微服务的使用(一)

微服务的创建（一）

1 创建父工程项目 cloud-demo

项目结构

2 创建nacos-server和eureka-server 服务 ,创建方式和上面一样

3 编写父工程的pom文件

<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">

此时的项目结构

编写nacos-server项目中的pom.xml文件

<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>4.0.0modelVersion>
   
    <parent>
        <groupId>org.examplegroupId>
        <artifactId>cloud-demoartifactId>
        <version>1.0-SNAPSHOTversion>
    parent>

    <artifactId>nacos-serverartifactId>
    <packaging>jarpackaging>

    <name>nacos-servername>
    <url>http://maven.apache.orgurl>

    <properties>
        <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
        <junit.version>4.13.2junit.version>

    properties>

    <dependencies>
        <dependency>
            <groupId>junitgroupId>
            <artifactId>junitartifactId>
            <version>${junit.version}version>
            <scope>testscope>
        dependency>
        <dependency>
            <groupId>com.alibaba.cloudgroupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discoveryartifactId>
        dependency>
        <dependency>
            <groupId>org.projectlombokgroupId>
            <artifactId>lombokartifactId>
        dependency>
    dependencies>
project>

此时我们能看到文件中出现的蓝色向上箭头，代表已经继承了父工程中的依赖容器。
