Eureka搭建注册中心-简版

1.pom.xml依赖添加

<!-- Spring Boot -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <modelVersion>4.0.0</modelVersion>

    <artifactId>eureka-server</artifactId>


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

    <!-- Spring Cloud -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.SR2</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    

2.配置文件

spring:
  application:
    name: eureka-server

server:
  port: 8761
  
eureka:
  client:
    fetch-registry: false #由于注册中心的职责就是维护服务实例，它并不需要去检索服务，所以也设置为false
    register-with-eureka: false #由于该应用为注册中心，所以设置为false，代表不向注册中心注册自己

eureka.client.register-with-eureka一定要配置为false，不然启动时会把自己当作客户端向自己注册，会报错。

3.创建启动类

@SpringBootApplication
@EnableEurekaServer //表示开启Eureka Server
public class EurekaServerApplication {

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

}
