Using DelegatingFilterProxy with autowired dependency

[omanand]

Hi,

I have a filter defined in web.xml as

<filter>
        <filter-name>sampleSpringFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    
    <filter-mapping>
		<filter-name>sampleSpringFilter</filter-name>
		<url-pattern>/api/foo/*</url-pattern>
    </filter-mapping>

The class sampleSpringFilter is defined as:

@Component("sampleSpringFilter")
public class SampleSpringFilter implementes Filter
{

  @Inject
  private ITestService testService;

 @Override
	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException {
--
}
}

When I am trying to deploy my webapp in tomcat 7, application context is not able to find sampleSpringFilter.
I don't want to use xml based bean definition for sampleSpringFilter.

Please help me resolving this issue.

Please use [ code][/code ] tags when posting code/xml/stacktraces, that way it remains readable...

Only specifing the filter and adding @Component is pretty useless... If you don't scan for components (component-scanning) nothing is going to happen. Also the compoment has to be in the root context (ContextLoaderListener) and not in the child context (DispatcherServlet).

Thanks Marten. I had made a mistake of specifying component-scan in the child context (DispatcherServlet).
