下载nacos
因为在我们的项目中所有的微服务都依赖的common工程，所以就把common工程作为注册发现工程
1.pom文件中导入依赖

启动nacos 用户名和密码都是nacos
localhost:8848/nacos
以gulimail-coupon项目为例子
1.导入依赖
<?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>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.8.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.lcl.gulimail</groupId>
<artifactId>gulimail-coupon</artifactId>
<version>1.0-SNAPSHOT</version>
<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Greenwich.SR3</spring-cloud.version>
</properties>
<dependencies>
<dependency>
<groupId>com.lcl.gulimail</groupId>
<artifactId>gulimail-common</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<!-- mysql驱动 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
<!-- nacos的注册依赖 -->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
<version>2.1.0.RELEASE</version>
</dependency>
<dependency>

</dependencies>
<dependencyManagement>
<dependencies>

<version>${spring-cloud.version}</version>

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

</plugins>
</build>
</project>
2.修改application.yml文件
spring:
datasource:
username: root
password: root
url: jdbc:mysql://localhost:3306/gulimall_sms
driver-class-name: com.mysql.jdbc.Driver
application:
name: gulimail-coupon
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
mybatis-plus:
mapper-locations: classpath:/mapper/**/*.xml
global-config:
db-config:
id-type: auto
server:
port: 7000
3.在启动类中加入自动开启注册功能
package com.lcl.gulimail.coupon;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@EnableDiscoveryClient
@SpringBootApplication
public class GuliMailCouponApplication {
public static void main(String[] args) {
SpringApplication.run(GuliMailCouponApplication.class,args);
}
}
