最基本的SpringCloud的搭建

对于springcloud而言，模块是按业务进行区分的；

父工程

依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>   
 <version>2.3.2.RELEASE</version>
    <relativePath/>
</parent>

           <!--           将创建时生成的dependencies中的依赖进行删除-->
<dependencies>
           <!--           springcloud依赖-->
<dependency>
 <groupId>org.springframework.cloud</groupId>  
             <artifactId>spring-cloud-dependencies</artifactId>          
     <version>Hoxton.SR8</version>
<type>pom</type>
<scope>import</scope>
</dependency>
 <!--           springcloud  alibaba 的父依赖-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>          
     <version>2.2.3.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>

子工程

依赖

<!--        nacos客戶端依賴  注意dependencyManagement-->
 <dependencyManagement>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>      
 </dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
 </dependencyManagement>

启动

@SpringBootApplication
@EnableDiscoveryClient //能够让注册中心能够发现，扫描到服务。
public class MycloudProducerApplication {

    public static void main(String[] args) {
        SpringApplication.run(MycloudProducerApplication.class);
    }
}

yml配置
