Eureka 笔记

服务端：

创建springBoot 项目

1.步骤 导入在pom.xml中         导入        eureka-server的 jar包

2.步骤 在主方法加注解        @EnableEurekaServer

3. 步骤 在配置config

1.步骤pox.xml:

2.步骤 :加注解@EnableEurekaServer

package com.csdn;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
 
 
@SpringBootApplication
@EnableEurekaServer //2步骤 加注解@EnableEurekaServer
public class MainApplication {
 
	public static void main(String[] args) {
		SpringApplication.run(MainApplication .class, args);
	}
 
}

3. 步骤 : resources/application.properties 进行配置

# 3. 步骤config 配置
#eureka服务端应用的端口默认是8761
server.port=9000
#表示是否将自己注册到Eureka Server,默认为true,由于当前应用就是Eureka Server,故而设为false
eureka.client.register-with-eureka=false
# 表示是否从Eureka Server获取注册信息,默认为true,因为这是一个单点的Eureka Server,不需要同步其他的Eureka Server节点的数据,故而设为false
eureka.client.fetch-registry=false
#暴露给其他eureka client客户端 的注册地址
eureka.client.service-url.defaultZone: http://localhost:9000/eureka/

客户端：

1.步骤 导入在pom.xml中         导入        eureka-client的 jar包

 
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-clientartifactId>
        dependency>

2. 步骤 : resources/application.properties 进行配置

# 3. 步骤config 配置
server.port=8001
#注册到eureka服务端的微服务名称
spring.application.name=ms-consumer-user
#注册到eureka服务端的地址
eureka.client.service-url.defaultZone=http://localhost:9000/eureka/
#点击具体的微服务，右下角是否显示ip
eureka.instance.prefer-ip-address=true
#显示微服务的名称
eureka.instance.instance-id=ms-consumer-user-8001

URL访问地址：http://localhost:9000/
