Docker Compose部署微服務(wù)項(xiàng)目上線功能

更新時(shí)間：2022年07月05日 11:19:51 作者：Bug 終結(jié)者

這篇文章主要介紹了Docker Compose部署微服務(wù)項(xiàng)目上線,需求是這樣的編寫一個(gè)SpringBoot + Redis 的微服務(wù)項(xiàng)目，并提供 hello接口，每訪問一次接口，計(jì)數(shù)器+1，本文給大家分享實(shí)現(xiàn)思路，需要的朋友可以參考下

一、需求說明

編寫一個(gè)SpringBoot + Redis 的微服務(wù)項(xiàng)目，并提供 hello接口，每訪問一次接口，計(jì)數(shù)器+1

二、效果圖

在這里插入圖片描述

三、項(xiàng)目結(jié)構(gòu)

在這里插入圖片描述

目錄說明

docker-compose.yml ：項(xiàng)目的啟動(dòng)文件，配置編排等

Dockerfile：項(xiàng)目上線所需要的依賴，以及啟動(dòng)方式

四、核心源碼

??Java依賴與接口
