类 TimeoutDeferredResultProcessingInterceptor
- java.lang.Object
- org.springframework.web.context.request.async.DeferredResultProcessingInterceptorAdapter
- org.springframework.web.context.request.async.TimeoutDeferredResultProcessingInterceptor
- 所有已实现的接口:
DeferredResultProcessingInterceptor
public class TimeoutDeferredResultProcessingInterceptor extends DeferredResultProcessingInterceptorAdapter
Sends a 503 (SERVICE_UNAVAILABLE) in case of a timeout if the response is not already committed. As of 4.2.8 this is done indirectly by returningAsyncRequestTimeoutException
as the result of processing which is then handled by Spring MVC's default exception handling as a 503 error.Registered at the end, after all other interceptors and therefore invoked only if no other interceptor handles the timeout.
Note that according to RFC 7231, 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.

在接口中DeferredResultProcessingInterceptor
- 覆盖:
handleTimeout
在类中DeferredResultProcessingInterceptorAdapter
- 参数:
request
- the current requestresult
- the DeferredResult for the current request; if theDeferredResult
is set, then concurrent processing is resumed and subsequent interceptors are not invoked- 返回:
true
if processing should continue, orfalse
if other interceptors should not be invoked- 抛出:
Exception
- in case of errors
