文末获取源码

- 本应用是一个客户关系管理系统，主要包括五大模块，分别是营销管理，客户管理，服务管理，统计报表和系统管理，为客户关系管理提供简单的数据管理与分析

- 技术选型方面，该项目是一个`SpringBoot`的单体应用，项目使用`SpringBoot2`框架快速开发，数据访问层使用`Mybatis`框架，页面渲染引擎使用`Freemarker`，页面样式使用`Layui`，日志方面选用的是`logback`，统计报表部分使用的是`ECharts`,数据库使用的Mysql 8.0版本；

1.  在mysql(默认为mysql8)中创建名为`crm`的数据库，并执行源码根目录的`crm.sql`脚本生成数据库表以及数据
2.  将项目源码导入idea中，指定项目的jdk版本为jdk8或以上，并标记为maven项目，下载所需依赖
3.  修改`application.yml`中针对于数据库的配置(主要是数据库名和数据库密码)
4.  修改logback.xml中，第4行，日志文件的存储地址，改为自己的路径；

5.  启动项目测试是否正常，默认启动地址首页为`http://localhost:1212/crm`，默认数据库中的管理员为`admin`，密码为`123456`，可在登录系统之后自行修改用户密码
