简单构建一整套SpringCloud微服务框架Nacos、Seata、RocketMQ、Feign、GateWay、Graylog、docker、Sleuth、zipkin、Elasticsearch
以下是一个简化版的Spring Cloud Alibaba微服务架构示例,包含了Nacos作为服务注册与发现,Seata用于分布式事务管理,RocketMQ用于消息队列,以及Feign和Gateway用于服务间通信和路由。
- 创建一个Spring Boot项目作为parent pom,包含以下依赖:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.1.RELEASE</version>
<relativePath/>
</parent>
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Hoxton.SR5</spring-cloud.version>
<spring-cloud-alibaba.version>2.2.1.RELEASE</spring-cloud-alibaba.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>${spring-cloud-alibaba.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
- 创建微服务模块,例如
service-provider
,并添加以下依赖:
<dependencies>
<!-- Nacos Discovery -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<!-- Seata for distributed transaction -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
</dependency>
<!-- RocketMQ -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-rocketmq</artifactId>
</dependency>
<!-- Feign for service to service call -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
</dependencies>
- 在
service-provider
中配置Nacos作为服务注册中心,Seata作为分布式事务管理器,RocketMQ用于消息通信,并定义Feign客户端用于服务间调用。
