初涉Eureka

1.注册中心的搭建

1. pom文件中引入相关的包

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-netflix-eureka-server</artifactId>
    <version>1.4.0.RELEASE</version>
</dependency>

2. 配置文件的编写

server:
  port: 1066
spring:
  application:
    name: cloud-eureka-server
eureka:
  client:
    fetch-registry: false
    register-with-eureka: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  instance:
    hostname: 127.0.0.1
  server:  
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 5000

3.启动类加@EnableEurekaServer注解

@EnableEurekaServer
@SpringBootApplication
public class CloudEurekaServerApplication {

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

}

2.服务提供者的搭建

1. pom文件中引入相关的包

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-netflix-eureka-server</artifactId>
    <version>1.4.0.RELEASE</version>
</dependency>

2. 配置文件的编写

server:
  port: 8094

spring:
  application:
    name: eurekaClient
eureka:
  client:
    serviceUrl:
      defaultZone:  http://127.0.0.1:1066/eureka/
    eureka-server-read-timeout-seconds: 180

3.启动类加@EnableEurekaClient 注解

@EnableEurekaClient
@SpringBootApplication
public class CloudService1Application {

    public static void main(String[] args) {
        SpringApplication.run(CloudService1Application.class, args);
    }

}


简单的Eureka就这么搭建完了，消费者的搭建与服务提供者类似，这里就不详细写了。需要注意的是Spring Boot2.0以上，不支持1.4版本的Eureka，若没注意，消费者的使用中会出现各种问题。
