Prior to this commit, the `header(String, String)` method in the
ServerHttpRequest.Builder API actually added a header value instead of
setting or overriding a header value. Since this conflicted with the
stated behavior in the Javadoc as well as the original intention of the
method, we have decided to introduce an overloaded variant
`header(String, String...)` which accepts a var-args list of header
values to set or override.
In addition, this commit deprecates the existing `header(String, String)`
method for removal in Spring Framework 5.2.
In order not to be a breaking change for custom implementations of the
builder API, this commit implements the new `header(String, String...)`
method as an interface `default` method, with the intent to remove the
default implementation in Spring Framework 5.2

To make the switching of separators complete, it is also important to
know whether the decoding of path segment values and the parsing of
path param should be done as those are applied transparently.
This commit replaces the recently added separator argument to
PathContainer.parsePath with an Options type with two predefined
constants. One for HTTP URLs with automatic decoding and parsing of
path params, and another for "." separated message routes without
decoding except for encoded sequences of the separator itself.

OncePerRequestFilter now has a doFilter method that allows separate
processing of nested ERROR dispatches. This is useful for filters
that wrap the request and response.
Closes gh-23196
The DefaultMultipartMessageReader has been removed for 5.2 and will be
part of a future release. This commit switches back to the
SynchronossPartHttpMessageReader.

Prior to Spring Framework 5.1.3, MimeTypeUtils.parseMimeTypes() and
MediaType.parseMediaTypes() ignored empty entries, but 5.1.3 introduced
a regression in that an empty entry -- for example, due to a trailing
comma in the list of media types in an HTTP Accept header -- would result
in a "406 Not Acceptable" response status.
This commit fixes this by filtering out empty entries before parsing
them into MimeType and MediaType instances. Empty entries are therefore
effectively ignored.
Fixes gh-23241
Commit 5008423408 added support for
multipart/* media types in FormHttpMessageConverter, but users still had
to manually register multipart/mixed as a supported media type in order
to POST multipart data with that content type.
This commit removes the need to manually register multipart/mixed as a
supported media type by registering it automatically in
FormHttpMessageConverter. In addition, this commit introduces
MULTIPART_MIXED and MULTIPART_MIXED_VALUE constants in MediaType.
Closes gh-23209
Prior to this commit, RestTemplate posted multipart with Content-Type
"multipart/form-data" even if the FormHttpMessageConverter configured
in the RestTemplate had been configured to support additional multipart
subtypes. This made it impossible to POST form data using a content
type such as "multipart/mixed" or "multipart/related".
This commit addresses this issue by updating FormHttpMessageConverter
to support custom multipart subtypes for writing form data.
For example, the following use case is now supported.
MediaType multipartMixed = new MediaType("multipart", "mixed");
restTemplate.getMessageConverters().stream()
.filter(FormHttpMessageConverter.class::isInstance)
.map(FormHttpMessageConverter.class::cast)
.findFirst()
.orElseThrow(() ->
new IllegalStateException("Failed to find FormHttpMessageConverter"))
.addSupportedMediaTypes(multipartMixed);
MultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
parts.add("field 1", "value 1");
parts.add("file", new ClassPathResource("myFile.jpg"));
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(multipartMixed);
HttpEntity<MultiValueMap<String, Object>> requestEntity =
new HttpEntity<>(parts, requestHeaders);
restTemplate.postForLocation("https://example.com/myFileUpload", requestEntity);
Closes gh-23159
This commit changes the new addSupportedMediaType(MediaType) method
to addSupportedMediaTypes(MediaType...), in order to allow registration
of multiple supported media types simultaneously.

Prior to this commit, all clients of
ControllerAdviceBean.findAnnotatedBeans() sorted the returned list
manually. In addition, clients within the core Spring Framework
unnecessarily used AnnotationAwareOrderComparator instead of
OrderComparator to sort the list.
This commit presorts the ControllerAdviceBean list using OrderComparator
directly within ControllerAdviceBean.findAnnotatedBeans().
Closes gh-23188
This commit introduces unit tests for the status quo in
ControllerAdviceBeanTests to serve as regression tests for future
changes to ControllerAdviceBean.
Prior to this commit, `PathPattern::extractPathWithinMapping`
would always use the default path pattern separator `/` when extracting
the path within the pattern of a matched route.
This commit ensures that `PathPattern` uses the configured separator
when extracting the path within the matched mapping.
Fixes gh-23168
Prior to this commit, the `PathPatternRouteMatcher` would always use the
default path pattern separator when parsing incoming route strings to
`RouteMatcher.Route` instances.
When the `PathPatternRouteMatcher` is configured with a
`PathPatternParser` that has a custom separator (e.g., `.`), then the
matching algorithm can't match routes against parsed patterns.
This commit ensures that the route matcher uses the configured separator
at all times.
Fixes gh-23167
Prior to this commit, RestTemplate and HttpMessageConverterExtractor did
not validate that the supplied HttpMessageConverter list contained no
null elements, which can lead to a NullPointerException when the
converters are accessed.
This commit improves the user experience by failing immediately if the
supplied HttpMessageConverter list contains a null element. This applies
to constructors for RestTemplate and HttpMessageConverterExtractor as
well as to RestTemplate#setMessageConverters().
Note, however, that RestTemplate#getMessageConverters() returns a mutable
list. Thus, if a user modifies that list so that it contains null values,
that will still lead to a NullPointerException when the converters are
accessed.
This commit also introduces noNullElements() variants for collections in
org.springframework.util.Assert.
Closes gh-23151
Prior to this commit, MockHttpServletRequest.setCookies() produced one
Cookie header per supplied cookie, resulting in multiple Cookie headers
which violates the specification.
This commit fixes this by ensuring that all cookie name-value pairs are
stored under a single Cookie header, separated by a semicolon.
Closes gh-23074
This commit allows to configure a custom path separator when parsing and
matching path patterns with `PathPatternParser`, but also when parsing
incoming paths as `PathContainer` instances.
Closes gh-23092
1. Add contentType and filename options to PartBuilder.
2. Revert recently committed #44659f since asyncPart can't properly
support Publisher of Part (only Mono, can't support filename), and
replace that with support for Part in the regular part method.
Closes gh-23083
