    项目介绍

    本项目分为前后台，主要分为管理员与用户两种角色，管理员登录后台，普通用户登录前台；
    管理员角色包含以下功能：
    管理员登录,订单管理,客户管理,水果管理,商品类目管理等功能。

    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.数据库：MySql 5.7版本；

    6.是否Maven项目：否；

    技术栈

    1. 后端：Servlet

    2. 前端：JSP+CSS+JavaScript+jQuery+Bootstrap

    使用说明

    1. 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；
    2. 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，然后运行；
    3. 将项目中src/utils/DBUtil.java配置文件中的数据库配置改为自己的配置;
    4. 运行项目，输入localhost:8080/jsp_shuiguosaleshop 登录 注：Tomcat中配置路径必须为jsp_shuiguosaleshop，否则会出问题；
    用户账号/密码： user/123456

    管理员账号/密码：admin/admin
