&lt;p>配置中心 (config-center) 在 Dubbo 中可承担两类职责：&lt;/p>
&lt;ol>
&lt;li>&lt;a href="../config/principle/#33-%E5%A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE">外部化配置&lt;/a>：启动配置的集中式存储 （简单理解为 dubbo.properties 的外部化存储）。&lt;/li>
&lt;li>流量治理规则存储&lt;/li>
&lt;/ol>
&lt;p>请参考具体扩展实现了解如何启用配置中心。&lt;/p>
&lt;p>值得注意的是 Dubbo 动态配置中心定义了两个不同层次的隔离选项，分别是 namespace 和 group。&lt;/p>
&lt;ul>
&lt;li>namespace - 配置命名空间，默认值 &lt;code>dubbo&lt;/code>。命名空间通常用于多租户隔离，即对不同用户、不同环境或完全不关联的一系列配置进行逻辑隔离，区别于物理隔离的点是不同的命名空间使用的还是同一物理集群。&lt;/li>
&lt;li>group - 配置分组，默认值 &lt;code>dubbo&lt;/code>。&lt;code>group&lt;/code> 通常用于归类一组相同类型/目的的配置项，是对 &lt;code>namespace&lt;/code> 下配置项的进一步隔离。&lt;/li>
&lt;/ul>
&lt;p>参考 &lt;a href="../config/properties/#config-center">配置说明 - 配置项手册&lt;/a> 了解 namespace 和 group 之外 config-center 开放的更多配置项。&lt;/p>
&lt;blockquote>
&lt;p>为了兼容 2.6.x 版本配置，在使用 Zookeeper 作为注册中心，且没有显式配置配置中心的情况下，Dubbo 框架会默认将此 Zookeeper 用作配置中心，但将只作服务治理用途。&lt;/p>

&lt;p>dubbo3.0支持native-image文档&lt;/p>
&lt;h2 id="概述">概述&lt;/h2>
&lt;p>本文档将介绍将dubbo3.0项目接入GraalVM，进行native-image编译为二进制的流程。&lt;/p>
&lt;p>关于GraalVm的更多信息可以阅读 &lt;a href="https://www.graalvm.org/docs/getting-started/container-images/">https://www.graalvm.org/docs/getting-started/container-images/&lt;/a> 此文档。&lt;/p>
&lt;h2 id="使用样例">使用样例&lt;/h2>
&lt;p>在编译我们的dubbo项目之前，需要确保我们正基于graalVm的环境。&lt;/p>
&lt;ol>
&lt;li>安装GraalVM&lt;/li>
&lt;/ol>
&lt;p>进入https://www.graalvm.org/ 官网根据自己的系统选取最新版本安装：&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/graalvmgw.jpg" alt="img">&lt;/p>
&lt;p>安装完成后，修改配置JAVA_HOME的路径，生效后查看本地jdk可以看到如下：&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/graalvm_env.jpg" alt="img">
这里我们使用的基于jdk1.8版本的GraalVM。&lt;/p>
&lt;ul>
&lt;li>安装native-image，只需执行gu install native-image即可。&lt;/li>
&lt;/ul>
&lt;ol>
&lt;li>拉取dubbo代码，切换到&lt;a href="https://github.com/apache/dubbo">apache:3.0&lt;/a>分支。&lt;/li>
&lt;li>手动执行生成SPI代码。&lt;/li>
&lt;/ol>
&lt;p>由于目前编译native-image不支持代码动态生成编译，所以有关代码动态生成的部分需要我们手动先生成，这里提供了工具函数：&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/code_generator.jpg" alt="img">
执行CodeGenerator即可在dubbo-native模块下生成SPI代码。&lt;/p>
&lt;ol>
&lt;li>在根目录下执行install&lt;/li>
&lt;/ol>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-go" data-lang="go">&lt;span style="display:flex;">&lt;span>MacdeMacBook&lt;span style="color:#719e07">-&lt;/span>pro&lt;span style="color:#719e07">-&lt;/span>&lt;span style="color:#2aa198">3&lt;/span>:incubator&lt;span style="color:#719e07">-&lt;/span>dubbo mac$ pwd
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>&lt;span style="color:#719e07">/&lt;/span>Users&lt;span style="color:#719e07">/&lt;/span>mac&lt;span style="color:#719e07">/&lt;/span>Documents&lt;span style="color:#719e07">/&lt;/span>Mi&lt;span style="color:#719e07">/&lt;/span>project&lt;span style="color:#719e07">/&lt;/span>incubator&lt;span style="color:#719e07">-&lt;/span>dubbo
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>MacdeMacBook&lt;span style="color:#719e07">-&lt;/span>pro&lt;span style="color:#719e07">-&lt;/span>&lt;span style="color:#2aa198">3&lt;/span>:incubator&lt;span style="color:#719e07">-&lt;/span>dubbo mac$ mvn clean &lt;span style="color:#719e07">package&lt;/span> install &lt;span style="color:#719e07">-&lt;/span>Dmaven.test.skip=&lt;span style="color:#cb4b16">true&lt;/span>
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;ol>
&lt;li>编译demo项目&lt;/li>
&lt;/ol>
&lt;p>这里我们提供了可直接进行编译的示例项目，dubbo-demo/dubbo-demo-native。上面步骤install完成后，先到dubbo-demo-native的provider下，执行native-image编译：&lt;/p>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-go" data-lang="go">&lt;span style="display:flex;">&lt;span> mvn clean &lt;span style="color:#719e07">package&lt;/span> &lt;span style="color:#719e07">-&lt;/span>P native &lt;span style="color:#719e07">-&lt;/span>Dmaven.test.skip=&lt;span style="color:#cb4b16">true&lt;/span>
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;p>这里由于我们在maven中引入了native-image插件，所以直接-P native即可执行该插件。&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/native_image_build.jpg" alt="img">
编译成功后可以在target下看到已经生成的二进制文件，本地启动一个zookeeper，直接执行该二进制，可见启动成功如下：&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/run_provider.jpg" alt="img">
consumer端同样执行编译，在consumer的target下也会生成二进制文件：demo-native-consumer,执行该二进制可以看到调用结果如下：&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/run_consumer.jpg" alt="img">&lt;/p>
&lt;h3 id="具体步骤">具体步骤&lt;/h3>
&lt;p>实际上在这个demo下我们做了一些工作来确保项目可以编译执行，主要有以下几个步骤&lt;/p>
&lt;ul>
&lt;li>引入dubbo-native依赖&lt;/li>
&lt;/ul>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-fallback" data-lang="fallback">&lt;span style="display:flex;">&lt;span>&amp;lt;dependency&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;groupId&amp;gt;org.apache.dubbo&amp;lt;/groupId&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;artifactId&amp;gt;dubbo-native&amp;lt;/artifactId&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;version&amp;gt;${project.version}&amp;lt;/version&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>&amp;lt;/dependency&amp;gt;
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;p>该模块下有我们生成的SPI代码。&lt;/p>
&lt;ul>
&lt;li>引入native-image插件&lt;/li>
&lt;/ul>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-fallback" data-lang="fallback">&lt;span style="display:flex;">&lt;span>&amp;lt;plugin&amp;gt;

&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;groupId&amp;gt;org.graalvm.nativeimage&amp;lt;/groupId&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;artifactId&amp;gt;native-image-maven-plugin&amp;lt;/artifactId&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;version&amp;gt;21.0.0.2&amp;lt;/version&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;executions&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;execution&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;goals&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;goal&amp;gt;native-image&amp;lt;/goal&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;/goals&amp;gt;
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span>
&lt;/span>&lt;/span>&lt;span style="display:flex;">&lt;span> &amp;lt;phase&amp;gt;package&amp;lt;/phase&amp;gt;

&lt;ul>
&lt;li>挂载native-image-agent&lt;/li>
&lt;/ul>
&lt;p>由于我们需要将一些反射、JNI等类先指定出来，我们需要先使用该agent以正常方式运行一遍生成这些类的json形式的信息。&lt;/p>
&lt;p>在启动参数中添加：&lt;/p>
&lt;div class="highlight">&lt;pre tabindex="0" style="color:#93a1a1;background-color:#002b36;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-fallback" data-lang="fallback">&lt;span style="display:flex;">&lt;span>-agentlib:native-image-agent=config-output-dir=/tmp/config/,config-write-period-secs=300,config-write-initial-delay-secs=5
&lt;/span>&lt;/span>&lt;/code>&lt;/pre>&lt;/div>&lt;p>以正常方式启动，在项目的resources下建立文件夹META-INF.native-image，把在本地目录中生成的文件粘进去：&lt;/p>
&lt;p>&lt;img src="https://dubbo.apache.org/imgs/blog/dubbo3.0-graalvm-support/resources.jpg" alt="img">
（可能会有缺漏没有生成的类信息，需要根据编译或运行时的报错信息手动添加。）&lt;/p>
