In terms of community activity, spring cloud is undoubtedly superior to Dubbo, which is a better choice for teams without a lot of energy and money to maintain this part of open source content.

可能说起来Dubbo，很多人都不陌生，这毕竟是一款从2012年就开始开源的Java RPC框架，中间由于各种各样的原因停止更新4年半的时间，中间只发过一个小版本修了一个小bug，甚至大家都以为这个项目已经死掉了，竟然又在2017年9月份恢复了更新，不可谓不神奇。网络上很多人都拿Dubbo和Spring Cloud做对比，可能在大家的心目中，这两个框架是可以画上等号的吧，后来在网络上有一个非常流行的表格，比较详细的对比了 Spring Cloud 和 Dubbo ，表格如下：以上列举了一些核心部件，当然这里需要申明一点，Dubbo对于上表中总结为“无”的组件不代表不能实现，而只是Dubbo框架自身不提供，需要另外整合以实现对应的功能，这样看起来确实Dubbo更像是Spring Cloud的一个子集。Dubbo 在国内拥有着巨大的用户群，大家希望在使用 Dubbo 的同时享受 Spring Cloud 的生态，出现各种各样的整合方案，但是因为服务中心的不同，各种整合方案并不是那么自然，直到 Spring Cloud Alibaba 这个项目出现，由官方提供了 Nacos 服务注册中心后，才将这个问题完美的解决。并且提供了 Dubbo 和 Spring Cloud 整合的方案，命名为： Dubbo Spring Cloud 。Dubbo Spring Cloud 构建在原生的 Spring Cloud 之上，其服务治理方面的能力可认为是 Spring Cloud Plus，不仅完全覆盖 Spring Cloud 原生特性，而且提供更为稳定和成熟的实现，特性比对如下表所示：而且Dubbo Spring Cloud 基于 Dubbo Spring Boot 2.7.1 和 Spring Cloud 2.x 开发，无论开发人员是 Dubbo 用户还是 Spring Cloud 用户，都能轻松地驾驭，并以接近“零”成本的代价使应用向上迁移。Dubbo Spring Cloud 致力于简化云原生开发成本，以达成提高研发效能以及提升应用性能等目的。在Spring Cloud构建的微服务系统中，大多数的开发者使用都是官方提供的Feign组件来进行内部服务通信，这种声明式的HTTP客户端使用起来非常的简洁、方便、优雅，但是有一点，在使用Feign消费服务的时候，相比较Dubbo这种RPC框架而言，性能堪忧。虽说在微服务架构中，会讲按照业务划分的微服务独立部署，并且运行在各自的进程中。微服务之间的通信更加倾向于使用HTTP这种简答的通信机制，大多数情况都会使用REST API。这种通信方式非常的简洁高效，并且和开发平台、语言无关，但是通常情况下，HTTP并不会开启KeepAlive功能，即当前连接为短连接，短连接的缺点是每次请求都需要建立TCP连接，这使得其效率变的相当低下。对外部提供REST API服务是一件非常好的事情，但是如果内部调用也是使用HTTP调用方式，就会显得显得性能低下，Spring Cloud默认使用的Feign组件进行内部服务调用就是使用的HTTP协议进行调用，这时，我们如果内部服务使用RPC调用，对外使用REST API，将会是一个非常不错的选择，恰巧，Dubbo Spring Cloud给了我们这种选择的实现方式。本小结将会以一个简单的入门案例，介绍一下在使用Nacos作为服务中心，使用Dubbo来实现服务提供方和服务消费方的案例。Nacos的安装、部署配置和使用已经在前面的章节介绍过了，这里不再赘述，如果还有不清楚的读者，请参考前面的Nacos系列文章：API模块，存放Dubbo服务接口和模型定义，非必要，这里创建仅为更好的代码重用以及接口、模型规格控制管理。代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_api/src/main/java/com/springcloud/dubbo_api/service/HelloService.java代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_provider/pom.xml代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_provider/src/main/java/com/springcloud/dubbo_provider/service/HelloServiceI.java配置文件 application.yml 需要将Java服务（本地）配置为 Dubbo 服务（远程）如下：代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_provider/src/main/resources/application.ymlDubbo Spring Cloud 继承了 Dubbo Spring Boot 的外部化配置特性，也可以通过标注 @DubboComponentScan 来实现基准包扫描。代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_provider/src/main/java/com/springcloud/dubbo_provider/DubboProviderApplication.java代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_consumer/pom.xml代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_consumer/src/main/resources/application.yml代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_consumer/src/main/java/com/springcloud/dubbo_consumer/controller/HelloController.java代码清单：Alibaba/dubbo-spring-cloud-demo/dubbo_consumer/src/main/java/com/springcloud/dubbo_consumer/DubboConsumerApplication.java启动子工程 dubbo_provider 和子工程 dubbo_consumer ，启动完成后，我们可以访问Nacos控制台的服务列表上看到两个服务，如图：

In addition, there are two versions, Chinese and English, which are easier for domestic developers to read, which is why Dubbo is more popular in China.Because spring cloud integrates a large number of components, the volume of documents is naturally much more than Dubbo, and the content of documents is relatively simple and clear, but more integration oriented, and more in-depth use methods still need to see the detailed documents of its integrated components. When other services are processing some businesses, they need to obtain user data of user services.6.

Features. Underneath, Spring Cloud Sleuth is a layer over a Tracer library named Brave. Dubbo, the core framework of Alibaba’s service-oriented governance, is widely used in Alibaba Group’s member sites. Then we’ll add the dependencies in the pom.xml.Before we move on, we need to add a version to the definitions: The recommended way of exposing the service is to use the There are two parts involved in the configuration: Dubbo and Spring Cloud.This is the same as the other Spring Boot application class:The only thing worth mentioning here is that we should start the Nacos service before this, so that the service can be discovered by Nacos.Similar to the service side configuration, we need to specify dependencies:The main difference from the service side is the client will be a Web Servlet application using Similar to the service side, there are two parts of configuration: Dubbo and Spring.here we specify the service to consume by binding dubbo.cloud.subscribed-services to spring-cloud-dubbo-server-sample.Since it is a Web application, the default port is Since this is a web client, we can use curl to try it out. Spring cloud vs. Dubbo. A circuit breaker is needed to handle the timeout and error of service call in time, so as to prevent the whole system from being paralyzed due to the problem of one of the services.7.

一、dubbo簡介. In another In this article, we’ll use a simple echo example to illustrate the steps to use Dubbo on Spring Cloud Alibaba.This interface will be exposed to the remote clients. dd, yyyy' }} {{ parent.linkDate | date:'MMM. Dubbo Spring Cloud is based on Dubbo Spring Boot 2.7.3[1] and Spring Cloud 2.x development, whether the developer is a Dubbo user or a Spring Cloud user.

Whether you are a Dubbo user trying to adapt to Spring Cloud Alibaba or vice versa, the experience should be seamless.Opinions expressed by DZone contributors are their own. Sleuth configures everything you need to get started. 前言 Through routing configuration, the gateway determines which service processes a URL request. Under the integration of spring source, a lot of compatibility tests have been done to ensure that the machine has a higher stability.

6.2. 简而言之，Dubbo确实类似于Spring Cloud的一个子集，Dubbo功能和文档完善，在国内有很多的成熟用户，然而鉴于Dubbo的社区现状（曾经长期停止维护，2017年7月31日团队又宣布重点维护），使用起来还是有一定的门槛。 Dubbo具有调度、发现、监控、治理等功能，支持相当丰富的服务治理能力。Dubbo架 … Posted by bitt3n on Wed, 17 Jun 2020 04:52:16 +0200 6.2 Features.

As for document quality, due to the fast iteration of spring cloud, there will inevitably be inconsistencies, so I think Dubbo is better in terms of quality.

Spring Cloud. A service registry is needed. If we run Or we can run the Java client to get the same result.Spring Cloud Alibaba now has two releases that have included Dubbo.
