This commit updates the content-type for form data to not include the
charset, unless it is different from the default charset.
Some servers don't handle charset parameter and the spec is unclear.

This commit ensures that, when creating a RestClient.Builder from a
RestTemplate, the UriBuilderFactory is only copied if it has been
changed from the default values.
Before this commit, the UriBuilderFactory was effectively alway copied,
resulting in not being able to use a baseUrl.
This commit also introduces a small memory optimization in
DefaultUriBuilderFactory, so that default environment variables are
created lazily.
Closes gh-32180
To improve consistency and avoid confusion regarding primitive types
and their wrapper types, this commit ensures that we always use class
literals for primitive types.
For example, instead of using the `Void.TYPE` constant, we now
consistently use `void.class`.
The behavior for the toString() implementation for annotations changed
in JDK 19, per my request to the JDK team (see link below).
Specifically, since JDK 19, the toString() implementation for annotation
proxies created by the JDK started using canonical names instead of
binary names for types.
See https://bugs.openjdk.org/browse/JDK-8281462
Prior to this commit, the `RestTemplate` observation instrumentation
would only record `RestClientException` and `IOException` as errors in
the observation. Other types of errors can be thrown by custom
components, such as `ResponseErrorHandler` and in this case they aren't
recorded with the observation.
Also, the current instrumentation does not create any observation scope
around the execution. While this would have a limited benefit as no
application code is executed there, developers could set up custom
components (such as, again, `ResponseErrorHandler`) that could use
contextual logging with trace ids.
This commit ensures that all `Throwable` are recorded as errors with the
observations and that an observation `Scope` is created around the
execution of the client exchange.
Fixes gh-32060
This commit makes sure that, when building a RestClient based on the
configuration of a RestTemplate, the request factory is unwrapped if it
is a InterceptingClientHttpRequestFactory.
Closes gh-32038
This commit ensures that setting the Content-Length through
setHeader("Content-Length", x") has the same effect as calling
setContentLength in the ShallowEtagHeaderFilter. It also filters out
Content-Type headers similarly to Content-Length.
Closes gh-32039
This change moves container element properties from ParameterErrors
to base class ParameterValidationResult, and makes that support
independent of whether violations are nested within a container
element bean or through constraints on container elements, e.g.
`List<@NotBlank String>`.
Closes gh-31887
This commit adds CORS support for Private Network Access
by adding an Access-Control-Allow-Private-Network response
header when the preflight request is sent with an
Access-Control-Request-Private-Network header and that
Private Network Access has been enabled in the CORS
configuration.
See https://developer.chrome.com/blog/private-network-access-preflight/
for more details.
Closes gh-28546
This commit updates the description of RequestHandledEvent to avoid
providing a misleading status as the absence of a failure logs OK which
can be inaccurate.
Closes gh-27595
Prior to this commit, the `ForwardedHeaderFilter` and the forwarded
header utils would throw `IllegalArgumentException` and
`IllegalStateException` when request headers are invalid and cannot be
parsed for Forwarded handling.
This commit aligns the behavior with the WebFlux counterpart by
rejecting such requests with HTTP 400 responses directly.
Fixes gh-31842
Prior to this commit, the `WebHttpHandlerBuilder` would only configure
a custom observation convention if there is a single convention in the
application context. It would other wise use the default.
This commit aligns with the previous Spring Boot behavior where multiple
conventions setups are rejected as invalid with
`NoUniqueBeanDefinitionException`.
Fixes gh-31864
DataBinder should skip any jakarta.validation.Validator yielding
to method validation when that is expected. This change improves
the check to skip by unwrapping the validator from in a
SmartValidator before checking if it is for bean validation.
Closes gh-31711
