Prior to this commit, different resource resolvers would resolve
accepted codings from the HTTP request sent by the client. This would be
done with different implementations, which could lead to resolution
errors and desynchronizations.
This commit now introduced a new shared method in
`EncodedResourceResolver` (Servlet and Reactive) to perform a consisten
resolution.
Fixes gh-36507
Although this commit also changes the visibility of some test methods
to package-private, the remainder of that task will be addressed in
conjunction with gh-36496.
Closes gh-36495
Since the Spring Framework uses American English spelling, this commit
updates Javadoc and the reference manual to ensure consistency in that
regard. However, there are two exceptions to this rule that arise due
to their use within a technical context.
- We use "cancelled/cancelling" instead of "canceled/canceling" in
numerous places (including error messages).
- We use "implementor" instead of "implementer".
Closes gh-36470
This commit apply extra checks to ScriptTemplateView resource handling
with ResourceHandlerUtils, consistently with what is done with static
resource handling.
Closes gh-36458
Restore both WebMVC and WebFlux variants that were deleted
by mistake in commit 4db2f8ea1b.
This commit also removes the empty resource loader path, as it is not
needed for the main WEB-INF/ use case that is typically configured
explicitly by the user, and not needed to pass the restored tests.
Closes gh-36456
Prior to this commit, our implementation of Server Sent Events (SSE),
`SseEmitter` (MVC) and `ServerSentEvent` (WebFlux), would not guard
against invalid characters if the application mistakenly inserts such
characters in the `id` or `event` types.
Both implementations would also behave differently when it comes
to escaping comment multi-line events.
This commit ensures that both implementations handle multi-line comment
events and reject invalid characters in id/event types.
This commit also optimizes `String` concatenation and memory usage
when writing data.
Fixes gh-36440

1. Mathematical Distribution (Collision Reduction)
2. Pipelining and CPU Caching
3. Avoiding "Method Heavy" Expressions

Prior to this commit, flush calls on the output stream returned by
`ServletServerHttpResponse#getBody` would be delegated to the Servlet
response output stream.
This can cause performance issues when `HttpMessageConverter` and other
web components write and flush multiple times to the response body.
Here, the Servlet container is in a better position to flush to the
network at the optimal time and buffer the response body until then.
This is particularly true for `HttpMessageConverters` when they flush
many times the output stream, sometimes due to the underlying codec
library. Instead of revisiting the entire message converter contract, we
are here ignoring flush calls to that output stream.
This change does not affect the client side, nor the
`ServletServerHttpResponse#flush` calls.
This commit also introduces a new Spring property
`"spring.http.response.flush.enabled"` that reverts this behavior change
if necessary.
Closes gh-36385
The `AbstractMessageConverterMethodProcessor` is in charge of handling
controller method return values and to write those as HTTP response
messages. The content negotiation process is an important part.
The `MimeTypeUtils#sortBySpecificity` is in charge of sorting inbound
"Accept" media types by their specificity and reject them if the list
is too large, in order to protect the application from ddos attacks.
Prior to this commit, the content negotiation process would first get
the sorted "Accept" media types, the producible media types as
advertized by message converters - and collect the intersection of both
in a new list (also sorted by specificity). If the "Accept" list is
large enough (but under the limit), the list of compatible media types
could exceed that limit because duplicates could be introduced in that
list: several converters can produce the same content type.
This commit ensures that compatible media types are collected in a set
to avoid duplicates. Without that, exceeding the limit at this point
will throw an `InvalidMimeTypeException` that's not handled by the
processor and result in a server error.
Fixes gh-36300
Prior to this commit, the `HttpEntityMethodProcessor` would create a new
`ServletServerHttpRequest` input message to parse the native Servlet
request, but would not reuse it for reading the request body using the
message converters.
In gh-32471, we applied a change that updates HTTP headers accordingly
when request parameters are read. But not reusing the input message
means that we are losing this update when instantiating the resulting
`HttpEntity`.
This commit ensures that `HttpEntityMethodProcessor` uses the input
message it just created when decoding the request body.
Fixes gh-36298
This commit introduces ContextClassRequestBodyAdvice which adds a
"contextClass" hint allowing to resolve generics for Optional,
HttpEntity or ServerSentEvent container types.
Closes gh-36111
While an API version may be important for mapping in an ERROR dispatch,
it is more important to allow the original exception to be handled.
Closes gh-36058
Among HandlerMapping's some may not expect an API version. This is why
those that do must be careful not to raise API validation errors if
they don't match the request.
Closes gh-36059
This includes MethodParameter resolving getParameterName() by default now.
initParameterNameDiscovery(null) can be used to suppress such resolution.
Closes gh-36024
Return the requested resource as ErrorResponse.getDetailMessageArguments,
making it usable with message customization and i18n.
