二、新建spring cloud alibaba项目并注册服务到nacos

1. 新建spring cloud alibaba项目

1.1 新建maven项目

1.1.1 创建项目

新建chariot-micro项目，语言选择java，构建工具选择maven，jdk使用本地的22.0.2，java级别选择21，打包方式为Jar。如下图所示：

1.1.2 选择spring boot版本

选择spring boot版本为3.5.6，依赖全部不选择。

点击【Create】按钮，生成项目，整理项目文件如下图所示：

1.1.3 父项目文件整理

• 主项目pom文件内容如下：

<?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">

	</dependencyManagement>

	<dependencies>

	</dependencies>

</project>

删除src文件，新建订单模块(chariot-micro-order)、新建支付模块(chariot-micro-pay)

1.1.4 新建订单模块chariot-micro-order)并注册服务到nacos

pom文件内容如下：

<?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>
    <parent>
        <groupId>com.myp</groupId>
        <artifactId>chariot-micro</artifactId>
        <version>0.0.1</version>
    </parent>

    <artifactId>chariot-micro-order</artifactId>

    <properties>
        <maven.compiler.source>22</maven.compiler.source>
        <maven.compiler.target>22</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>

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

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

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

application.yml内容如下：

server:
  port: 8071

spring:
  application:
    name: order-service
  cloud:
    # 注册服务到nacos
    nacos:
      discovery:
        group: ORDER_GROUP
        server-addr: 127.0.0.1:8848

1.1.5 新建支付模块(chariot-micro-pay)并注册服务到nacos

pom文件内容如下：

<?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"

    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.myp</groupId>
        <artifactId>chariot-micro</artifactId>
        <version>0.0.1</version>
    </parent>

    <artifactId>chariot-micro-pay</artifactId>

    <properties>
        <maven.compiler.source>22</maven.compiler.source>
        <maven.compiler.target>22</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>

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

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

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

application.yml内容如下：

server:
  port: 8091

spring:
  application:
    name: pay-service
  cloud:
    # 注册服务到nacos
    nacos:
      discovery:
        group: PAY_GROUP
        server-addr: 127.0.0.1:8848

2. 验证服务注册到nacos是否成功

2.1 启动订单服务(chariot-micro-order)和支付服务(chariot-micro-pay)

2.2 启动nacos

打开cmd窗口，cd到nacos下的bin文件夹，执行启动nacos命令 .\startup.cmd -m standalone。

2.3 在nacos管理界面查看服务

在nacos管理界面中出现了order-service服务和pay-service
