Solution: The GroovyObjectCustomizer interface is a callback that allows you to hook additional creation logic into the process of creating a Groovy-backed bean.

Solution: Spring creates a JDK dynamic proxy implementing all of the interfaces that are specified in the ‘script-interfaces’.

Solution: There is just one (small) thing that you need to be aware of when advising scripted beans. You cannot use class-based proxies, you must use interface-based proxies.

Solution: The scope attribute on the various lang:language/ elements allows you to control the scope of the underlying scripted bean, just as it does with a regular bean.

Solution: All of these libraries are available in the Spring-with-dependencies distribution of Spring (in addition to also being freely available on the web).

Solution: Spring is able to refresh a scripted bean definition from its source once you have specified the checking interval in the refresh-check-delay attribute.

Solution: When a method is called on that bean, Spring will check the script source if the specified checking interval has elapsed. The Spring will refresh the bean definition from the script source if it has been changed.

Solution: By default, the refresh-check-delay attribute is negative, so the refresh checking feature is disabled. You can assign the milliseconds for refresh checking in this attribute to enable this feature.

Solution: You can define an inline script source in the lang:inline-script element of a scripted bean to replace a reference to an external script source file by the script-source attribute.

Solution: Spring IoC container only loads the bean configuration once, at startup.
