public class HttpRequestHandlingMessagingGateway extends HttpRequestHandlingEndpointSupport implements HttpRequestHandler
web.xml
where the servlet and bean both have the
same name. If the HttpRequestHandlingEndpointSupport.expectReply
property is set to true, a response can generated from a reply Message.
Otherwise, the gateway will play the role of a unidirectional Channel Adapter with a simple status-based response
(e.g. 200 OK).
The default supported request methods are GET and POST, but the list of values can be configured with the
RequestMapping.methods
property. The payload generated from a GET request (or HEAD or OPTIONS if supported) will
be a MultiValueMap
containing the parameter values. For a request containing a body (e.g. a POST), the type
of the payload is determined by the request payload type
.
If the HTTP request is a multipart and a "multipartResolver" bean has been defined in the context, then it will be
converted by the MultipartAwareFormHttpMessageConverter
as long as the default message converters have not
been overwritten (although providing a customized instance of the Multipart-aware converter is also an option).
By default a number of HttpMessageConverter
s are already configured. The list can be overridden by calling
the HttpRequestHandlingEndpointSupport.setMessageConverters(List)
method.
