5-Eureka快速入门

搭建注册中心

项目结构：

添加服务端

导包

配置

 
server:  
  port: 8761 #eureka 默认端口  
  
spring:  
  application:  
    name: eureka-server-01
 

Java

@SpringBootApplication  
@EnableEurekaServer // 开启eureka注册中心功能  
public class EurekaServer01Application {  
  
    public static void main(String[] args) {  
        SpringApplication.run(EurekaServer01Application.class, args);  
    }  
  
}

运行

运行主程序

浏览器查看

浏览器打开 8761 端口，可以查看eureka面板

添加客户端

代码

需要eureka客户端依赖

<dependency>  
    <groupId>org.springframework.cloud</groupId>  
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>  
</dependency>

在启动类中添加client注解

@SpringBootApplication  
@EnableEurekaClient //eureka 客户端  
public class EurekaClientBApplication {  
  
    public static void main(String[] args) {  
        SpringApplication.run(EurekaClientBApplication.class, args);  
    }  
  
}

运行

可以添加多个客户端，只要保证不会端口冲突就行 ok，咱们的客户端和服务端都跑成功了
