本项目基于spring boot 多模块

注意spring -boot、spring-cloud、spring-cloud-alibaba的版本兼容性

1.1、父级pom依赖

<properties>
    <spring-boot.version>2.7.18</spring-boot.version>
    <spring.cloud.version>2021.0.1</spring.cloud.version>
    <spring.cloud.alibaba.version>2021.0.1.0</spring.cloud.alibaba.version>
</properties>


<dependencyManagement>
        <dependencies>
           <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>
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring.cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            
            <!-- SpringBoot 依赖配置 -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring-boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

1.2、子模块pom依赖

 <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
        <dependency>
          <groupId>com.alibaba.cloud</groupId>
          <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>                        
    </dependencies>

2、子模块配置文件

必须在resources下使用bootstrap.yml 文件

确保namespace、group、cluster一致性

server:
  port: 8001
  servlet:
    context-path: /user
spring:
  application:
    name: user
  profiles:
    # 环境配置 需要在nacos管理端添加配置文件
    active: standard
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.20.113:8848
        namespace: cedb1f46-d9ae-43b1-99db-39b245152543
        group: DEFAULT_GROUP
      # 动态读取nacos服务端配置
      config:
        username: nacos
        password: nacos
        server-addr: 192.168.20.113:8848
        file-extension: yaml
        namespace: cedb1f46-d9ae-43b1-99db-39b245152543
        group: DEFAULT_GROUP
        refresh: true
        # 共享配置
        shared-configs:
          - application-druid.${spring.cloud.nacos.config.file-extension}

3、开启nacos

启动类添加注解@EnableDiscoveryClient

@EnableAsync
@EnableScheduling
@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class })
@EnableDiscoveryClient
public class MoodSysApplication{
    
}
