Struts2 filter to solve a simple way of conflict

sponsored links
struts2 filter using FilterDispatcher the url, the default is that all url are filtered, but some of the project is not want to use struts2 url filtering, online search a number of methods

1. Modify web.xml file.


<filter-name> struts2 </ filter-name>

<url-pattern> *. action </ url-pattern>

</ Filter-mapping>

Only to add a filter on. Action suffix of the path is valid, if you need to intercept. Jsp, *. jsp on the line together.

However, whether this extension if the url (eg / demo /) can not be filtered

2. Modify struts2 core jar file in the

The struts.action.extension = action,,

To struts.action.extension = action, do, jsp,

But I did not change the results after that, I do not know why

3. StrutsPrepareAndExecuteFilter customize a succession of filters will be configured into their own custom filters. (Recommended for this method)

public class ExtendStrutsFilter extends StrutsPrepareAndExecuteFilter {
        public void doFilter(ServletRequest req, ServletResponse res,FilterChain chain) throws IOException, ServletException {
                HttpServletRequest request = (HttpServletRequest) req;
                // Not filtered url, can add  
                if ("/demo/fileupload".equals(request.getRequestURI())) {
                        //System.out.println(" Use custom filters  ");
                        chain.doFilter(req, res);
                        //System.out.println(" Use the default filter  ");
                        super.doFilter(req, res, chain);

Modify web.xml

<!-- sturts2 Filter   -->
                <!--  Replaced by your own filters   -->
