2、SpringCloud 第一课 Eureka 注册中心

1、pom.xml 中添加依赖 eureka-server

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2、application.properties

spring.application.name=one-eurekas-erver

#默认设置下，这个服务注册中心会将自己作为客户端，所以需要禁用它的客户端注册行为 下面5个
# 服务注册中心 端口
server.port=1111
#主机
eureka.instance.hostname=localhost
#这个为注册中心，false代表不向注册中心注册自己 ##直接启动之后会发现这个是空的，说明注册中心没有注册任何服务
eureka.client.register-with-eureka=false
#注册中心的职责就是维护服务实例，并不需要它去检索服务，所以将它关闭
eureka.client.fetch-registry=false
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

# 关闭保护机制
#eureka.server.enable-self-preservation=false

logging.file=${spring.application.name}.log

3、spring boot启动类

@EnableEurekaServer  //开启Eureka服务注册中心的支持,用来供给其他营业进行对话
@SpringBootApplication
public class OneEurekasErverApplication {

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

4、测试

5、源码下载
