spring security filter chain patterns

1
votes

When using Spring Security you map a chain of filters to URL patters to specify how those URLs are secured. These patterns can contain wildcards such as

/foo/*/bar
/foo/**/bar

I couldn't find any docs for these wildcards, but my guess is that the first pattern would match

/foo/baz/bar

but not

/foo/baz/baz/bar

whereas the second pattern (/foo/**/bar) would match both of these

maybe this code will help:

You are correct in your assumption. The single wildcard * matches anything in that particular level of the url tree, whereas the double wildcard ** matches any string pattern.

So 

/foo/*/bar

Would match 

/foo/abc/bar and /foo/xyz/bar but not /foo/abc/xyz/bar

Whereas 

/foo/**/bar

Would match all of the above.
