微服务架构

user-server示例

1.导入依赖

 <!--客户端-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <!--web-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

2.主配置类注解开启@EnableEurekaClient
可以不加注解–默认开启

@SpringBootApplication
@EnableEurekaClient
public class UserApplicationConfig {

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

}

3.application.yml

eureka:
  client:
    serviceUrl:
      defaultZone: http://peer1:1000/eureka/,http://peer2:1001/eureka/ #连接服务器端
  instance:
    instance-id: user-server:3000 #当前客户端服务的id
    prefer-ip-address: true # 使用ip进行注册
server:
  port: 3000 #端口号

spring:
  application:
    name: user-server  #当前应用名称
