AEM过滤器未被调用

Question

我编写了一个AEM过滤器，但没有被调用。     我们是否必须提供一些配置，除了班级以外？     下面是结构，那里有什么不对吗？

@SlingFilter(label = "ABC", description = "abc", metatype = false, generateComponent = false,
        generateService = true, // True; required for Sling Filters
        order = -8642, //lowest order as per my application
        scope = SlingFilterScope.REQUEST) 
@Properties({ @Property(label = "Vendor", name = "service.vendor", value = "abc", propertyPrivate = true) })
public class CoursePageFilter implements Filter {
    protected Logger log = LoggerFactory.getLogger(getClass());
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {      
        final SlingHttpServletResponse slingResponse = (SlingHttpServletResponse) response;
        final SlingHttpServletRequest slingRequest = (SlingHttpServletRequest) request;
        final Resource resource = slingRequest.getResource();
        String curPageName = resource.getPath();
        if (resource.getPath().startsWith("/xyz")) {
                RequestDispatcher dispatch = slingRequest.getRequestDispatcher("/abc.html");
                dispatch.forward(slingRequest, slingResponse);
                return;
        }
        // to proceed with the rest of the Filter chain     
        chain.doFilter(request, response);
    }
}
