文末获取源码

功能介绍

该项目未使用spring框架，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、交易管理的CRUD，使用Proxy实现Service层的动态代理，实现DAO层事务控制，有助于深入理解web项目。管理员还包含系统设置：用户管理、角色管理、权限管理；其中角色管理可以设置总经理、副总经理、销售经理、综合事务等角色的权限菜单。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。

2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
5.是否Maven项目: 否；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目 
6.数据库：MySql 5.7版本；

技术栈

1. 后端：Servlet+Mybatis

2. 前端：Layui+jquery+echarts+JSP

使用说明

1. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;

若为maven项目，导入成功后请执行maven clean;maven install命令，下载所需jar包；

2. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
3. 将项目中db.properties配置文件中的数据库配置改为自己的配置
4. 配置tomcat，然后运行项目，输入localhost:8080/xxx 登录
5. 管理员账户:admin  密码:123456
普通员工账户：zs  密码：123
