My Controller File has
#Controller("resources")
public class Resources {
#RequestMapping(value = "/resources/{name}", method = RequestMethod.GET)
public Map getResource(#PathVariable String name) {
return new HashMap();
}
}
But whenever i try to access /server/resources/myfilename.html
Server throws 404 saying /server/WEB-INF/jsp/resources/myfilename.jsp is not found.
But it should load /server/WEB-INF/jsp/resources.jsp as im using BeanNameViewResolver. Please help.

What you get:
Controller return a null view name, so DefaultRequestToViewNameTranslator generates one from URI = path from servlet path without slashes and filename extension: resources/myfilename
BeanNameViewResolver try to get a View from context named resources/myfilename, seem that fails and chain to next ViewResolver
InternalResourceViewResolver return a JstlView pointing to jsp prefix + viewName + suffix = /WEB-INF/jsp/resources/myfilename.jsp
So BeanNameViewResolver seems that don't resolve the view and the return of InternalResourceViewResolver is the expected one.
What you want (I think)
You want to remove the filename from the default view name, not only the extension.
Implements a RequestToViewNameTranslator and declare it in the DispatcherServlet context with name viewNameTranslator.
For example:
public class StripFileNameViewNameTranslator extends DefaultRequestToViewNameTranslator {
#Override
protected String transformPath(String lookupPath) {
String path = super.transformPath(lookupPath);
return StringUtils.substringBeforeLast(path, "/");
}
}
