restlet中如果访问资源路径不存在如何进行默认处理

import org.restlet.Request;  
import org.restlet.Response;  
import org.restlet.data.Status;  
import org.restlet.representation.Representation;  
import org.restlet.representation.StringRepresentation;  
import org.restlet.service.StatusService;  
  
public class MyDefaultResource extends StatusService{  
  
    /**当访问的资源不存在时默认由该资源进行处理*/  
    @Override  
    public Representation getRepresentation(Status status, Request request,  
            Response response) {  
        super.getRepresentation(status, request, response);  
         
        return new StringRepresentation(" 不起，您访问的资源不存在!" );  
    }  
      
}  

package com.zhongying.customer.application.bigUser;  
  
import org.restlet.Application;  
import org.restlet.Restlet;  
import org.restlet.routing.Router;  
  
import com.zhongying.customer.resource.bigUser.currentInUse.GetDefineDataServerResource;  
import com.zhongying.customer.resource.error.MyDefaultResource;  
  
 //为资源配置路径  
public class ServerApplication extends Application {  
      
    public ServerApplication() {  
        setStatusService(new MyDefaultResource());//当访问的资源不存在时默认由来处理  
    }  
      
    @Override  
    public Restlet createInboundRoot() {  
        Router router = new Router(this.getContext());  
        router.attach("/getData/{type}&{shopId}", GetDefineDataServerResource.class);  
        return router;  
    }  
}
