基于SpringCloud Eureka 搭建服务注册中心

新建一个springboot项目:eureka-server

添加Maven依赖信息 :

 <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>xxxx.com.cn</groupId> <artifactId>eureka</artifactId> <version>0.0.1-SNAPSHOT</version> <name>eureka</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> <spring-cloud.version>Finchley.SR2</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- 注册中心核心依赖 -->  <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>

application.yml配置:

spring:
  application:
    name: eureka
server:
  port: 8761
eureka:
  client:
    service-url:
      defaultzone: http://127.0.0.1:8762/eureka/
      #eureka必须实现高可用至少2个 2个eureka是互相注册 3个eureka则是两两互相注册
      #defaultzone: http://127.0.0.1:8761/eureka/ 即1注册到2 2注册到1
      #defaultzone: http://127.0.0.1:8761/eureka/,http://127.0.0.1:8762/eureka/
      #即 启动1时 将1注册到2和3 启动2时 将2注册到1和3  启动3时 将3注册到1和2
    register-with-eureka: false #本身就是一个注册中心所以不需要自己注册进eureka
  server:
    enable-self-preservation: false #eureka server 的自我保护 开发环境关闭 生产环境打开

在启动类中进行配置@EnableEurekaServer配置

@SpringBootApplication @EnableEurekaServer //开启eurekaServer public class EurekaApplication { public static void main(String[] args) { SpringApplication.run(EurekaApplication.class, args); } }
