+# Nacos Registry Center
+
+Nacos is a very important registry center for Dubbo ecosystem,
[`dubbo-registry-nacos`](https://github.com/apache/incubator-dubbo/tree/master/dubbo-registry/dubbo-registry-nacos)
is the implementation of Nacos integration to Nacos.
+
+
+
+## Prepare Work
+
+When you integrate
[`dubbo-registry-nacos`](https://github.com/apache/incubator-dubbo/tree/master/dubbo-registry/dubbo-registry-nacos)
into your Dubbo project, please Make sure the Nacos service is started in the
background. If you are not familiar with the basic use of Nacos, you can refer
to [Nacos Quick Start](https://nacos.io/en-us/docs/quick-start.html). It is
recommended to use the version equal or above Nacos `1.0.0`.
+
+
+## Quick Start
+
+The steps for Dubbo to integrate Nacos as a registry center are very simple.
The general steps can be divided into "add Maven dependencies" and "configure
registry center".
+
+
+### Add Maven Dependencies
+
+First, you need to add the `dubbo-registry-nacos` Maven dependency to your
project's `pom.xml` file, and we strongly recommend that you use Dubbo `2.6.5`:
+
+
+```xml
+<dependencies>
+
+ ...
+
+ <!-- Dubbo Nacos registry dependency -->
+ <dependency>
+ <groupId>com.alibaba</groupId>
+ <artifactId>dubbo-registry-nacos</artifactId>
+ <version>0.0.2</version>
+ </dependency>
+
+ <!-- Keep latest Nacos client version -->
+ <dependency>
+ <groupId>com.alibaba.nacos</groupId>
+ <artifactId>nacos-client</artifactId>
+ <version>[0.6.1,)</version>
+ </dependency>
+
+ <!-- Dubbo dependency -->
+ <dependency>
+ <groupId>com.alibaba</groupId>
+ <artifactId>dubbo</artifactId>
+ <version>2.6.5</version>
+ </dependency>
+
+ <!-- Alibaba Spring Context extension -->
+ <dependency>
+ <groupId>com.alibaba.spring</groupId>
+ <artifactId>spring-context-support</artifactId>
+ <version>1.0.2</version>
+ </dependency>
+
+ ...
+
+</dependencies>
+```
+
+When you add `dubbo-registry-nacos` to your project, you don't need to
explicitly program the service discovery and registration logic. The actual
implementation is provided by the three-party package.
+
+
+### Configure Registry Center
+
+Assuming your Dubbo app uses the Spring Framework assembly, there are two
configuration options available: [Dubbo Spring Externalization
Configuration](https://mercyblitz.github.io/2018/01/18/Dubbo-%E5%
A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE/) and the Spring XML configuration
file.
+
+
+### [Dubbo Spring Externalization
Configuration](https://mercyblitz.github.io/2018/01/18/Dubbo-%E5%A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE/)
+
+
+The Dubbo Spring externalization configuration is a new feature introduced by
Dubbo `2.5.8` that automatically generates and binds Dubbo configuration beans
through the Spring `Environment` property, simplifying configuration and
lowering the microservice development threshold.
+
+Assuming your Nacos Server is also running on server `10.20.153.10` and using
the default Nacos service port `8848`, you only need to adjust the
`dubbo.registry.address` property as follows:
+
+
+```properties
+## Other properties remain unchanged
+
+## Nacos registry address
+dubbo.registry.address = nacos://10.20.153.10:8848
+...
+```
+
+Then, restart your Dubbo app, Dubbo's service provider and consumer
information can be displayed on the Nacos console:
+
+
+
+
+As shown in the figure, the information whose service name prefix is
`providers:` is the meta information of the service provider, and the
`consumers:` represents the meta information of the service consumer. Click on
"**Details**" to view service status details:
+
+
+
+
+
+If you are using the Spring XML configuration file to assemble the Dubbo
registry, please refer to the next section.
+
+
+
+### Spring XML Configuration File
+
+Similar to [Dubbo Spring Externalization
Configuration](https://mercyblitz.github.io/2018/01/18/Dubbo-%E5%A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE/),
just adjust the `address` attribute to configure:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<beans xmlns="http://www.springframework.org/schema/beans";
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
+ xmlns:dubbo="http://dubbo.apache.org/schema/dubbo";
+ xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://dubbo.apache.org/schema/dubbo
http://dubbo.apache.org/schema/dubbo/dubbo.xsd";>
+
+ <!-- Provider application information for calculating dependencies -->
+ <dubbo:application name="dubbo-provider-xml-demo" />
+
+ <!-- Use Nacos as Registry Center -->
+ <dubbo:registry address="nacos://10.20.153.10:8848" />
+ ...
+</beans>
+```
+
+
+After restarting the Dubbo app, you can also find that the registration
meta-information of the service provider and consumer is presented on the Nacos
console:

+# Nacos 注册中心
+
+Nacos 作为 Dubbo 生态系统中重要的注册中心实现，其中
[`dubbo-registry-nacos`](https://github.com/apache/incubator-dubbo/tree/master/dubbo-registry/dubbo-registry-nacos)
则是 Dubbo 融合 Nacos 注册中心的实现。
+
+
+
+## 预备工作
+
+当您将
[`dubbo-registry-nacos`](https://github.com/apache/incubator-dubbo/tree/master/dubbo-registry/dubbo-registry-nacos)
整合到您的 Dubbo 工程之前，请确保后台已经启动 Nacos 服务。如果您尚且不熟悉 Nacos 的基本使用的话，可先行参考 [Nacos
快速入门](https://nacos.io/en-us/docs/quick-start.html)。建议使用 Nacos `1.0.0` 及以上的版本。
+
+
+
+## 快速上手
+
+Dubbo 融合 Nacos 成为注册中心的操作步骤非常简单，大致步骤可分为“增加 Maven 依赖”以及“配置注册中心“。
+
+
+### 增加 Maven 依赖
+
+首先，您需要 `dubbo-registry-nacos` 的 Maven 依赖添加到您的项目中 `pom.xml` 文件中，并且强烈地推荐您使用
Dubbo `2.6.5`：
+
+```xml
+<dependencies>
+
+ ...
+
+ <!-- Dubbo Nacos registry dependency -->
+ <dependency>
+ <groupId>com.alibaba</groupId>
+ <artifactId>dubbo-registry-nacos</artifactId>
+ <version>0.0.2</version>
+ </dependency>
+
+ <!-- Keep latest Nacos client version -->
+ <dependency>
+ <groupId>com.alibaba.nacos</groupId>
+ <artifactId>nacos-client</artifactId>
+ <version>[0.6.1,)</version>
+ </dependency>
+
+ <!-- Dubbo dependency -->
+ <dependency>
+ <groupId>com.alibaba</groupId>
+ <artifactId>dubbo</artifactId>
+ <version>2.6.5</version>
+ </dependency>
+
+ <!-- Alibaba Spring Context extension -->
+ <dependency>
+ <groupId>com.alibaba.spring</groupId>
+ <artifactId>spring-context-support</artifactId>
+ <version>1.0.2</version>
+ </dependency>
+
+ ...
+
+</dependencies>
+```
+
+
+
+当项目中添加 `dubbo-registry-nacos` 后，您无需显示地编程实现服务发现和注册逻辑，实际实现由该三方包提供，接下来配置 Naocs
注册中心。
+
+
+
+### 配置注册中心
+
+假设您 Dubbo 应用使用 Spring Framework 装配，将有两种配置方法可选，分别为：[Dubbo Spring
外部化配置](https://mercyblitz.github.io/2018/01/18/Dubbo-%E5%A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE/)以及
Spring XML 配置文件以及 ，推荐前者。
+
+
+### [Dubbo Spring
外部化配置](https://mercyblitz.github.io/2018/01/18/Dubbo-%E5%A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE/)
+
+Dubbo Spring 外部化配置是由 Dubbo `2.5.8` 引入的新特性，可通过 Spring `Environment` 属性自动地生成并绑定
Dubbo 配置 Bean，实现配置简化，并且降低微服务开发门槛。
+
+假设您的 Nacos Server 同样运行在服务器 `10.20.153.10` 上，并使用默认 Nacos 服务端口 `8848`，您只需将
`dubbo.registry.address` 属性调整如下：
+
+
+
+```properties
+## 其他属性保持不变
+
+## Nacos registry address
+dubbo.registry.address = nacos://10.20.153.10:8848
+...
+```
+
+
+
+随后，重启您的 Dubbo 应用，Dubbo 的服务提供和消费信息在 Nacos 控制台中可以显示：
+
+
+
+
+
+如图所示，服务名前缀为 `providers:` 的信息为服务提供者的元信息，`consumers:`
则代表服务消费者的元信息。点击“**详情**”可查看服务状态详情：
+
+
+
+
+
+如果您正在使用 Spring XML 配置文件装配 Dubbo 注册中心的话，请参考下一节。
+
+
+
+### Spring XML 配置文件
+
+与 [Dubbo Spring
外部化配置](https://mercyblitz.github.io/2018/01/18/Dubbo-%E5%A4%96%E9%83%A8%E5%8C%96%E9%85%8D%E7%BD%AE/)
配置类似，只需要调整 `address` 属性配置即可：
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<beans xmlns="http://www.springframework.org/schema/beans";
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
+ xmlns:dubbo="http://dubbo.apache.org/schema/dubbo";
+ xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://dubbo.apache.org/schema/dubbo
http://dubbo.apache.org/schema/dubbo/dubbo.xsd";>
+
+ <!-- 提供方应用信息，用于计算依赖关系 -->
+ <dubbo:application name="dubbo-provider-xml-demo" />
+
+ <!-- 使用 Nacos 注册中心 -->
+ <dubbo:registry address="nacos://10.20.153.10:8848" />
+ ...
+</beans>
+```
+
+
+
+重启 Dubbo 应用后，您同样也能发现服务提供方和消费方的注册元信息呈现在 Nacos 控制台中：
