1、建立springboot项目

• 这里springboot版本号随便选，其他都不要选，后面重现选springboot版本号
  

2、修改spring-cloud的pom.xml文件

2.1 去掉无关内容

<url/><licenses><license/></licenses><developers><developer/></developers><scm><connection/><developerConnection/><tag/><url/></scm>

2.2 标明为父工程

增加

 <packaging>pom</packaging>

2.3 springboot版本 3.2.0 + springcloud2023.0.3+springcloudalibaba2023.0.1.3

属性properties改为：

<properties><java.version>17</java.version><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><spring-cloud.version>2023.0.3</spring-cloud.version><spring-cloud-alibaba.version>2023.0.1.3</spring-cloud-alibaba.version></properties>

依赖管理声明版本为：

  <dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring-cloud-alibaba.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>

去掉依赖引入，因为是父工程，在具体的子项目引入真正的依赖
去掉以下部分

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

完整的父工程pom.xml文件为

<?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><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.2.0</version><relativePath/> <!-- lookup parent from repository --></parent><packaging>pom</packaging><!--这一部分改为自己的--><groupId>com.zhenbang</groupId><artifactId>spring-cloud</artifactId><version>0.0.1-SNAPSHOT</version><name>spring-cloud</name><description>spring-cloud</description><properties><java.version>17</java.version><maven.compiler.source>17</maven.compiler.source><maven.compiler.target>17</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><spring-cloud.version>2023.0.3</spring-cloud.version><spring-cloud-alibaba.version>2023.0.1.3</spring-cloud-alibaba.version></properties><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring-cloud-alibaba.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

最终是这样的，删除无关文件

3、在spring-cloud项目中新建一个services模块

   <parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.2.0</version><relativePath/> <!-- lookup parent from repository --></parent>

普通java就可以，不用选springboot,因为父工程已经已经是springboot项目了，子工程也是了，根本原因就是上面这段！！！

4、在services模块下的pom文件也要加上，因为它也不写具体代码

<packaging>pom</packaging>

可以删除services下的src

5 、在services模块下创建真正的具体微服务模块

在service-product这个具体微服务模块下的pom文件下引入真正的依赖包

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

6、修改service-product的微服务主函数

package com.zhenbang;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class ProductMainApplication {public static void main(String[] args) {SpringApplication.run(ProductMainApplication.class,args);}
}

7、配置yam文件

先在services pom文件下引入依赖

   <dependencies><!-- Nacos服务发现 --><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId></dependency></dependencies>

spring:application:name: service-productcloud:nacos:server-addr: 127.0.0.1:8848server:port: 9000

前提是安装Nacos,本地运行起来!!!
