eureka 服务的注册与发现

一、项目结构

eureka-server为服务注册中心负责服务的管理

eureka-client 为eureka客户端

二、三步搭建eureka 服务注册中心

2.1 引入eureka服务端依赖

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

2.2 eureka 服务端配置

server:
  port: 8010
eureka:
  instance:
    hostname: localhost
  client:
    # 设置为false,代表不向注册中心注册自己
    register-with-eureka: false
    # 注册中心主要用于维护服务并不需要检索服务所以设置为false
    fetch-registry: false
    serviceUrl:
          defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

2.3 启动类上增加注解@EnableEurekaServer激活eureka服务端自动配置

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

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

}

三、三步搭建eureka 客户端

3.1 引入eureka客户端依赖

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

3.2 eureka 客户端配置

server:
  port: 8020
# 指定服务命名
spring:
  application:
    name: eureka-client
# 指定注册中心地址
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8010/eureka/

3.3 启动类上增加注解@EnableDiscoveryClient激活eureka客户端自动配置

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaClientApplication.class, args);
    }

}

4.启动项目

4.1 进入注册中心控制台,查看服务注册情况
