SpringCloud - 2. 服务注册 和 发现

SpringCloud 的服务注册和发现是由Eureka来完成。

1.eureka server

1.1 依赖

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

1.2 @EnableEurekaServer 注册服务

@SpringBootApplication
@EnableEurekaServer //开启服务注册中心
public class EurekaServerApplication
{

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

1.3. 配置

server:
  port: 8761
eureka:
  instance:
    hostname: localhost
  client:
    # 表示本应用是否是向注册中心注册自己
    register-with-eureka: false
    # 是否检索服务
    fetch-registry: false

2. eureka client

2.1 依赖

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

2.2  @EnableDiscoveryClient

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

2.3 配置

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/  # 客户端名称
  instance:
    hostname: client-1
spring:
  application:    # 注册到服务端名称
    name: eureka-client# 客户端端口
server:
  port: 8081
