This commit adds support for Model-related return values types such as
Map, Model, @ModelAttribute annotated, and non-simple types, which
helps to clarify the logic in ViewResolutionResultHandler.
In order to be more "reactive", changed StringDecoder's default from
merging all buffers in the stream to a single buffer into splitting the
buffers along newline (\r, \n) characters.
This commit introduces DataBuffer.indexOf(IntPredicate) and
lastIndexOf(IntPredicate), for finding the index of a byte in a
DataBuffer.
It also introduces DataBufferUtils.tokenize, which tokenizes a
DataBuffer into separate tokens, given a delimiter function.
While View and ViewResolver play the same role as in spring-webmvc they
are now abstracted behind the HandlerResultHandler abstraction so that
top-level contracts don't reference them and the DispatcherHandler is
also unaware of their existence.
Furthermore view resolution and response body handling which are now at
the same level of abstraction (each is a HandlerResultHandler) will
also share code for content negotiation, so it makes sense for them to
be side by side.
This commit moves the reactive.view package to reactive.result.view
with the View and ViewResolver contracts (previously in the top-level
reactive package) also moving there.
When a null is returned from an @ResponseBody method, rather than
returning Mono.empty() immediately, convert it to Mono.empty() and
apply the same processing.
Currently that doesn't make a practical difference but it's more
accurate to do it this way. Eventually it may mean the possibility
to turn empty values into something through an extension point
as we do with ResponseBodyAdvice in Spring MVC today.
Normally heartbeats keep connections from hanging. However in some
cases a connection may hang before a CONNECTED frame is received
and heartbeats are put in place. This commit adds a change to enforce
a 60 limit on receiving the CONNECTED frame.
