方法详细资料

isPattern

boolean isPattern(java.lang.String path)

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 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.

参数:

path - the path String to check

返回:

true if the given path represents a pattern

match

boolean match(java.lang.String pattern,
              java.lang.String path)

Match the given path against the given pattern, according to this PathMatcher's matching strategy.

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

boolean matchStart(java.lang.String pattern,
                   java.lang.String path)

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.

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

extractPathWithinPattern

java.lang.String extractPathWithinPattern(java.lang.String pattern,
                                          java.lang.String path)

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

This method is supposed to find out which part of the path is matched dynamically through an actual pattern, that is, it strips off a statically defined leading path from the given full path, returning only the actually pattern-matched part of the path.

For example: For "myroot/*.html" as pattern and "myroot/myfile.html" as full path, this method should return "myfile.html". The detailed determination rules are specified to this PathMatcher's matching strategy.

A simple implementation may return the given full path as-is in case of an actual pattern, and the empty String in case of the pattern not containing any dynamic parts (i.e. the pattern parameter being a static path that wouldn't qualify as an actual pattern). A sophisticated implementation will differentiate between the static parts and the dynamic parts of the given path pattern.

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

java.util.Map<java.lang.String,java.lang.String> extractUriTemplateVariables(java.lang.String pattern,
                                                                             java.lang.String path)

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".

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

getPatternComparator

java.util.Comparator<java.lang.String> getPatternComparator(java.lang.String path)

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

The full algorithm used depends on the underlying implementation, but generally, the returned Comparator will sort a list so that more specific patterns come before generic patterns.

参数:

path - the full path to use for comparison

返回:

a comparator capable of sorting patterns in order of explicitness

combine

java.lang.String combine(java.lang.String pattern1,
                         java.lang.String pattern2)

Combines two patterns into a new pattern that is returned.

The full algorithm used for combining the two pattern depends on the underlying implementation.

参数:

pattern1 - the first pattern

pattern2 - the second pattern

返回:

the combination of the two patterns

抛出:

java.lang.IllegalArgumentException - when the two patterns cannot be combined

urlContain

boolean urlContain(java.lang.String pattern,
                   java.lang.String url)

简单的地址模式包含: pattern *.aa.bb.cn url http://test.aa.bb.cn/c

参数:

pattern -

url -

返回:

urlMatch

boolean urlMatch(java.lang.String pattern,
                 java.lang.String url)

简单的地址模式匹配: pattern *.aa.bb.cn url http://test.aa.bb.cn

参数:

pattern -

url -

返回:
