Prior to this commit, the `HttpMessageConverters` auto-configuration
would pick up `HttpMessageConverter<?>` beans from the context and
broadly apply them to both server and client converters setup.
This can cause several types of problems.
First, specific configurations only meant for server setup will also be
applied to the client side. For example, the Actuator JSOn configuration
is only meant to be applied to the server infrastructure.
Also, picking up converters from the context does not convey whether
such converters are meant to override the default ones or should be
configured as custom, in addition to the defaults.
For example, a bean extending `JacksonJsonHttpMessageConverter` can be
both meant to override the default with `builder.withJsonConverter` or
meant as an additional converter with `builder.addCustomConverter`.
This commit ensures that the auto-configurations contribute
`ClientHttpMessageConvertersCustomizer` and
`ServerHttpMessageConvertersCustomizer` beans instead of converter beans
directly. Applications can still contribute such beans and those will be
used.
Fixes gh-48310
This commit ensures that XML and JSON converters on both client and
server are configured using the dedicated methods on
`HttpMessageConverters`, instead of pushing them ahead of default
converters.
Closes gh-47917
Fixes gh-48096
Previously, Kotlin Serialization would be used too aggressively then
an alternative JSON converter was available. This could lead to
unwanted results when a response should have been serialized using
Jackson, for example, rather than Kotlin Serialization.
This commit addresses this by only allowing Kotlin Serialization to
serialize types that are not annotated with @Serializable when no
alternative JSON converter is available.
Fixes gh-48070
As of As of spring-projects/spring-framework#35733, Spring Framework has
a dedicated method for configuring a Kotlin Serialization converter
specifically.
This commit uses this method instead of configuring the Kotlin
Serialization JSON support as a custom converter. This also removes the
`@Order` on the Kotlin converter bean itself, as there is no need to
order it in the list of custom converters anymore.
Closes gh-47917
Previously, the default client and server HTTP message converter
customizers were ordered with lowest precedence. This made it
impossible to guarantee that another customizer would be able to go
after the default customizers, preventing their customizations from
being reliably overridden.
This commit updates the definitions of the default customizers to
order them at 0. This allows additional customizers to be ordered
either before or after them. Usage of the customizers is now always
ordered (previously Spring MVC's was not).

Create `spring-boot-resttestclient` and `spring-boot-webtestclient`
modules to hold test client auto-configuration and `TestRestTemplate`
code.
Previous these classes were contained in `spring-boot-resetclient-test`
and `spring-boot-webclient-test` which was incorrect since the `-test`
modules should hold code need to test the given modules, not supporting
test classes.

Prior to this commit, Spring Boot had an `HttpMessageConverters` class
that allowed, to configure message converter instances for MVC server
applications and traditional Spring HTTP clients.
As of Spring Framework 7.0, Framework ships its own
`HttpMessageConverters` class, aligning with the existing codecs
configuration on the WebFlux side. As a result, a few methods taking
`List<HttpMessageConverter>` as arguments were deprecated in favor of
the new arrangement.
This commit adapts to the Framework changes by deprecating Boot's
`HttpMessageConverters` in favor of Framework's. This splits the client
and server configuration as they are meant to be managed separately.
Applications can still contribute `HttpMessageConverters` (Boot's
variant) beans but the type itself is now deprecated.
Instead, applications should now contribute
`ClientHttpMessageConvertersCustomizer` and
`ServerHttpMessageConvertersCustomizer` beans to customize message
converters.
Closes gh-46411
This commit removes the "kotlin-serialization" option from the
`spring.http.converters.preferred-json-mapper` and configures the kotlin
serialization http message converter ahead of the preferred JSON
converter.
This effectively makes Kotlin Serialization a converter that is
considered first for JSON support, and then Jackson/Jsonb/Gson is
considered as fallback.
