?

啟動類代碼如下：

package com.atguigu.springcloud;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.netflix.eureka.EnableEurekaClient;@SpringBootApplication @EnableEurekaClient //本服務啟動后會自動注冊進eureka服務中 //@EnableDiscoveryClient //服務發現 public class DeptProvider8001_App {public static void main(String[] args) {SpringApplication.run(DeptProvider8001_App.class, args);} }

?

application.yml文件

注意：數據庫clouddb01 的創建

DROP DATABASE IF EXISTS clouddb01 ; CREATE DATABASE clouddb01 CHARACTER SET UTF8; USE clouddb01; CREATE TABLE dept (deptno BIGINT NOT NULL PRIMARY KEY AUTO_INCREMENT ,dname VARCHAR(60),db_source VARCHAR(60) );INSERT INTO dept(dname,db_source) VALUES('開發部',DATABASE()); INSERT INTO dept(dname,db_source) VALUES('人事部',DATABASE()); INSERT INTO dept(dname,db_source) VALUES('財務部',DATABASE()); INSERT INTO dept(dname,db_source) VALUES('市場部',DATABASE()); INSERT INTO dept(dname,db_source) VALUES('運維部',DATABASE());SELECT * FROM dept;

1，啟動eureka-server-7001

2，啟動eureka-provider-8001

3，http://localhost:7001/

有上圖所示可以知道我們已經將服務提供者注冊到注冊中心

關于上圖簡單介紹：

application：MICROSERVICECLOUD-DEPT? ? 這個就是被注冊進來的服務名稱在application.yml文件中配置

spring:
? ?application:
? ? name: microservicecloud-dept?

status：microservicecloud-dept8001? ? ? ? ? ? ? ? ? 這個如下入application.yml文件位置的配置

?

服務的提供者已經實現
