【ERP项目开发】001.ERP简介、工程搭建

ERP项目开发系列笔记，是我所做的大学毕业设计的项目，基于真实企业的模拟开发。本系列对应录播视频可从哔哩哔哩观看。

001.ERP简介、工程搭建——哔哩哔哩链接：http://www.bilibili.com/video/av31046112

1. ERP是什么

Enterprise Resource Planning，企业资源计划

企业资源计划是指建立在信息技术基础上，以系统化的管理思想，为企业决策层及员工提供决策运行手段的管理平台。

ERP的功能模块

• 供应链（物流）
• 销售（商贸）【本项目所属类型】
• 财务（all）
• 生产（制造业）

2. 本项目做的ERP简介

这是一个进销存ERP，为商贸公司所做。

进销存：采购、销售、仓储。

它对应的四套主线业务：采购、销售、采购退货、销售退货。

3. 本项目的概览

3.1 登录之后的主页

3.2 基础维护

比较常见的部门-员工-角色-资源的基于权限模型的基础数据的维护。

3.3 商品

1-M-N的一对多→一对多（三级联动）

3.4 采购、销售业务【进、销】

包含了采购、销售两套主线业务。

3.5 仓库【存】

3.6 报表中心

老板、财务不管你的订单业务，他们只关心：钱

4. 以采购业务为例，介绍主线业务流程

4.1 新建采购订单

4.2下单完成后可查看详情

4.3 采购订单新建完毕后，需要采购主管审核

4.4 如果订单不合适/不可行，可驳回订单

之后会弹出一个对话框：是否允许订单修改。

4.5 驳回后选择修改，此时不能再审核，订单状态变为“等待修改”

4.6 修改订单后重新审核通过

此时审核列表页中不再显示该订单

4.7 订单出现在了运输任务指派页

4.8 运输任务指派

4.9 指派完成后，该订单只会出现在指定跟单人的列表页中

4.10 订单启动

需要注意两个问题：供应商是否送货；如果不送货是否使用物流(如果不送货、不使用物流，则只能自己去拉货)

4.11 选择：不送货、使用物流

此时订单状态变为“选择物流公司”

4.12 点击“详细”

单选按钮变成了状态值，且多了填写运单号的按钮

4.13 选择物流公司、并填写运单号

4.14 填写完成后，状态变为“入库”

4.15 点击详细→入库，加载入库单

动态ajax入库，当最后一个订单项入库完成后，订单要结束。

5. 工程架构和技术选型

工程结构比较普通、经典的架构模式分层、分模块开发

技术选型主要以SSM为主

• Spring（包括MVC）——贯穿整个项目
• Dubbo+Zookeeper——工程之间的服务调用（ERP主模块可以调用运输模块的服务，也可以调用客户管理模块的服务）
• MyBatis——持久层框架
• MySQL+Druid——数据库连接
• Activiti——工作流框架（本ERP项目是基于流程的业务系统）
• poi——报表导出
• Shiro——安全框架，用于权限校验
• jsp，servlet

6. 开发环境

STS3.9.5+MySQL5.5+jdk1.8

使用STS时注意的小技巧

把原来的.metadata文件夹整个的拷到另一个全新的工作目录下，可以实现配置的拷贝。

7. 工程搭建

用Maven搭建工程

7.1 erp-parent工程

跳过骨架，注意打包方式

7.2 erp-manager工程搭建

也是需要搭建聚合工程，注意继承parent（继承parent，之后所有的工程都可以由parent管理jar的版本）

7.9 运行erp-manager，Run as Maven build…（clean tomcat7:run）

出现以下错误：

很明显：erp-parent未安装到本地仓库。

7.10 将erp-parent安装到本地仓库后，重新运行

7.11 再运行Maven install（clean tomcat7:run）

8. 创建数据库

8.1 登录MySQL

8.2 创建：create database erp2（注意有分号！）

8.3 考虑到安全问题，不能直接用root，需要创建新的数据库用户实体

8.4 给erp_user授权

8.5 用erp_user重新登录数据库

8.6 再次重新启动erp工程

（注意：第一次成功后，Activiti会自动创建表 ）

至此，工程框架结构已搭建完成。

（完）
