Spring Filter not getting invoked

Question

I added a CORS filter to my application, but it does not seem to be executed (no prints).

The filter is this:

@Component
public class SimpleCORSFilter ex         


        

Answer 1

First, it is uncommon to name the Root Spring Container xml file servlet-context.xml. This name is normally used for the DispatcherServlet configuration when using spring-mvc. You'd better use applicationContext.xml.

But anyway, you should use a DelegatingProxyFilter to allow proper initialization of the spring filter :

<filter>
    <filter-name>simpleCORSFilter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>

The DelegatingProxyFilter will search in root context a bean named simpleCORSFilter and will delegate the doFilter method to it.
