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);
    }
}
