public interface EmbeddedServletContainerCustomizer

Strategy interface for customizing auto-configured embedded servlet containers. Any beans of this type will get a callback with the container factory before the container itself is started, so you can set the port, address, error pages etc.

Beware: calls to this interface are usually made from a EmbeddedServletContainerCustomizerBeanPostProcessor which is a BeanPostProcessor (so called very early in the ApplicationContext lifecycle). It might be safer to lookup dependencies lazily in the enclosing BeanFactory rather than injecting them with @Autowired.
