SpringBoot实现Eureka注册功能

一、新建两个子模块，我这边的命名Eureka和Client，在父级的pom.xml

<!-- 集成web方式的开发 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- 服务与注册中心 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>

二、在Eureka中新建package、Application服务需要在包下才能正常加载启动，根目录下启动会报异常

package eureka;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer --作为服务端注解
public class EurekaServer {

public static void main(String[] args) {
new SpringApplicationBuilder(EurekaServer.class).web(true).run(args);
}
}

Eureka下的application.yml

server:
port: 9001
eureka:
instance:
hostname: localhost
prefer-ip-address: true
client:
register-with-eureka: false #不作为服务注册
fetch-registry: false #单点服务不需要同步其他服务数据
service-url:
defaultZone: http://localhost:9001/eureka/ #服务注册地址

三、Client下新建package和Application

package redis;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient --作为客户端注解
public class RedisServer {

public static void main(String[] args) {
new SpringApplicationBuilder(RedisServer.class).web(true).run(args);
}
}

Client下application.yml

server:
port: 9009
spring:
application:
name: springCloud-redis
eureka:
instance:
hostname: localhost
client:
register-with-eureka: true
fetch-registry: false
service-url:
defaultZone: http://localhost:9001/eureka/[/code] 四、启动Eureka、Client,浏览器访问http://localhost:9001
