前后端交互概念

1前后端分离开发概念
2搭建后端环境
gitee使用

1前后端分离开发概念

前段：运用html、css、js和现成库，对数据作展示。
后端：运用Java和Java框架，提供数据或操作。
前段通过ajax 调用后端，后端通过json 提供数据和逻辑操作。
后端的开发接口：controller、service、mapper
在这里插入图片描述

2搭建后端环境

在这里插入图片描述
项目模块构建
hospital-manage：医院接口模拟端（已开发，直接使用）
yygh-parent：根目录，管理子模块：
-common：公共模块父节点
-common-util：工具类模块，所有模块都可以依赖于它
rabbit-util：rabbitmq业务封装
-service-util：service服务的工具包，包含service服务的公共配置类，所有 service模块依赖于它
server-gateway：服务网关
-model：实体类模块
-service：api接口服务父节点
service-hosp：医院api接口服务
service-cmn：公共api接口服务
service-user：用户api接口服务
service-order：订单api接口服务
service-oss：文件api接口服务
service-sms：短信 api接口服务
service-task：定时任务服务
service-statistics：统计api接口服务
service-client：feign服务调用父节点
service-cmn-client：公共api接口
service-hosp-client：医院api接口
service-order-client：订单api接口
service-user：用户api接口
