    1、项目介绍及开发技术

    1.1 项目介绍

    随着互联网技术的不断发展，人们的生活方式发生了巨大的变化。在这个信息化时代，人们越来越依赖于网络来获取信息、交流和解决问题。随着城市化进程的加快，越来越多的人涌入城市生活。然而，由于人口密度大、资源有限等原因，社区居民之间的物资交换需求逐渐增加。传统的线下交易方式效率低下，无法满足人们的需求。互联网技术的快速发展为社区物资交易提供了新的可能。通过互联网技术，人们可以实现信息的快速传递和共享，从而降低交易成本、提高交易效率。在这样的背景下，社区物资交易互助平台应运而生，为居民提供了一个便捷、高效的物资交换渠道。

    基于Spring Boot的社区物资交易互助平台是一个典型的Web应用程序，它采用了目前流行的微服务架构，具有良好的可扩展性和可维护性。该平台的主要功能包括用户注册与登录、发布物资需求或提供物资、浏览物资列表、在线沟通等。通过这个平台，居民可以方便地找到自己需要的物资，同时也可以将自己的闲置物品提供给需要的人，实现资源的合理利用和共享。

    本系统的设计现状和趋势涵盖了需求、结构、数据库等方面的设计，并实现了管理员和用户的特定功能。本文将从系统的设计、描述、实现、分析、测试等方面阐述开发过程。根据现实情况，本系统选择了可行的开发方案，并利用Java编程语言和MySQL数据库等技术实现了系统的全部功能。接下来，对系统进行了测试，以确保其无漏洞，并对用户权限进行了完善。最终，系统达到了相关标准。

    1.2 开发技术

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

    2、系统功能模块设计
