public Class PathPatternParser

extends Object
Class Inheritance
Imports
org.springframework.http.server.PathContainer, org.springframework.util.StringUtils
Parser for URI path patterns producing PathPattern instances that can then be matched to requests.

The PathPatternParser and PathPattern are specifically designed for use with HTTP URL paths in web applications where a large number of URI path patterns, continuously matched against incoming requests, motivates the need for efficient matching.

For details of the path pattern syntax see PathPattern.

Method Summary

Modifier and TypeMethod and Description
public PathContainer.Options
getPathOptions()

Get the configured pattern parsing options.

public String

Returns:

the updated pattern
initFullPathPattern(String
the pattern to initialize
pattern)

Prepare the given pattern for use in matching to full URL paths.

public boolean
isCaseSensitive()

Whether case-sensitive pattern matching is enabled.

public boolean
isMatchOptionalTrailingSeparator()

Deprecated since 6.0. as of 6.0 together with setMatchOptionalTrailingSeparator(boolean).
Whether optional trailing slashing match is enabled.
public PathPattern

Returns:

a PathPattern for quickly matching paths against request paths
parse(String
the input path pattern, e.g. /project/{name}
pathPattern)

Process the path pattern content, a character at a time, breaking it into path elements around separator boundaries and verifying the structure at each stage.

public void
setCaseSensitive(boolean caseSensitive)

Configure whether path pattern matching should be case-sensitive.

public void
setMatchOptionalTrailingSeparator(boolean matchOptionalTrailingSeparator)

Deprecated since 6.0. transparent support for trailing slashes is deprecated as of 6.0 in favor of configuring explicit redirects through a proxy, Servlet/web filter, or a controller.
Configure whether a PathPattern produced by this parser should automatically match request paths with a trailing slash.
public void
setPathOptions(PathContainer.Options pathOptions)

Set options for parsing patterns.

public PathPattern parse(String pathPattern) throws PatternParseException

Process the path pattern content, a character at a time, breaking it into path elements around separator boundaries and verifying the structure at each stage. Produces a PathPattern object that can be used for fast matching against paths. Each invocation of this method delegates to a new instance of the InternalPathPatternParser because that class is not thread-safe.

Parameters
pathPattern:String

the input path pattern, e.g. /project/{name}

Returns:PathPattern

a PathPattern for quickly matching paths against request paths

Exceptions
PatternParseException:
in case of parse errors
setCaseSensitiveback to summary
public void setCaseSensitive(boolean caseSensitive)

Configure whether path pattern matching should be case-sensitive.

The default is true.

setMatchOptionalTrailingSeparatorback to summary
public void setMatchOptionalTrailingSeparator(boolean matchOptionalTrailingSeparator)

Deprecated

since 6.0.

transparent support for trailing slashes is deprecated as of 6.0 in favor of configuring explicit redirects through a proxy, Servlet/web filter, or a controller.

Configure whether a PathPattern produced by this parser should automatically match request paths with a trailing slash.

If set to true a PathPattern without a trailing slash will also match request paths with a trailing slash. If set to false a PathPattern will only match request paths with a trailing slash.

The default was changed in 6.0 from true to false in order to support the deprecation of the property.

setPathOptionsback to summary
public void setPathOptions(PathContainer.Options pathOptions)

Set options for parsing patterns. These should be the same as the options used to parse input paths.

org.springframework.http.server.PathContainer.Options#HTTP_PATH is used by default.
