Method Detail

all

public static RequestPredicate all()

Return a RequestPredicate that always matches.

Returns:

a predicate that always matches

method

public static RequestPredicate method(HttpMethod httpMethod)

Return a RequestPredicate that matches if the request's HTTP method is equal to the given method.

Parameters:

httpMethod - the HTTP method to match against

Returns:

a predicate that tests against the given HTTP method

methods

public static RequestPredicate methods(HttpMethod... httpMethods)

Return a RequestPredicate that matches if the request's HTTP method is equal to one the of the given methods.

Parameters:

httpMethods - the HTTP methods to match against

Returns:

a predicate that tests against the given HTTP methods

Since:

5.1

path

public static RequestPredicate path(String pattern)

Return a RequestPredicate that tests the request path against the given path pattern.

Parameters:

pattern - the pattern to match to

Returns:

a predicate that tests against the given path pattern

pathPredicates

public static Function<String,RequestPredicate> pathPredicates(PathPatternParser patternParser)

Return a function that creates new path-matching RequestPredicates from pattern Strings using the given PathPatternParser.

This method can be used to specify a non-default, customized PathPatternParser when resolving path patterns.

Parameters:

patternParser - the parser used to parse patterns given to the returned function

Returns:

a function that resolves a pattern String into a path-matching RequestPredicates instance

headers

public static RequestPredicate headers(Predicate<ServerRequest.Headers> headersPredicate)

Return a RequestPredicate that tests the request's headers against the given headers predicate.

Parameters:

headersPredicate - a predicate that tests against the request headers

Returns:

a predicate that tests against the given header predicate

contentType

public static RequestPredicate contentType(MediaType... mediaTypes)

Return a RequestPredicate that tests if the request's content type is included by any of the given media types.

Parameters:

mediaTypes - the media types to match the request's content type against

Returns:

a predicate that tests the request's content type against the given media types

accept

public static RequestPredicate accept(MediaType... mediaTypes)

Return a RequestPredicate that tests if the request's accept header is compatible with any of the given media types.

Parameters:

mediaTypes - the media types to match the request's accept header against

Returns:

a predicate that tests the request's accept header against the given media types

GET

public static RequestPredicate GET(String pattern)

Return a RequestPredicate that matches if request's HTTP method is GET and the given pattern matches against the request path.

Parameters:

pattern - the path pattern to match against

Returns:

a predicate that matches if the request method is GET and if the given pattern matches against the request path

HEAD

public static RequestPredicate HEAD(String pattern)

Return a RequestPredicate that matches if request's HTTP method is HEAD and the given pattern matches against the request path.

Parameters:

pattern - the path pattern to match against

Returns:

a predicate that matches if the request method is HEAD and if the given pattern matches against the request path

POST

public static RequestPredicate POST(String pattern)

Return a RequestPredicate that matches if request's HTTP method is POST and the given pattern matches against the request path.

Parameters:

pattern - the path pattern to match against

Returns:

a predicate that matches if the request method is POST and if the given pattern matches against the request path

PUT
