          Spring Cloud  Alibaba基础环境搭建。

一、创建父工程

1.创建父工程

       创建父工程 Maven 项目 springcoudalibaba，并对 springcloud、springcloudalibaba、依赖维护，对springboot父项目继承。

• 维护springcloud依赖           2021.0.4
• 维护springcloudalibaba依赖    2021.0.4.0
• 继承springboot父项目          2.6.11 

 修改 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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.hwadee.springcloud2022</groupId>
    <artifactId>springcloudalibaba</artifactId>
    <packaging>pom</packaging>
    <version>0.0.1-SNAPSHOT</version>


    <!-- 继承springboot父项目 2.6.11   -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.11</version>
        <relativePath/>
    </parent>

    <properties>
        <spring.cloud.version>2021.0.4</spring.cloud.version>
        <spring.cloud.alibaba.version>2021.0.4.0</spring.cloud.alibaba.version>
        <lombok.version>1.18.24</lombok.version>
    </properties>

    <dependencies>
        <!-- 方便创建类的gettter setter -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>${lombok.version}</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>

    <!-- 维护依赖   -->
    <dependencyManagement>
        <dependencies>
            <!-- 维护springcloud依赖 版本使用2021.0.4 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring.cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!-- 维护springcloudalibaba依赖 版本使用2021.0.4.0 -->
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>${spring.cloud.alibaba.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

</project>

二、创建公共API

1、创建公共API

      创建项目 springcoudalibaba 的公共api子模块 springcloud-api，修改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">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.hwadee.springcloud</groupId>
  <artifactId>springcloud-api</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <parent>
    <groupId>com.hwadee.springcloud2022</groupId>
    <artifactId>springcloudalibaba</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>


  <build>
    <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
      <plugins>
        <!-- clean lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#clean_Lifecycle -->
        <plugin>
          <artifactId>maven-clean-plugin</artifactId>
          <version>3.1.0</version>
        </plugin>
        <!-- default lifecycle, jar packaging: see https://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_jar_packaging -->
        <plugin>
          <artifactId>maven-resources-plugin</artifactId>
          <version>3.0.2</version>
        </plugin>
        <plugin>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>3.8.0</version>
        </plugin>
        <plugin>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.22.1</version>
        </plugin>
        <plugin>
          <artifactId>maven-jar-plugin</artifactId>
          <version>3.0.2</version>
        </plugin>
        <plugin>
          <artifactId>maven-install-plugin</artifactId>
          <version>2.5.2</version>
        </plugin>
        <plugin>
          <artifactId>maven-deploy-plugin</artifactId>
          <version>2.8.2</version>
        </plugin>
        <!-- site lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#site_Lifecycle -->
        <plugin>
          <artifactId>maven-site-plugin</artifactId>
          <version>3.7.1</version>
        </plugin>
        <plugin>
          <artifactId>maven-project-info-reports-plugin</artifactId>
          <version>3.0.0</version>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
</project>

2、创建实体类及打包

     创建公共api中的实体类Product，并进行打包

// 商品实体类
@Data
public class Product {
    private Long id;
    private String name;
    private BigDecimal price;
}

三、完善父工程 pom

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.hwadee.springcloud2022</groupId>
    <artifactId>springcloudalibaba</artifactId>
    <packaging>pom</packaging>
    <version>0.0.1-SNAPSHOT</version>
    <modules>
        <module>springcloud-api</module>
    </modules>

    <!-- 继承springboot父项目 2.6.11   -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.11</version>
        <relativePath/>
    </parent>

    <properties>
        <spring.cloud.version>2021.0.4</spring.cloud.version>
        <spring.cloud.alibaba.version>2021.0.4.0</spring.cloud.alibaba.version>
        <lombok.version>1.18.24</lombok.version>
    </properties>

    <dependencies>
        <!-- 方便创建类的gettter setter -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>${lombok.version}</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>

    <!-- 维护依赖   -->
    <dependencyManagement>
        <dependencies>
            <!-- 管理公共api -->
            <dependency>
                <groupId>com.hwadee.springcloud</groupId>
                <artifactId>springcloud-api</artifactId>
                <version>0.0.1-SNAPSHOT</version>
            </dependency>
            <!-- 维护springcloud依赖 版本使用2021.0.4 -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring.cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!-- 维护springcloudalibaba依赖 版本使用2021.0.4.0 -->
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>${spring.cloud.alibaba.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
