You can create and configure your own filter by doing following steps.

1) Create your class by implementing the filter interface and override its methods.

public class MyFilter implements javax.servlet.Filter{


public void destroy(){}
public void doFilter(Request, Response, FilterChain){//do what you want to filter
}
........
}

2) Now configure your filter in web.xml

  myFilter
  MyFilter

3) Now provide url mapping of the filter.

   myFilter
   *

4) Now restart your server and check all the web request will first come to MyFilter and then proceed to the respective controller.

Hopefully it will be the required answer.
