1、项目介绍及开发技术

1.1 项目介绍

随着网络的飞速发展，网络技术的应用越来越广泛，而信息技术的飞速发展，计算机管理系统的优势也逐渐体现出来，大量的计算机电子信息已经进入千家万户。物品租赁系统已跟随信息时代的重要代表，由于涉及的数据量大，以往人工管理已难以维护，因此采用信息技术进行管理。计算机系统管理模式代替了人工管理的方式，比以往人工管理的方式，采用计算机使物品租赁系统查询方便，信息准确性高，降低成本，提高效率，本系统的开发主要以物品租赁为对象，根据功能需求开发信息系统。

该系统基于Hadoop平台，利用Java语言、MySQL数据库，结合目前流行的 B/S架构，将物品租赁管理的各个方面都集中到数据库中，以便于用户的需要。在确保系统稳定的前提下，能够实现多功能模块的设计和应用。

1.2 开发技术

Java开发语言、SpringBoot、Hadoop、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS、Scrapy。

3、功能截图

3.1 前台功能

当人们打开系统的网址后，首先看到的就是首页界面。在这里，人们能够看到物品租赁系统的导航条，通过导航条进入各功能信息展示页面进行操作。

用户注册：在用户注册页面输入用户注册信息进行注册操作。

物品信息：在物品信息页面的输入栏中输入物品名称和选择物品类别进行查询，可以查看到物品详细信息，并进行租赁、评论或收藏操作。

物品出租：在物品出租页面的输入栏中输入标题、类别和联系人进行查询，可以查看到物品出租详情，并进行收藏操作。

后台管理：用户注册登录系统后，在首页页面点击后台管理可以对个人中心、物品租赁管理、物品归还管理、评价信息管理、我的收藏管理等进行详细操作。

3.2 后台功能

管理员登录，在登录页面正确输入用户名和密码后，点击登录进入操作系统进行操作。

管理员进入主页面，主要功能包括对个人中心、用户管理、公告类型管理、公告信息管理、物品类别管理、物品信息管理、物品租赁管理、物品归还管理、评价信息管理、物品出租管理、系统管理等进行操作。 

管理员点击用户管理。进入用户页面输入用户账号可以查询，新增或删除用户列表，并根据需要对用户详细信息进行查看详情，修改或删除操作。

管理员点击公告信息管理。进入公告信息页面输入标题、简介和发布人可以查询，新增或删除公告信息列表，并根据需要对公告详细信息进行查看详情，修改或删除操作。

管理员点击物品信息管理。进入物品信息页面输入物品名称和选择物品类别可以查询或删除物品信息列表，并根据需要对物品详细信息进行查看详情、修改、查看评论或删除操作。

管理员点击评价信息管理。进入评价信息页面输入物品名称和物品类别可以查询或删除评价信息列表，并根据需要对评价详细信息进行查看详情、修改或删除操作。

管理员点击物品出租管理。进入物品出租页面输入标题、类别和联系人可以查询、爬取数据、新增或删除物品出租列表，并根据需要对物品出租详细信息进行修改或删除操作。

管理员进行爬取数据后，点击主页面右上角的看板，可以查看到系统简介、用户总数、物品信息总数、物品租赁总数、物品出租总数、类别统计、联系人统计、商家地址统计、发贴统计、租赁数量统计、出租量统计、物品出租等实时的分析图进行可视化管理。

管理员点击系统管理，进入系统管理页面可以对轮播图管理、关于我们和系统简介进行详情或修改操作，在闲置资讯页面输入标题可以查询，新增或删除闲置资讯列表，并根据需要对闲置资讯详细信息进行查看详情，修改或删除操作。

4、数据库表结构设计
