【维普】软件工程-基于SpringBoot的“新能源汽车”

目录I7结束语通过毕业设计的软件开发过程，我深刻认识到利用SpringBoot框架可以快速、可靠地开发出一个高效率、高性能的平台。该平台可以通过使用SpringBoot中的自动配置来简化开发工作，并可以通过模块化的方式进行构建，便于日后维护和扩展。其次，在平台的实现上采用了前后端分离的设计思想，后端采用SpringBoot框架，前端采用Vue.js框架。通过使用前后端分离的设计思想，实现了系统的系统的高并发、响应快、低耦合、易维护等目标。通过本次研究，我深刻认识到，新能源汽车产业的快速发展为新能源汽车资讯平台的应用提供了广阔的市场和前景。同时，我也意识到，在平台的设计和实现过程中，要注重用户体验和交流互动，建立可信赖的服务和机制。未来，该平台有很大的应用前景，希望可以进一步扩大应用范围，推动新能源汽车工业的发展。参考文献参考文献[1]周欢.新能源汽车节能技术的应用[J].时代汽车,2021(01).[2]赵剑,刘增刚.汽车资讯信息平台系统的设计与实现[J].长春大学报,2017,27（08):30-34.[3]李雪源.浅论软件需求分析[J].信息与电脑(理论版).
