Class TimeoutCallableProcessingInterceptor

java.lang.Object

org.springframework.web.context.request.async.CallableProcessingInterceptorAdapter

org.springframework.web.context.request.async.TimeoutCallableProcessingInterceptor

All Implemented Interfaces:

CallableProcessingInterceptor

public class TimeoutCallableProcessingInterceptor
extends CallableProcessingInterceptorAdapter

Sends a 503 (SERVICE_UNAVAILABLE) in case of a timeout if the response is not already committed. Registered at the end, after all other interceptors and therefore invoked only if no other interceptor handles the timeout.

Note that according to RFC 2616, a 503 without a 'Retry-After' header is interpreted as a 500 error and the client should not retry. Applications can install their own interceptor to handle a timeout and add a 'Retry-After' header if necessary.

3.2
