This commit makes sure to initialize any HandlerMapping defined in the
context when searching for resource handlers. Previously, the detection
algorithm was looking up for `SimpleUrlHandlerMapping` while the
declared target type in WebMvcConfigurationSupport is HandlerMapping.
If the application uses lazy initialization, the lookup algorithm would
not force that bean to be initialized.

Prior to this commit, `ExchangeFilterFunction` could only get the
current observation from the reactor context. This is particularly
useful when such filters want to add KeyValues to the observation
context.
This commit makes this use case easier by adding the context of the
current observation as a request attribute. This also aligns the
behavior with other instrumentations.
Fixes gh-31609
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
Prior to this commit, the getResource() methods in PathResourceResolver
implementations allowed an exception thrown from Resource#getURL() to
propagate instead of logging a warning about the missing resource as
intended.
This commit modifies the getResource() methods in PathResourceResolver
implementations so that the log messages include the output of the
toString() implementations of the underlying resources instead of their
getURL() implementations, which may throw an exception.
Furthermore, logging the toString() output of resources aligns with the
existing output for "allowed locations" in the same log message.
Note that the toString() implementations could potentially also throw
exceptions, but that is considered less likely.

This commit surfaces the ETag generation feature for both
`ResourceHttpRequestHandler` and `ResourceWebHandler` on their
respective `ResourceHandlerRegistration` for easier configuration.

Use the helper to reduce logging when an @ExceptionHandler fails
to write to the response due to a network failure where the client
has gone away.
Closes gh-26181
This commit replaces uses of onErrorResume() with
- onErrorMap() in places where onErrorResume() is just used to map to a
different exception.
- onErrorComplete() where onErrorResume() just maps to Mono.empty().
- onErrorReturn() where onErrorResum() just maps to Mono.just().
Closes gh-31352
