类 PatternsRequestCondition

构造器详细资料

• PatternsRequestCondition

  public PatternsRequestCondition​(String... patterns)

  Creates a new instance with the given URL patterns. Each pattern that is not empty and does not start with "/" is prepended with "/".

  参数:

  patterns - 0 or more URL patterns; if 0 the condition will match to every request.

• PatternsRequestCondition

  public PatternsRequestCondition​(String[] patterns,
                                  UrlPathHelper urlPathHelper,
                                  PathMatcher pathMatcher,
                                  boolean useSuffixPatternMatch,
                                  boolean useTrailingSlashMatch)

  Additional constructor with flags for using suffix pattern (.*) and trailing slash matches.

  参数:

  patterns - the URL patterns to use; if 0, the condition will match to every request.

  urlPathHelper - for determining the lookup path of a request

  pathMatcher - for path matching with patterns

  useSuffixPatternMatch - whether to enable matching by suffix (".*")

  useTrailingSlashMatch - whether to match irrespective of a trailing slash

  Creates a new instance with the given URL patterns. Each pattern that is not empty and does not start with "/" is pre-pended with "/".

  参数:

  patterns - the URL patterns to use; if 0, the condition will match to every request.

  urlPathHelper - a UrlPathHelper for determining the lookup path for a request

  pathMatcher - a PathMatcher for pattern path matching

  useSuffixPatternMatch - whether to enable matching by suffix (".*")

  useTrailingSlashMatch - whether to match irrespective of a trailing slash

  fileExtensions - a list of file extensions to consider for path matching

方法详细资料

• getPatterns

  public Set<String> getPatterns()

• getContent

  protected Collection<String> getContent()

  从类复制的说明: AbstractRequestCondition
  Return the discrete items a request condition is composed of.

  For example URL patterns, HTTP request methods, param expressions, etc.

  指定者:

  getContent 在类中 AbstractRequestCondition<PatternsRequestCondition>

  返回:

  a collection of objects (never null)

• getToStringInfix

  protected String getToStringInfix()

  从类复制的说明: AbstractRequestCondition
  The notation to use when printing discrete items of content.

  For example " || " for URL patterns or " && " for param expressions.

  指定者:

  getToStringInfix 在类中 AbstractRequestCondition<PatternsRequestCondition>

• combine

  public PatternsRequestCondition combine​(PatternsRequestCondition other)

  Returns a new instance with URL patterns from the current instance ("this") and the "other" instance as follows:

  • If there are patterns in both instances, combine the patterns in "this" with the patterns in "other" using PathMatcher.combine(String, String).
  • If only one instance has patterns, use them.
  • If neither instance has patterns, use an empty String (i.e. "").

  参数:

  other - the condition to combine with.

  返回:

  a request condition instance that is the result of combining the two condition instances.

• getMatchingCondition

  public PatternsRequestCondition getMatchingCondition​(HttpServletRequest request)

  Checks if any of the patterns match the given request and returns an instance that is guaranteed to contain matching patterns, sorted via PathMatcher.getPatternComparator(String).

  A matching pattern is obtained by making checks in the following order:

  • Direct match
  • Pattern match with ".*" appended if the pattern doesn't already contain a "."
  • Pattern match
  • Pattern match with "/" appended if the pattern doesn't already end in "/"

  参数:

  request - the current request

  返回:

  the same instance if the condition contains no patterns; or a new condition with sorted matching patterns; or null if no patterns match.

• getMatchingPatterns

  public List<String> getMatchingPatterns​(String lookupPath)

  Find the patterns matching the given lookup path. Invoking this method should yield results equivalent to those of calling getMatchingCondition(javax.servlet.http.HttpServletRequest). This method is provided as an alternative to be used if no request is available (e.g. introspection, tooling, etc).

  参数:

  lookupPath - the lookup path to match to existing patterns

  返回:

  a collection of matching patterns sorted with the closest match at the top

• compareTo

  public int compareTo​(PatternsRequestCondition other,
                       HttpServletRequest request)

  Compare the two conditions based on the URL patterns they contain. Patterns are compared one at a time, from top to bottom via PathMatcher.getPatternComparator(String). If all compared patterns match equally, but one instance has more patterns, it is considered a closer match.

  It is assumed that both instances have been obtained via getMatchingCondition(HttpServletRequest) to ensure they contain only patterns that match the request and are sorted with the best matches on top.
