Util. The ServiceLoader</code>, namely extension in the jar package <code>meta-inf/services /</code> directory placed with interface of text files, with the same content for interface implementation class name, multiple separate implementation class name with a newline.Need to expand Dubbo agreement, for example, simply by XXX. Placed in a jar file: <code>meta-inf/services/com. Alibaba. Dubbo. RPC. Protocol</code>, contents for <code>com. Alibaba. XXX. XxxProtocol</code>.Dubbo by ServiceLoader scanning to all Protocol implementation.</p><p>All plug-in and agreed, must be marked with: <code>@ the Extension</code> (" name “), as the identity of the name, after loading is used to configure option.</p><h2 id=step-2-each-extension-point-encapsulate-a-change-factor-only-to-maximize-reuse>Step 2 each extension point encapsulate a change factor, only to maximize reuse</h2><p>Each extension point implementers, usually only care about one thing, now the extension points, is not entirely separate.Such as: Failover, the Route, LoadBalance, Directory not completely separate, all written by RoutingInvokerGroup died.</p><p>Again, for example, protocol extension, the extension may just want to replace the serialization way, or just replace transmission mode, and Remoting and Http can also reuse serialization, etc.In this way, the need for transport, the client, the server implementation, protocol parsing, data serialization, allow different extension point.</p><p>After break up, the design is as follows:</p><p><img src=/imgs/dev/design-step2.png alt=design-step-2></p><h2 id=step-3-the-entire-pipeline-design-logic-framework-itself-are-implemented-using-cross-section-intercept>Step 3, the entire pipeline design, logic framework itself, are implemented using cross section intercept</h2><p>Now a lot of logic, are placed in the base class implementation, then by the method of template back to the realization of the tone categories, including: local, mock, generic, echo, token, accesslog, monitor, count, limit, etc., can use the Filter to realize all split, each function is called a ring on the chain.Such as: (the base class template method)</p><div class=highlight><pre tabindex=0 style=color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-java data-lang=java><span style=display:flex><span><span style=color:#268bd2>public</span> <span style=color:#268bd2>abstract</span> AbstractInvoker <span style=color:#268bd2>implements</span> Invoker { |
