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
Improve the performance of `FormContentFilter` by checking directly if
`contentType` is empty. This saves the need for an exception to thrown
then immediately caught.
Closes gh-23216
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, the Basic Authentication credentials were encoded
for each request.
This commit addresses this minor performance issue by caching the
encoded credentials in BasicAuthenticationInterceptor.
In addition, this commit introduces new encodeBasicAuth() and
setBasicAuth(String encodedCredentials) methods in HttpHeaders to
support this feature.
Closes gh-23204
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.
See gh-23203
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
Prior to this commit, the resolveBean() method in ControllerAdviceBean
looked up the @ControllerAdvice bean instance in the ApplicationContext
by name for every web request that involved lookups for global methods
annotated with @ExceptionHandler, @InitBinder, and @ModelAttribute.
This commit avoids the need for such repeated lookups in the
ApplicationContext by caching the resolved @ControllerAdvice bean
instance within ControllerAdviceBean once it has been resolved.
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
This commit makes sure that in DefaultMultipartMessageReader's
DefaultFilePart, the file is not closed before all bytes are written,
by using DataBufferUtils.write (see c1b6885191d6a50347aeaa14da994f0db88f26fe).
The commit also improves on the logging of the
DefaultMultipartMessageReader.
