1、eureka服务端配置

1.1、配置父工程依赖

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <spring-cloud.version>Hoxton.SR10</spring-cloud.version>
    <mysql.version>5.1.47</mysql.version>
    <mybatis.version>2.1.1</mybatis.version>
</properties>

<dependencyManagement>
    <dependencies>
        <!-- springCloud -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <!-- mysql驱动 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>${mysql.version}</version>
        </dependency>
        <!--mybatis-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>${mybatis.version}</version>
        </dependency>
    </dependencies>
</dependencyManagement>
<dependencies>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
</dependencies>

1.2、新建maven项目

1.3、添加服务端依赖

<!--eureka服务端依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

1.4、添加启动类(EurekaApplication)

package com.wangzhan;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * @author wangzhan
 * @date 2022年07月11日 15:41
 */
@EnableEurekaServer // 开启eureka
@SpringBootApplication
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}

1.5、添加配置文件（application.yml）

server:
  port: 10086 # 服务端口
spring:
  application:
    name: eurekaserver  # eureka 服务名称
eureka:
  client:
    service-url:  # eureka的地址信息
      defaultZone: http://127.0.0.1:10086/eureka

2 eureka客户端配置

2.1、添加客户端依赖

<!--eureka客户端依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

2.2、修改配置文件

2.3、关于eureka客户端在启动类中加不加 @EnableEurekaClient 都能向注册中心注册的问题
