@Component @Order(value=-2147483648) public class ErrorPageFilter extends AbstractConfigurableEmbeddedServletContainer implements Filter, NonEmbeddedServletContainerFactory
AbstractConfigurableEmbeddedServletContainer
for non-embedded
applications (i.e. deployed WAR files). It registers error pages and handles
application errors by filtering requests and forwarding to the error pages instead of
letting the container handle them. Error pages are a feature of the servlet spec but
there is no Java API for registering them in the spec. This filter works around that by
accepting error page registrations from Spring Boot's
EmbeddedServletContainerCustomizer
(any beans of that type in the context will
be applied to this container).Modifier and Type | Field and Description |
