Interface PathMatcher

All Known Implementing Classes:

AntPathMatcher

public interface PathMatcher

Strategy interface for String-based path matching.

Used by PathMatchingResourcePatternResolver, AbstractUrlHandlerMapping, PropertiesMethodNameResolver, and WebContentInterceptor.

The default implementation is AntPathMatcher, supporting the Ant-style pattern syntax.

Since:

1.2

Method Summary

String	extractPathWithinPattern(String pattern, String path) Given a pattern and a full path, determine the pattern-mapped part.
boolean	isPattern(String path) Does the given path represent a pattern that can be matched by an implementation of this interface?
boolean	match(String pattern, String path) Match the given path against the given pattern, according to this PathMatcher's matching strategy.
boolean	matchStart(String pattern, String path) Match the given path against the corresponding part of the given pattern, according to this PathMatcher's matching strategy.

Method Detail

isPattern

boolean isPattern(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.

Parameters:

path - the path String to check

Returns:

true if the given path represents a pattern

match

boolean match(String pattern,
              String path)

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

Parameters:

pattern - the pattern to match against

path - the path String to test

Returns:

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

matchStart

boolean matchStart(String pattern,
                   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.

Parameters:

pattern - the pattern to match against

path - the path String to test

Returns:

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

extractPathWithinPattern

String extractPathWithinPattern(String pattern,
                                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.

Parameters:

pattern - the path pattern

path - the full path to introspect

Returns:

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