构造器详细资料

• AntPathMatcher

  public AntPathMatcher()

  Create a new instance with the DEFAULT_PATH_SEPARATOR.

• AntPathMatcher

  public AntPathMatcher​(String pathSeparator)

  A convenient, alternative constructor to use with a custom path separator.

  参数:

  pathSeparator - the path separator to use, must not be null.

  从以下版本开始:

  4.1

方法详细资料

• setPathSeparator

  public void setPathSeparator​(String pathSeparator)

  Set the path separator to use for pattern parsing.

  Default is "/", as in Ant.

• setCaseSensitive

  public void setCaseSensitive​(boolean caseSensitive)

  Specify whether to perform pattern matching in a case-sensitive fashion.

  Default is true. Switch this to false for case-insensitive matching.

  从以下版本开始:

  4.2

• setTrimTokens

  public void setTrimTokens​(boolean trimTokens)

  Specify whether to trim tokenized paths and patterns.

  Default is false.

• setCachePatterns

  public void setCachePatterns​(boolean cachePatterns)

  Specify whether to cache parsed pattern metadata for patterns passed into this matcher's match(java.lang.String, java.lang.String) method. A value of true activates an unlimited pattern cache; a value of false turns the pattern cache off completely.

  Default is for the cache to be on, but with the variant to automatically turn it off when encountering too many patterns to cache at runtime (the threshold is 65536), assuming that arbitrary permutations of patterns are coming in, with little chance for encountering a recurring pattern.

  从以下版本开始:

  4.0.1

• isPattern

  public boolean isPattern​(String path)

  从接口复制的说明: PathMatcher
  Does the given path represent a pattern that can be matched by an implementation of this interface?

  If the return value is false, then the PathMatcher.match(java.lang.String, java.lang.String) method does not have to be used because direct equality comparisons on the static path Strings will lead to the same result.

  指定者:

  isPattern 在接口中 PathMatcher

  参数:

  path - the path String to check

  返回:

  true if the given path represents a pattern

• match

  public boolean match​(String pattern,
                       String path)

  从接口复制的说明: PathMatcher
  Match the given path against the given pattern, according to this PathMatcher's matching strategy.

  指定者:

  match 在接口中 PathMatcher

  参数:

  pattern - the pattern to match against

  path - the path String to test

  返回:

  true if the supplied path matched, false if it didn't

• matchStart

  public boolean matchStart​(String pattern,
                            String path)

  从接口复制的说明: PathMatcher
  Match the given path against the corresponding part of the given pattern, according to this PathMatcher's matching strategy.

  Determines whether the pattern at least matches as far as the given base path goes, assuming that a full path may then match as well.

  指定者:

  matchStart 在接口中 PathMatcher

  参数:

  pattern - the pattern to match against

  path - the path String to test

  返回:

  true if the supplied path matched, false if it didn't

• doMatch

  protected boolean doMatch​(String pattern,
                            String path,
                            boolean fullMatch,
                            Map<String,​String> uriTemplateVariables)

  Actually match the given path against the given pattern.

  参数:

  pattern - the pattern to match against

  path - the path String to test

  fullMatch - whether a full pattern match is required (else a pattern match as far as the given base path goes is sufficient)

  返回:

  true if the supplied path matched, false if it didn't

• tokenizePattern

  protected String[] tokenizePattern​(String pattern)

  Tokenize the given path pattern into parts, based on this matcher's settings.

  Performs caching based on setCachePatterns(boolean), delegating to tokenizePath(String) for the actual tokenization algorithm.

  参数:

  pattern - the pattern to tokenize

  返回:

  the tokenized pattern parts

• tokenizePath

  protected String[] tokenizePath​(String path)

  Tokenize the given path String into parts, based on this matcher's settings.

  参数:

  path - the path to tokenize

  返回:

  the tokenized path parts

• getStringMatcher

  protected AntPathMatcher.AntPathStringMatcher getStringMatcher​(String pattern)

  Build or retrieve an AntPathMatcher.AntPathStringMatcher for the given pattern.

  The default implementation checks this AntPathMatcher's internal cache (see setCachePatterns(boolean)), creating a new AntPathStringMatcher instance if no cached copy is found.

  When encountering too many patterns to cache at runtime (the threshold is 65536), it turns the default cache off, assuming that arbitrary permutations of patterns are coming in, with little chance for encountering a recurring pattern.

  This method may be overridden to implement a custom cache strategy.

  参数:

  pattern - the pattern to match against (never null)

  返回:

  a corresponding AntPathStringMatcher (never null)

  setCachePatterns(boolean)

• extractPathWithinPattern

  public String extractPathWithinPattern​(String pattern,
                                         String path)

  Given a pattern and a full path, determine the pattern-mapped part.

  For example:

  • '/docs/cvs/commit.html' and '/docs/cvs/commit.html -> ''
  • '/docs/*' and '/docs/cvs/commit -> 'cvs/commit'
  • '/docs/cvs/*.html' and '/docs/cvs/commit.html -> 'commit.html'
  • '/docs/**' and '/docs/cvs/commit -> 'cvs/commit'
  • '/docs/**\/*.html' and '/docs/cvs/commit.html -> 'cvs/commit.html'
  • '/*.html' and '/docs/cvs/commit.html -> 'docs/cvs/commit.html'
  • '*.html' and '/docs/cvs/commit.html -> '/docs/cvs/commit.html'
  • '*' and '/docs/cvs/commit.html -> '/docs/cvs/commit.html'

  Assumes that match(java.lang.String, java.lang.String) returns true for 'pattern' and 'path', but does not enforce this.

  指定者:

  extractPathWithinPattern 在接口中 PathMatcher

  参数:

  pattern - the path pattern

  path - the full path to introspect

  返回:

  the pattern-mapped part of the given path (never null)

• extractUriTemplateVariables

  public Map<String,​String> extractUriTemplateVariables​(String pattern,
                                                              String path)

  从接口复制的说明: PathMatcher
  Given a pattern and a full path, extract the URI template variables. URI template variables are expressed through curly brackets ('{' and '}').

  For example: For pattern "/hotels/{hotel}" and path "/hotels/1", this method will return a map containing "hotel"->"1".

  指定者:

  extractUriTemplateVariables 在接口中 PathMatcher

  参数:

  pattern - the path pattern, possibly containing URI templates

  path - the full path to extract template variables from

  返回:

  a map, containing variable names as keys; variables values as values

• combine

  public String combine​(String pattern1,
                        String pattern2)

  Combine two patterns into a new pattern.

  This implementation simply concatenates the two patterns, unless the first pattern contains a file extension match (e.g., *.html). In that case, the second pattern will be merged into the first. Otherwise, an IllegalArgumentException will be thrown.

  Examples

  Pattern 1	Pattern 2	Result
  null	null
  /hotels	null	/hotels
  null	/hotels	/hotels
  /hotels	/bookings	/hotels/bookings
  /hotels	bookings	/hotels/bookings
  /hotels/*	/bookings	/hotels/bookings
  /hotels/**	/bookings	/hotels/**/bookings
  /hotels	{hotel}	/hotels/{hotel}
  /hotels/*	{hotel}	/hotels/{hotel}
  /hotels/**	{hotel}	/hotels/**/{hotel}
  /*.html	/hotels.html	/hotels.html
  /*.html	/hotels	/hotels.html
  /*.html	/*.txt	IllegalArgumentException

  指定者:

  combine 在接口中 PathMatcher

  参数:

  pattern1 - the first pattern

  pattern2 - the second pattern

  返回:

  the combination of the two patterns

  抛出:

  IllegalArgumentException - if the two patterns cannot be combined

• getPatternComparator

  public Comparator<String> getPatternComparator​(String path)

  Given a full path, returns a Comparator suitable for sorting patterns in order of explicitness.

  ThisComparator will sort a list so that more specific patterns (without uri templates or wild cards) come before generic patterns. So given a list with the following patterns:

  1. /hotels/new
  2. /hotels/{hotel}
  3. /hotels/*

  the returned comparator will sort this list so that the order will be as indicated.

  The full path given as parameter is used to test for exact matches. So when the given path is /hotels/2, the pattern /hotels/2 will be sorted before /hotels/1.

  指定者:

  getPatternComparator 在接口中 PathMatcher

  参数:

  path - the full path to use for comparison

  返回:

  a comparator capable of sorting patterns in order of explicitness
