梦想不抛弃苦心追求的人，只要不停止追求，你们会沐浴在梦想的光辉之中。再美好的梦想与目标，再完美的计划和方案，如果不能尽快在行动中落实，最终只能是纸上谈兵，空想一番。只要瞄准了大方向，坚持不懈地做下去，才能够扫除挡在梦想前面的障碍，实现美好的人生蓝图。SpringCloudAlibaba项目搭建，希望对大家有帮助，欢迎收藏，转发！站点地址：www.bmabk.com，来源：原文

借助Spring Cloud Alibaba搭建微服务平台，参考官网文档https://github.com/alibaba/spring-cloud-alibaba
SpringCloudAlibaba与SpringCloud和SpringBoot存在毕业版本的依赖关系，最好使用对应的版本，否则可能会出现不兼容的情况等(毕业版本依赖关系)

1.1 搭建父项目

点击finsh后就创建了父项目，此时删除父项目中的src目录，再修改pom.xml文件如下(子项目中常用依赖统一在父项目中导入)：

1.2 搭建公用模块

公共项目提供数据库、缓存等基础配置和POJO实例
SpringCloudAlibaba项目搭建

其Pom文件如下，其中公用的依赖已经在父项目中引入，在子模块中只需要引入spring-boot-start的依赖即可

<?xml version="1.0" encoding="UTF-8"?>
<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">
    <parent>
        <artifactId>shop-public</artifactId>
        <groupId>com.lizhi</groupId>
        <version>1.0    </version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>shop-common</artifactId>

    <properties>
        <maven.compiler.source>11</maven.compiler.source>
        <maven.compiler.target>11</maven.compiler.target>
    </properties>

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql.connector.version}</version>
            <scope>runtime</scope>
        </dependency>

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>${alibaba.druid.version}</version>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>${mybatis.plus.version}</version>
        </dependency>
    </dependencies>

</project>

spring-boot-starter-jdbc主要提供了三个功能，第一个就是对数据源的装配，第二个就是提供一个JdbcTemplate简化使用，第三个就是事务。该依赖在mybatis-plus-boot-starter中已经引入

1.3 搭建用户模块

其pom文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<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">
    <parent>
        <artifactId>shop-public</artifactId>
        <groupId>com.lizhi</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>shop-user</artifactId>

    <properties>
        <maven.compiler.source>11</maven.compiler.source>
        <maven.compiler.target>11</maven.compiler.target>
    </properties>

    <dependencies>
        <dependency>
            <groupId>com.lizhi</groupId>
            <artifactId>shop-common</artifactId>
            <version>${project.version}</version>
        </dependency>

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

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

</project>

后面shop-order和shop-product模块的创建与shop-user一样，就不赘述了，最后形成的项目目录如下
