classes.
Deprecation Note:
In 5.2.4,useSuffixPatternMatch
and
useRegisteredSuffixPatternMatch
were deprecated in order to discourage use of path extensions for request
mapping and for content negotiation (with similar deprecations in
ContentNegotiationManagerFactoryBean
). For further context, please read issue
#24179.- Since:

setPatternParser
Description copied from class:AbstractHandlerMapping
Set thePathPatternParser
to parsepatterns
with for URL path matching. Parsed patterns provide a more modern and efficient alternative to String path matching viaAntPathMatcher
.Note: This property is mutually exclusive with the below properties, all of which are not necessary for parsed patterns and are ignored when a
PathPatternParser
is available:AbstractHandlerMapping.setAlwaysUseFullPath(boolean)
-- parsed patterns always use the full path and consider the servletPath only when a Servlet is mapped by path prefix.AbstractHandlerMapping.setRemoveSemicolonContent(boolean)
-- parsed patterns always ignore semicolon content for path matching purposes, but path parameters remain available for use in controllers via@MatrixVariable
.AbstractHandlerMapping.setUrlDecode(boolean)
-- parsed patterns match one decoded path segment at a time and therefore don't need to decode the full path.AbstractHandlerMapping.setUrlPathHelper(org.springframework.web.util.UrlPathHelper)
-- for parsed patterns, the request path is parsed once inDispatcherServlet
or inServletRequestPathFilter
usingServletRequestPathUtils
and cached in a request attribute.AbstractHandlerMapping.setPathMatcher(org.springframework.util.PathMatcher)
-- a parsed patterns encapsulates the logic for path matching and does need aPathMatcher
.
By default, as of 6.0, this is set to a
PathPatternParser
instance with default settings and therefore use of parsed patterns is enabled. Set this tonull
to switch to String path matching viaAntPathMatcher
instead.- Overrides:
setPatternParser
in classAbstractHandlerMethodMapping<RequestMappingInfo>
- Parameters:
patternParser
- the parser to use
-
setUseSuffixPatternMatch
Deprecated.as of 5.2.4. See class level note on the deprecation of path extension config options. As there is no replacement for this method, in 5.2.x it is necessary to set it tofalse
. In 5.3 the default changes tofalse
and use of this property becomes unnecessary.Whether to use suffix pattern match (".*") when matching patterns to requests. If enabled a method mapped to "/users" also matches to "/users.*".By default value this is set to
false
.Also see
setUseRegisteredSuffixPatternMatch(boolean)
for more fine-grained control over specific suffixes to allow.Note: This property is ignored when
setPatternParser(PathPatternParser)
is configured. -
setUseRegisteredSuffixPatternMatch
Deprecated.as of 5.2.4. See class level note on the deprecation of path extension config options.Whether suffix pattern matching should work only against path extensions explicitly registered with theContentNegotiationManager
. This is generally recommended to reduce ambiguity and to avoid issues such as when a "." appears in the path for other reasons.By default this is set to "false".
Note: This property is ignored when
setPatternParser(PathPatternParser)
is configured. -
setUseTrailingSlashMatch
Deprecated.as of 6.0, seePathPatternParser.setMatchOptionalTrailingSeparator(boolean)
Whether to match to URLs irrespective of the presence of a trailing slash. If enabled a method mapped to "/users" also matches to "/users/".The default was changed in 6.0 from
true
tofalse
in order to support the deprecation of the property. -
setPathPrefixes
Configure path prefixes to apply to controller methods.Prefixes are used to enrich the mappings of every
@RequestMapping
method whose controller type is matched by the correspondingPredicate
. The prefix for the first matching predicate is used.Consider using
HandlerTypePredicate
to group controllers.- Parameters:
prefixes
- a map with path prefixes as key- Since:
- 5.1
-
getPathPrefixes
The configured path prefixes as a read-only, possibly empty map.- Since:
- 5.1
-
setContentNegotiationManager
Set theContentNegotiationManager
to use to determine requested media types. If not set, the default constructor is used. -
getContentNegotiationManager
Return the configuredContentNegotiationManager
. -
setEmbeddedValueResolver
Description copied from interface:EmbeddedValueResolverAware
Set the StringValueResolver to use for resolving embedded definition values.- Specified by:
setEmbeddedValueResolver
in interfaceEmbeddedValueResolverAware
-
afterPropertiesSet
public void afterPropertiesSet()Description copied from class:AbstractHandlerMethodMapping
Detects handler methods at initialization.- Specified by:
afterPropertiesSet
in interfaceInitializingBean
- Overrides:
afterPropertiesSet
in classAbstractHandlerMethodMapping<RequestMappingInfo>
- See Also:
-
useSuffixPatternMatch
Deprecated.as of 5.2.4. See deprecation notice onsetUseSuffixPatternMatch(boolean)
.Whether to use registered suffixes for pattern matching. -
useRegisteredSuffixPatternMatch
Deprecated.as of 5.2.4. See deprecation notice onsetUseRegisteredSuffixPatternMatch(boolean)
.Whether to use registered suffixes for pattern matching. -
useTrailingSlashMatch
public boolean useTrailingSlashMatch()Whether to match to URLs irrespective of the presence of a trailing slash. -
getFileExtensions
Deprecated.as of 5.2.4. See class-level note on the deprecation of path extension config options.Return the file extensions to use for suffix pattern matching. -
getBuilderConfiguration
Obtain aRequestMappingInfo.BuilderConfiguration
that can reflects the internal configuration of thisHandlerMapping
and can be used to setRequestMappingInfo.Builder.options(RequestMappingInfo.BuilderConfiguration)
.This is useful for programmatic registration of request mappings via
registerHandlerMethod(Object, Method, RequestMappingInfo)
.- Returns:
- the builder configuration that reflects the internal state
- Since:
- 5.3.14
-
isHandler
Whether the given type is a handler with handler methods.Expects a handler to have a type-level @
Controller
annotation.- Specified by:
isHandler
in classAbstractHandlerMethodMapping<RequestMappingInfo>
- Parameters:
beanType
- the type of the bean being checked- Returns:
- "true" if this a handler type, "false" otherwise.
-
getMappingForMethod
Uses method and type-level @RequestMapping
annotations to create the RequestMappingInfo.- Specified by:
getMappingForMethod
in classAbstractHandlerMethodMapping<RequestMappingInfo>
- Parameters:
method
- the method to provide a mapping forhandlerType
- the handler type, possibly a subtype of the method's declaring class- Returns:
- the created RequestMappingInfo, or
null
if the method does not have a@RequestMapping
annotation. - See Also:
-
getCustomTypeCondition
Provide a custom type-level request condition. The customRequestCondition
can be of any type so long as the same condition type is returned from all calls to this method in order to ensure custom request conditions can be combined and compared.Consider extending
AbstractRequestCondition
for custom condition types and usingCompositeRequestCondition
to provide multiple custom conditions.- Parameters:
handlerType
- the handler type for which to create the condition- Returns:
- the condition, or
null
-
getCustomMethodCondition
Provide a custom method-level request condition. The customRequestCondition
can be of any type so long as the same condition type is returned from all calls to this method in order to ensure custom request conditions can be combined and compared.Consider extending
AbstractRequestCondition
for custom condition types and usingCompositeRequestCondition
to provide multiple custom conditions.- Parameters:
method
- the handler method for which to create the condition- Returns:
- the condition, or
null
-
createRequestMappingInfo
protected RequestMappingInfo createRequestMappingInfo(RequestMapping requestMapping, @Nullable RequestCondition<?> customCondition) Create aRequestMappingInfo
from the supplied@RequestMapping
annotation, which is either a directly declared annotation, a meta-annotation, or the synthesized result of merging annotation attributes within an annotation hierarchy. -
resolveEmbeddedValuesInPatterns

- Parameters:
mapping
- the mapping for the handler methodhandler
- the handlermethod
- the method
-
registerHandlerMethod
Register a handler method and its unique mapping. Invoked at startup for each detected handler method.Note: To create the
RequestMappingInfo
, please usegetBuilderConfiguration()
and set the options onRequestMappingInfo.Builder.options(RequestMappingInfo.BuilderConfiguration)
to match how thisHandlerMapping
is configured. This is important for example to ensure use ofPathPattern
orPathMatcher
based matching.- Overrides:
registerHandlerMethod
