Struts2 filter to solve a simple way of conflict
Advertisements
1. Modify web.xml file.
<filter-mapping>
<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 default.properties
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 {
@Override
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);
}else{
//System.out.println(" Use the default filter ");
super.doFilter(req, res, chain);
}
}
}
Modify web.xml
<!-- sturts2 Filter -->
<filter>
<filter-name>struts2</filter-name>
<!-- Replaced by your own filters -->
<filter-class>
com.filter.ExtendStrutsFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
This method is successfully tested
