基於SpringCloud Eureka 搭建服務注冊中心

新建一個springboot項目:eureka-server

添加Maven依賴信息 :

 <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> <!-- 注冊中心核心依賴 -->  <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必須實現高可用至少2個 2個eureka是互相注冊 3個eureka則是兩兩互相注冊
      #defaultzone: http://127.0.0.1:8761/eureka/ 即1注冊到2 2注冊到1
      #defaultzone: http://127.0.0.1:8761/eureka/,http://127.0.0.1:8762/eureka/
      #即 啟動1時 將1注冊到2和3 啟動2時 將2注冊到1和3  啟動3時 將3注冊到1和2
    register-with-eureka: false #本身就是一個注冊中心所以不需要自己注冊進eureka
  server:
    enable-self-preservation: false #eureka server 的自我保護 開發環境關閉 生產環境打開

在啟動類中進行配置@EnableEurekaServer配置

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