The aim of this interceptor is to set values in the stack/action based on cookie name/value of interest.
If an asterisk is present in cookiesName parameter, it will be assume that all cookies name are to be injected into struts' action, even though cookiesName is comma-separated by other values, e.g. (cookie1,*,cookie2).
If cookiesName is left empty it will assume that no cookie will be injected into Struts' action.
If an asterisk is present in cookiesValue parameter, it will assume that all cookies name irrespective of its value will be injected into Struts' action so long as the cookie name matches those specified in cookiesName parameter.
If cookiesValue is left empty it will assume that all cookie that match the cookieName parameter will be injected into Struts' action.
The action could implement CookiesAware in order to have a Map of filtered cookies set into it.
Parameters
- cookiesName (mandatory) - Name of cookies to be injected into the action. If more than one cookie name is desired it could be comma-separated. If all cookies name is desired, it could simply be *, an asterik. When many cookies name are comma-separated either of the cookie that match the name in the comma-separated list will be qualified.
- cookiesValue (mandatory) - Value of cookies that if its name matches cookieName attribute and its value matched this, will be injected into Struts' action. If more than one cookie name is desired it could be comma-separated. If left empty, it will assume any value would be ok. If more than one value is specified (comma-separated) it will assume a match if either value is matched.
- acceptCookieNames (optional) - Pattern used to check if name of cookie matches the provided patter, to
Extending the Interceptor
- populateCookieValueIntoStack - this method will decide if this cookie value is qualified to be populated into the value stack (hence into the action itself)
- injectIntoCookiesAwareAction - this method will inject selected cookies (as a java.util.Map) into action that implements CookiesAware.
