【Spring Cloud】服务注册与发现Eureka

一、环境准备

• JDK Version: 1.8

• Maven Version: 3.6.2

• IDEA工具

  安装以上东东，并配置环境变量

二、创建服务注册发现中心

新建spring boot项目

spring boot version: 2.3.4.RELEASE

创建步骤略

spring cloud version

Hoxton.SR8

添加依赖

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

服务配置

• application.yml

  server:
    port: 8000 //服务接口
  spring:
    application:
      name: eureka-server //服务名称
  eureka:
    instance:
      hostname: localhost
    client: //是否将自身也注册为一个服务
      register-with-eureka: false
      fetch-registry: false
  
  

• 添加注解@EnableEurekaServer

  @EnableEurekaServer
  @SpringBootApplication
  public class EurekaServerApplication {
  
      public static void main(String[] args) {
          SpringApplication.run(EurekaServerApplication.class, args);
      }
  
  }
  

三、运行结果

• 输入http://localhost:8000
