Spring Cloud服务注册【Eureka】

创建Eureka项目

结构如下图所示

需要修改的地方

启动控制台页面显示

浏览器访问http://localhost:8761

微服务项目整合Eureka

启动类启用Eureka

@SpringBootApplication(scanBasePackages = {"com.example.demo"})
@MapperScan("com.example.demo.*") //扫描的mapper
@EnableEurekaClient
public class DemoApplication {

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

}

pom文件引入Eureka配置信息

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:8761/eureka/

pom添加相关依赖
