By introducing the dubbo-proxy plugin, you can build a simpler and more efficient traffic link for the back-end system of Dubbo framework.</div><div class="td-byline mb-4"><time datetime=2022-01-18 class=text-muted>Tuesday, January 18, 2022</time></div><header class=article-meta></header><h2 id=background>Background</h2><p><a href=/en/>Apache Dubbo</a> is a MicroService development framework open sourced by Alibaba and donated to Apache, which provides two key capabilities of RPC communication and microservice governance. It has not only been validated by Ali’s massive traffic in e-commerce scenario, but also been widely implemented in domestic technology companies.</p><p>In practical application scenarios, Apache Dubbo is generally used as the implementation framework for RPC calls between back-end systems, and when HTTP interfaces need to be provided to the front-end, the Dubbo Service is packaged as an HTTP interface through a “glue layer” and then delivered to the front-end system.</p><p><a href=https://apisix.apache.org/>Apache APISIX</a> is the top open source project of Apache Software Foundation and the most active open source gateway project today. As a dynamic, real-time, high-performance open source API gateway, Apache APISIX provides rich traffic management features such as load balancing, dynamic upstream, grayscale publishing, service meltdown, authentication, observability, and more.</p><p>Benefiting from the advantages of Apache Dubbo application scenarios, Apache APISIX is based on the open source project tengine/mod_dubbo module to equip Apache Dubbo services with HTTP gateway capabilities. Dubbo Service can be easily published as an HTTP service via the dubbo-proxy plugin.</p><p><img src=/imgs/blog/apisix-plugin/1.png alt="Architecture Diagram"></p><h2 id=how-to-use>How to use</h2><h3 id=getting-started-installation-and-use>Getting Started: Installation and Use</h3><blockquote><p>Here we recommend using the Apache APISIX version 2.11 image for installation. This version of APISIX-Base has the Dubbo module compiled by default, so you can use the <code>dubbo-proxy</code> plugin directly.</p></blockquote><p>In the next steps, we will use the <a href=https://github.com/apache/dubbo-samples><code>dubbo-samples</code></a> project for a partial demonstration. This project is a demo application implemented using Apache Dubbo, and in this article we use one of the sub-modules as the Dubbo Provider.</p><p>Before we get into the action, let’s take a brief look at the definition, configuration, and implementation of the Dubbo interface.</p><h4 id=interface-implementation>Interface implementation</h4><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>interface</span> <span style=color:#268bd2>DemoService</span> { |

| :::</p><h3 id=advanced-complex-scenario-example>Advanced: Complex Scenario Example</h3><p>As you can see in the simple use case above, we do publish Dubbo Service as an HTTP service via Apache APISIX, but there are obvious limitations in its use. For example, the parameters and return values of the interface must be <code>Map<String, Object></code>.</p><p>So, how do you expose the HTTP service through Apache APISIX if there is an interface in your project that is already defined, but does not meet the above restrictions?</p><h4 id=operation-steps-1>Operation steps</h4><p>For the above scenario, we can use the HTTP Request Body to describe the Service and Method to be invoked and the corresponding parameters, and then use the reflection mechanism of Java to realize the invocation of the target method. Finally, the return value is serialized to JSON and written to the HTTP Response Body.</p><p>This will further enhance the “HTTP to Dubbo” capability of Apache APISIX and apply it to all existing Dubbo services. For details, see the following.</p><ol><li>Add a Dubbo Service for existing projects to handle HTTP to Dubbo conversions in a unified way.</li></ol><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>class</span> <span style=color:#268bd2>DubboInvocationParameter</span> { |
