首先创建一个父模块（怎么创建应该就不用多说了吧，重点是依赖这些东西，我这里是大致拿出我其中的一个项目做例子）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <groupId>com.gq</groupId>
    <artifactId>Shopping</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <!-- 子模块 -->
    <modules>
<!--        通用模快，包含实体类，服务接口，工具类等等-->
        <module>shopping_common</module>

        <module>shopping_goods_service</module>
<!--        管理员管理网站操作的api-->
        <module>shopping_manager_api</module>
<!--        管理员模块-->
        <module>shopping_admin_service</module>

        <module>shopping_category_customer_api</module>

        <module>shopping_message_service</module>

        <module>shopping_user_service</module>
<!--        用户业务的api-->
        <module>shopping_user_customer_api</module>
    </modules>

</project>

（1）启动类

package com.gq.shopping_admin_service;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
@MapperScan("com.gq.shopping_admin_service.mapper")
@EnableDiscoveryClient
@EnableDubbo
@RefreshScope
public class ShoppingAdminServiceApplication {

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

    // 分页插件
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}

基本上都是这样创建的！
