| Leveraging the Restlet Routing System for Your Java Web Services
As Restlet applications have multiple important purposes,nike football, it is essential to understand how they are structured and then used at runtime by Restlet projects. In Figure 1, we illustrate their overall design into three concentric layers,ed hardy online, from the most generic and reusable on the edge to the most specific in the center. An application can handle both inbound server calls and outbound client calls, which are depicted using arrows. Inbound and Outbound Calls in Restlet Applications An inbound call first goes though a service filtering layer, which is common to all resources contained in the application. This layer can handle things such as automatic decoding of compressed representations or support for partial representations. Then, the call goes through a user routing layer, where you will be able to do your own filtering, for example, for authentication purpose and to route the request to its target resource, typically based on its URI. Finally, the call can reach the resource handling layer, where a target resource will handle the request and reply with a response that will return to the original client, following the same path. This request processing flow that we summarized is followed by a single Java thread in charge of the given call. In addition, client calls can be initiated by applications, typically, while handling server calls inside server resources, by creating client resources. A client resource sends a request through the upper layers, before it reaches the target resource (typically on a remote host), and finally comes back with a response. The user routing layer will have a chance to filter or dispatch the request,nike air max 2, for example, to handle automatic authentication, while the upper service filtering layer will be able to provide services such as automatic decompression of representations received in responses. The Restlet Routing System The user routing layer can be pretty limited, providing just a simple Restlet subclass that traces incoming calls. How can you build a filter that blocks some IP addresses or route calls to target server resource based on their URI? In this article we will introduce you to the Restlet routing system and answer the above questions. We will especially present Restlet filters and routers which are two key elements of this routing system, the first one facilitating the pre-processing and post-processing of calls,cheapest abercrombie & fitch, the second one allowing the dispatching of calls to one of the several target routes available, typically based on the target URI of the routed call.
