful for beans that need to be associated with a particular user session.

The global session scope is similar to the session scope, but it is only available in a portlet environment.

The custom scope allows you to define your own scope. This can be useful for beans that require a specific lifecycle.

To set the scope of a bean, you can use the @Scope annotation. For example, the following annotation defines a bean with the prototype scope:

@Scope(value = "prototype")
public class MyBean {
...
}

You can also set the scope of a bean in XML configuration. For example, the following XML snippet defines a bean with the singleton scope:

<bean id="myBean" class="com.example.MyBean" scope="singleton">
...
</bean>
