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：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

  32.             <scope>provided</scope>
  33.         </dependency>
  34.     </dependencies>
  36.     <!-- 维护依赖   -->

  54.             </dependency>
  55.         </dependencies>
  56.     </dependencyManagement>
  58. </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：

  1. <?xml version="1.0" encoding="UTF-8"?>
  3. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  5.   <modelVersion>4.0.0</modelVersion>
  7.   <groupId>com.hwadee.springcloud</groupId>
  8.   <artifactId>springcloud-api</artifactId>
  9.   <version>0.0.1-SNAPSHOT</version>
  11.   <parent>
  12.     <groupId>com.hwadee.springcloud2022</groupId>
  13.     <artifactId>springcloudalibaba</artifactId>
  14.     <version>0.0.1-SNAPSHOT</version>
  15.   </parent>
  18.   <build>
  19.     <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
  20.       <plugins>
  21.         <!-- clean lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#clean_Lifecycle -->
  22.         <plugin>
  23.           <artifactId>maven-clean-plugin</artifactId>
  24.           <version>3.1.0</version>
  25.         </plugin>
  26.         <!-- default lifecycle, jar packaging: see https://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_jar_packaging -->
  27.         <plugin>
  28.           <artifactId>maven-resources-plugin</artifactId>
  29.           <version>3.0.2</version>
  30.         </plugin>
  31.         <plugin>
  32.           <artifactId>maven-compiler-plugin</artifactId>
  33.           <version>3.8.0</version>
  34.         </plugin>
  35.         <plugin>
  36.           <artifactId>maven-surefire-plugin</artifactId>
  37.           <version>2.22.1</version>
  38.         </plugin>
  39.         <plugin>
  40.           <artifactId>maven-jar-plugin</artifactId>
  41.           <version>3.0.2</version>
  42.         </plugin>
  43.         <plugin>
  44.           <artifactId>maven-install-plugin</artifactId>
  45.           <version>2.5.2</version>
  46.         </plugin>
  47.         <plugin>
  48.           <artifactId>maven-deploy-plugin</artifactId>
  49.           <version>2.8.2</version>
  50.         </plugin>
  51.         <!-- site lifecycle, see https://maven.apache.org/ref/current/maven-core/lifecycles.html#site_Lifecycle -->
  52.         <plugin>
  53.           <artifactId>maven-site-plugin</artifactId>
  54.           <version>3.7.1</version>
  55.         </plugin>
  56.         <plugin>
  57.           <artifactId>maven-project-info-reports-plugin</artifactId>
  58.           <version>3.0.0</version>
  59.         </plugin>
  60.       </plugins>
  61.     </pluginManagement>
  62.   </build>
  63. </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

  1. // 商品实体类
  2. @Data
  3. public class Product {
  4.     private Long id;
  5.     private String name;
  6.     private BigDecimal price;
  7. }

三、完善父工程 pom

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

  19.         <relativePath/>
  20.     </parent>
  22.     <properties>
  23.         <spring.cloud.version>2021.0.4</spring.cloud.version>

  51.                 <version>${spring.cloud.version}</version>
  52.                 <type>pom</type>
  53.                 <scope>import</scope>
  54.             </dependency>
  55.             <!-- 维护springcloudalibaba依赖 版本使用2021.0.4.0 -->
