Javadoc

Creates a filter chain for the given chainName with the specified chainDefinitionString.

Conventional Use

Because the FilterChainManager interface does not impose any restrictions on filter chain names, (it expects only Strings), a convenient convention is to make the chain name an actual URL path expression (such as an org.apache.shiro.util.AntPathMatcher). For example:

createChain(path_expression, path_specific_filter_chain_definition); This convention can be used by a FilterChainResolver to inspect request URL paths against the chain name (path) and, if a match is found, return the corresponding chain for runtime filtering.

Chain Definition Format

The chainDefinition method argument is expected to conform to the following format:

 
filter1[optional_config1], filter2[optional_config2], ..., filterN[optional_configN]

where

filterN is the name of a filter previously #addFilter(String,javax.servlet.Filter) with the manager, and
[optional_configN] is an optional bracketed string that has meaning for that particular filter for this particular chain

If the filter does not need specific config for that chain name/URL path, you may discard the brackets - that is, filterN[] just becomes filterN.

And because this method does create a chain, remember that order matters! The comma-delimited filter tokens in the chainDefinition specify the chain's execution order.

Examples

/account/** = authcBasic

This example says "Create a filter named ' /account/**' consisting of only the ' authcBasic' filter". Also because the authcBasic filter does not need any path-specific config, it doesn't have any config brackets [].

/remoting/** = authcBasic, roles[b2bClient], perms["remote:invoke:wan,lan"]

This example by contrast uses the 'roles' and 'perms' filters which do use bracket notation. This definition says:

Construct a filter chain named ' /remoting/**' which

ensures the user is first authenticated ( authcBasic) then
ensures that user has the b2bClient role, and then finally
ensures that they have the remote:invoke:lan,wan permission.

Note: because elements within brackets [ ] can be comma-delimited themselves, you must quote the internal bracket definition if commas are needed (the above example has 'lan,wan'). If we didn't do that, the parser would interpret the chain definition as four tokens:

authcBasic
roles[b2bclient]
perms[remote:invoke:lan
wan]

which is obviously incorrect. So remember to use quotes if your internal bracket definitions need to use commas.
