ACEGI @ AntPathMatcher

classes extends AbstractFilterInvocationDefinitionSource will define useAntPath.if true ,it will use AntPathMatcher to compare the urls.
AntPathMatcher will first convert the url to array useing the DEFAULT_PATH_SEPARATOR("/"),then compare each elements in the array.

	String[] patDirs = StringUtils.tokenizeToStringArray(pattern, this.pathSeparator);
		String[] strDirs = StringUtils.tokenizeToStringArray(str, this.pathSeparator);

while (patIdxStart <= patIdxEnd && strIdxStart <= strIdxEnd) {
			String patDir = (String) patDirs[patIdxStart];
			if (patDir.equals("**")) {
				break;
			}
			if (!matchStrings(patDir, (String) strDirs[strIdxStart])) {
				return false;
			}
			patIdxStart++;
			strIdxStart++;
		}

it use *,?,/ as key symbol,so you should filter this symbols in the url.
