This commit turns TypeMismatchException thrown in
ModelAttributeMethodArgumentResolver#createAttribute into
proper ServerWebInputException in order get HTTP response
with 400 Bad Request status code instead of 500 Internal error.
Closes gh-31045
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
The method includes logic that is currently in
ViewResolutionResultHandler but fits well in BindingContext and also
includes the call to saveModel method from the InitBinderBindingContext
subclass, which was called too early until now from
RequestMappingHandlerAdapter before the model has been fully updated.
This mirrors a similar method in ModelFactory on the Spring MVC side
which also combines those two tasks.
Closes gh-30821
Now that HttpClientAdapter is deprecated and replaced by HttpExchangeAdapter
and ReactorHttpExchangeAdapter, our tests should use the new contracts.
See gh-30117
To handle method validation errors in ResponseEntityExceptionHandler,
MethodValidationException and associated types should not depend on
Bean Validation. To that effect:
1. MethodValidationResult and ParameterValidationResult no longer make
the underlying ConstraintViolation set available, and instead expose
only the adapted validation errors (MessageSourceResolvable, Errors),
analogous to what SpringValidatorAdapter does. And likewise
MethodValidationException no longer extends ConstraintViolationException.
2. MethodValidationPostProcessor has a new property
adaptConstraintViolations to decide whether to simply raise
ConstraintViolationException, or otherwise to adapt the ConstraintViolations
and raise MethodValidationException instead, with the former is the default
for compatibility.
3. As a result, the MethodValidator contract can now expose methods that
return MethodValidationResult, which provided more flexibility for handling,
and it allows MethodValidationAdapter to implement MethodValidator directly.
4. Update Javadoc in method validation classes to reflect this shift, and
use terminology consistent with Spring validation in classes without an
explicit dependency on Bean Validation.
