Prior to this commit, the `NettyHeadersAdapter` would directly delegate
the `add()` and `set()` calls to the adapted
`io.netty.handler.codec.http.HttpHeaders`. This implementation rejects
`null` values with exceptions.
This commit aligns the behavior here with other implementations, by not
rejecting null values but simply ignoring them.
Fixes gh-26274
HttpMessageWriter implementations now attach the request log prefix
as a hint to created data buffers when the logger associated with
the writer is at DEBUG level.
Closes gh-26230
This commit improves the Javadoc for the `ForwardedHeaderFilter`
(Servlet Filter) and `ForwardedHeaderTransformer` (reactive variant) so
as to mention security considerations linked to Forwarded HTTP headers.
Closes gh-26081
This commit adds support for sending Server-Sent Events in WebMvc.fn,
through the ServerResponse.sse method that takes a SseBuilder DSL.
It also includes reference documentation.
Closes gh-25920
This commit introduces the following changes:
- Converters/codecs are now used based on generic type info.
- On WebMvc and WebFlux, kotlinx.serialization is enabled along
to Jackson because it only serializes Kotlin @Serializable classes
which is not enough for error or actuator endpoints in Boot as
described on spring-projects/spring-boot#24238.
TODO: leverage Kotlin/kotlinx.serialization#1164 when fixed.
Closes gh-26147
This commit only writes the 'charset' parameter in the written headers
if it is non-default (not UTF-8), since RFC7578 states that the only
allowed parameter is 'boundary'.
Closes gh-25885
There are more locations which could benefit from not using a
toCharArray on a String, but rather use the charAt method from
the String itself. This to prevent an additional copy of the
char[] being created.
The migration from JUnit 4 assertions to AssertJ assertions resulted in
several unnecessary casts from int to long that actually cause
assertions to pass when they should otherwise fail.
This commit fixes all such bugs for the pattern `.isNotEqualTo((long)`.
Prior to this commit, references to `JsonGenerator` and
`ByteArrayBuilder` were not closed/released within codecs calls.
This prevents Jackson from reusing more efficiently shared memory
resources.
This commit properly closes/releases Jackson resources in Spring MVC,
Spring WebFlux and Spring Messaging codecs.
A benchmark on WebFlux codecs (in both single value/streaming mode)
shows significant throughput and allocation improvements for small
payloads.
Closes gh-25910
