java.lang.Object org.springframework.web.context.support.ServletContextFactoryBean
Simple FactoryBean that exposes the ServletContext for bean references. Can be used as alternative to implementing ServletContextAware, allowing to pass in the ServletContext to a constructor argument or any custom bean property.
Note that there's a special FactoryBean for exposing a specific ServletContext attribute, named ServletContextAttributeFactoryBean. So if all you need from the ServletContext is access to a specific attribute, ServletContextAttributeFactoryBean allows you to expose a constructor argument or bean property of the attribute type, which is a preferable to a dependency on the full ServletContext.

public void setServletContext(ServletContext servletContext)
ServletContextAware
Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.

FactoryBean
If this method returns null, the factory will consider the FactoryBean as not fully initialized and throw a corresponding FactoryBeanNotInitializedException.

FactoryBean
For a singleton, this should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

FactoryBean
The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
