Struts2 's Defaultactionmapper

Defaultactionmapper is the implementation class of Actionmapper

One usage is to parse the URL request and then encapsulate the information into a actionmapping, actionmapping corresponding action, such as the name,namespace,method of the action, etc.

Public actionmapping getmapping (httpservletrequest request, ConfigurationManager ConfigManager) {        actionmapping mapping = new actionmapping ();        String uri = Requestutils.geturi (request);        int Indexofsemicolon = Uri.indexof (";");        URI = (Indexofsemicolon >-1)? Uri.substring (0, Indexofsemicolon): URI;        URI = Dropextension (URI, mapping);        if (URI = = null) {            return null;        }        Parsenameandnamespace (URI, Mapping, ConfigManager);        Handlespecialparameters (request, mapping);        return Parseactionname (mapping);    }

Get URLs from HttpServletRequest, such as http://localhost:8080/project name/useraction.action

int Indexofsemicolon = Uri.indexof (";");

URI = (Indexofsemicolon >-1)? Uri.substring (0, Indexofsemicolon): URI;

These two sentences are fixed URL of the band, the Jsessionid can not find the bug, specifically do not understand
