下载nacos
https://github.com/alibaba/nacos/releases
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
<?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"> <parent> <artifactId>gulimail</artifactId> <groupId>com.lcl.gulimail</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>gulimail-common</artifactId> <description>这个项目是一个公共模块，每个微服务的bean 工具类</description> <dependencies> <!-- 这个项目是用mybatisPlus开发的 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.2.0</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore --> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpcore</artifactId> <version>4.4.12</version> </dependency> <!-- 工具类 --> <dependency> <groupId>commons-lang</groupId> <artifactId>commons-lang</artifactId> <version>2.6</version> </dependency> <!-- mysql驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.6</version> </dependency> <!-- servlet --> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.1.0.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> </project>
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>

</dependency>

<plugins>
<plugin>

</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);
}
}
