使用SSM+Layui+Bootstrap实现汽车维保系统的示例代码

本项目主要实现对汽车维修厂的信息化管理功能，主要包含三个角色：管理员，维修师傅，客户。实现的主要功能包含用户管理、配置管理、汽车管理、故障管理、供应商管理、配件管理、维修订单管理、统计信息、公告管理、个人信息管理。主要业务流程：用户在系统内发起汽车维修申请定单，管理员根据情况将定单分配给维修师傅，维修师傅接受任务后开始维修，并根据情况申请配件，处理完成后由管理员生成最终支付订单结算费用，客户进入系统进行费用支付，并可以查看自己相应的维修记录和费用信息等等。

技术架构：

后台开发：SSM框架

前端技术：Layui+Jquery+Ajax

数据库：MYSQL

开发工具：IDEA /Eclipse

管理员登陆系统后的主要功能：

用户管理

配件管理

供应商管理

采购管理

车辆信息管理

故障管理

维修订单管理

统计管理

公告管理

库存管理

员工登陆系统

相应的管理模块

用户登陆系统

用户相关管理模块

以上是汽车维修管理系统的部分功能展示。
