文末获取源码

项目编号：BS-XX-111

该项目主要基于JAVAWEB技术，开发了一套CRM客户关系管理系统，实现了用户登录，权限控制，数据统计，以及市场活动、线索、客户、联系人、合同的CRUD，使用Proxy实现Service层的动态代理，实现DAO层事务控制。

运行环境

jdk8+tomcat8+mysql5.7+IntelliJ IDEA

项目技术(必填)

java servlet+mybatis+layui+jquery+echarts

下面展示一下具体的功能界面：

系统主页面

市场活动管理：查询的相关数据可以导出到EXCEL表里

销售线索管理

客户管理

联系人管理

交易管理

个人信息管理

系统设置—用户管理

系统设置—角色管理

系统设置—权限管理
