springcloud的学习---euerka集群的使用

在开始之前先跟大家说一下，这里我改了映射，所以先到C:\Windows\System32\drivers\etc文件夹下 修改

集群的使用： 步骤： 1创建一个集群module

2在pom里面加入注册中心服务端依赖

<?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>springcloud</artifactId> <groupId>com.zsp</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>cloud-eureka-server7002</artifactId> <dependencies> <dependency> <groupId>com.zsp</groupId> <artifactId>cloud-api-commons</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <!--eureka-server--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <!--自定义api通用包--> <!--<dependency> <groupId>org.xzq.springcloud</groupId> <artifactId>cloud-api-commons</artifactId> <version>${project.version}</version> </dependency>--> <!--boot web acctuator--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <!-- 热部署工具--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency> </dependencies> </project>

3配置yml文件

server: port: 7002 eureka: instance: hostname: eureka7002.com #eureka服务端实例名称 client: register-with-eureka: false #表面不注册进注册中心 fetch-registry: false #表明自己是注册中心节点 service-url: defaultZone: http://eureka7001:7001/eureka/

4写主启动类

package com.zsp; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer; @SpringBootApplication @EnableEurekaServer public class EurekaMain7002 { public static void main(String[] args) { SpringApplication.run(EurekaMain7002.class,args); } }

当然，先前已经是服务中心的就不用这么复杂 改一下application.yml即可

server: port: 7001 eureka: instance: hostname: eureka7001.com client: register-with-eureka: false #false表面不注册自己 fetch-registry: false #false表明自己是注册中心 service-url: defaultZone: http://eureka7002:7002/eureka/

最后效果
