This commit refines WebMVC and WebFlux argument resolution in order to
convert properly Kotlin value class arguments by using the type of the
value instead of the type of the value class.
Closes gh-32353
This commit restores support for Kotlin extensions in
web handlers, and adds support for invoking reflectively
suspending extension functions, as well as the other
features supported as of Spring Framework 6.1 like
value classes and default value for parameters.
Closes gh-31876
This commit refines InvocableHandlerMethod (both Servlet and
Reactive variants) in order to support annotated property
accessors as they translate into regular Java methods, instead
of throwing a NullPointerException.
Closes gh-31856
This commit fixes a regression introduced by gh-21139
via the usage of Kotlin reflection to invoke HTTP
handler methods. It ensures that kotlin.Unit is treated
as void by returning null.
It also polishes CoroutinesUtils to have a consistent
handling compared to the regular case, and adds related
tests to prevent future regressions.
Closes gh-31648
This commit moves ServerWebExchange Kotlin extensions
where they belong: in the spring-web module with the
org.springframework.web.server package, like
ServerWebExchange itself.
The extensions in the wrong location are deprecated
and semi-automated migration to the new variants is
made possible via @Deprecated + ReplaceWith(...).
Some tests have been added as well.
Closes gh-31046
This commit updates WebMVC converters and WebFlux
encoders/decoders to support custom serializers
with Kotlin Serialization when specified via
a custom SerialFormat.
It also turns the serializers cache to a non-static
field in order to allow per converter/encoder/decoder
configuration.
Closes gh-30870
Now that HttpClientAdapter is deprecated and replaced by HttpExchangeAdapter
and ReactorHttpExchangeAdapter, our tests should use the new contracts.
See gh-30117
This commit adds support for Kotlin parameter default values
in handler methods. It allows to write:
@RequestParam value: String = "default"
as an alternative to:
@RequestParam(defaultValue = "default") value: String
Both Spring MVC and WebFlux are supported, including on
suspending functions.
Closes gh-21139
HttpServiceProxyFactoryExtensions.kt has been mistakenly created
in spring-webflux module instead of spring-web, breaking JPMS for
WebFlux users.
This commit moves this file and related tests to the spring-web
module.
Closes gh-30042
This commit refines ModelAttributeMethodProcessor Kotlin exception
handling in order to throw a proper MethodArgumentNotValidException
instead of a NullPointerException when Kotlin null-safety constraints
are not fulfilled, translating to an HTTP error with 400 status code
(Bad Request) instead of 500 (Internal Server Error).
Closes gh-23846
This commit introduces additional constructors in MockClientHttpRequest
and MockClientHttpResponse that were previously only present in the
internal "test fixtures" in spring-web.
This commit also aligns the mocks in spring-test with the test fixtures
in spring-web to simplify continued maintenance of the mocks and test
fixtures.
Closes gh-29670
This commit introduces support for CBOR and Protobuf using Kotlin
serialization. Support comes in the form of Encoder/Decoder as well
as HttpMessageConverters. Seperate abstract base classes supply support
for binary and string (de)serialization.
The exising JSON codecs and message converters have been migrated to
use the new base classes.
Closes gh-27628
After gh-29068, some Type instances can throw an
IllegalArgumentException. This commit catches them
properly to just return a null serializer in that
case.
Closes gh-29192
Remove support for open polymorphic serialization in
kotlinx.serialization web converters and codecs in order
to prevent serialization handling suitable for Jackson
or other general purpose Java JSON libraries.
This will probably need further refinements for collections
for example, and could ultimately be fixed when
kotlinx.serialization will provide a dedicated function to
evaluate upfront if a type can be serialized or not.
Closes gh-26298
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
