module:spring-cloud-eureka-server
1.1 添加Pom引用
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<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>
1.2 启动一个服务注册中心 只需要一个注解@EnableEurekaServer,这个注解需要在springboot工程的启动application类上加
@EnableEurekaServer
@SpringBootApplication
public class SpringCloudEurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringCloudEurekaServerApplication.class, args);
}
}
1.3 添加配置 eureka是一个高可用的组件,它没有后端缓存,每一个实例注册之后需要向注册中心发送心跳(因此可以在内存中完成),在默认情况下erureka server也是一个eureka client ,必须要指定一个 server。 eureka server的配置文件appication.yml:
server:
port: 7070
eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
service-url:
defaultZone: https://${eureka.instance.hostname}:${server.port}/eureka/
通过eureka.client.registerWithEureka:false和fetchRegistry:false来表明自己是一个eureka server.
