| <p><strong>本文以实际项目和代码为示例，一步一步演示如何以最低成本实现 Apache Dubbo 体系与 Spring Cloud 体系的互通，进而实现不同微服务体系的混合部署、迁移等，帮助您解决实际架构及业务问题。</strong></p> |
| <h2 id="背景与目标">背景与目标</h2> |
| <p>如果你在微服务开发过程中正面临以下一些业务场景需要解决，那么这篇文章可以帮到您：</p> |
| <ul> |
| <li>您已经有一套基于 Dubbo 构建的微服务应用，这时你需要将部分服务通过 REST HTTP 的形式（非接口、方法模式）发布出去，供一些标准的 HTTP 端调用（如 Spring Cloud 客户端），整个过程最好是不用改代码，直接为写好的 Dubbo 服务加一些配置、注解就能实现。</li> |
| <li>您已经有一套基于 Spring Cloud 构建的微服务体系，而后又构建了一套 Dubbo 体系的微服务，你想两套体系共存，因此现在两边都需要调用到对方发布的服务。也就是 Dubbo 应用作为消费方要调用到 Spring Cloud 发布的 HTTP 接口，Dubbo 应用作为提供方还能发布 HTTP 接口给 Spring Cloud 调用</li> |
| <li>出于一些历史原因，你正规划从一个微服务体系迁移到另外一个微服务体系，前提条件是要保证中间过程的平滑迁移。</li> |
| </ul> |
| <p><img src="https://dubbo.apache.org/imgs/blog/2023/9/springcloud/img.png" alt="image.png"></p> |
| <p>对于以上几个场景，我们都可以借助 Dubbo3 内置的 REST 编程范式支持实现，这让 Dubbo 既可以作为消费方调用 HTTP 接口的服务，又可以作为提供方对外发布 REST 风格的 HTTP 服务，同时整个编码过程支持业界常用的 REST 编程范式（如 JAX-RS、Spring MVC 等），因此可以做到基本不改动任何代码的情况下实现 Dubbo 与 Spring Cloud 体系的互相调用。</p> |
| <ul> |
| <li>关于这一部分更多的设计与理论阐述请参见这里的 <a href="https://dubbo.apache.org/zh-cn/blog/2023/01/05/dubbo-%E8%BF%9E%E6%8E%A5%E5%BC%82%E6%9E%84%E5%BE%AE%E6%9C%8D%E5%8A%A1%E4%BD%93%E7%B3%BB-%E5%A4%9A%E5%8D%8F%E8%AE%AE%E5%A4%9A%E6%B3%A8%E5%86%8C%E4%B8%AD%E5%BF%83/">博客文章</a>。</li> |
| <li>关于 Dubbo REST 的更多配置方式请参见 <a href="https://dubbo.apache.org/zh-cn/overview/mannual/java-sdk/reference-manual/protocol/rest/">rest 使用参考手册</a></li> |
| </ul> |
| <h2 id="示例一dubbo-调用-spring-cloud">示例一：Dubbo 调用 Spring Cloud</h2> |
| <p>在已经有一套 Spring Cloud 微服务体系的情况下，演示如何使用 Dubbo 调用 Spring Cloud 服务（包含自动的地址发现与协议传输）。在注册中心方面，本示例使用 Nacos 作为注册中心，对于 Zookeeper、Consul 等两种体系都支持的注册中心同样适用。</p> |
| <p><img src="https://dubbo.apache.org/imgs/blog/2023/9/springcloud/img_1.png" alt="dubbo-call-spring-cloud"></p> |
| <p>设想你已经有一套 Spring Cloud 的微服务体系，现在我们将引入 Dubbo 框架，让 Dubbo 应用能够正常的调用到 Spring Cloud 发布的服务。本示例完整源码请参见 <a href="https://github.com/apache/dubbo-samples/tree/master/2-advanced/dubbo-samples-springcloud/dubbo-call-sc">samples/dubbo-call-sc</a>。</p> |
