javax.servlet.Filter for specific request methods

Is it possible to apply filters to every POST (or combination of HTTP actions) in the application or desired mapping?

Example web.xml:

<filter>
    <display-name>AccessFilter</display-name>
    <filter-name>AccessFilter</filter-name>
    <filter-class>foo.bar.AccessFilter</filter-class>
</filter>
    <filter-mapping>
    <filter-name>AccessFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

And I have a controller that maps the following URLs:

For example.

Could I apply this filter JUST to the URLs which are POSTs?

Motivation: Only let the owners of the resources modify them, but let everyone consume them.

Check for request method in Filter as shown below and do what ever you want to do.

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse,
        FilterChain filterChain) throws ServletException, IOException {
    HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;

    String method = httpServletRequest.getMethod(); //post or get

}
