摘 要

随着信息化时代的到来,管理系统都趋向于智能化、系统化,基于vue的木里风景文化管理平台也不例外,但目前国内的市场仍都使用人工管理,市场规模越来越大,同时信息量也越来越庞大,人工管理显然已无法应对时代的变化,而木里风景文化管理平台能很好地解决这一问题,轻松应对木里风景文化平时的工作,既能提高人力物力财力,又能加快工作的效率,取代人工管理是必然趋势。

基于vue的木里风景文化管理平台以ssm作为框架,b/s模式以及MySql作为后台运行的数据库,同时使用Tomcat用为系统的服务器。本系统主要包括以下功能模块:首页,个人中心,用户管理,旅游公告管理,景区管理,景区商品管理,门票管理,景区美食管理,旅游交通工具管理,红黑榜管理,我的收藏管理,系统管理等模块,通过这些模块的实现能够基本满足日常木里风景文化管理的操作。

本文着重阐述了木里风景文化管理平台的分析、设计与实现,首先介绍开发系统和环境配置、数据库的设计,接着说明功能模块的详细实现,最后进行了总结。

关键词:木里风景文化管理平台; ssm;MySql数据库;Tomcat;

Abstract

With the advent of the information age, the management system tends to be intelligent and systematic, based on the VUE Muli landscape culture management platform is no exception, but the current domestic market is still using manual management, the market size is getting larger and larger, while the amount of information is also more and more huge, manual management has obviously been unable to cope with the changes of the times, and the Muli landscape culture management platform can solve this problem very well, easily cope with the usual work of Muli landscape culture, both to improve human and material resources, but also to accelerate the efficiency of work, Replacing manual management is an inevitable trend.

The Wooden Landscape Culture Management Platform based on VUE uses ssm as the framework, b/s mode and MySql as the database running in the background, and Tomcat as the system's server. The system mainly includes the following functional modules: homepage, personal center, user management, tourism announcement management, scenic spot management, scenic commodity management, ticket management, scenic food management, tourist vehicle management, red and black list management, my collection management, system management and other modules, through the realization of these modules can basically meet the daily Muli landscape culture management operation.

This paper focuses on the analysis, design and implementation of the Muli landscape culture management platform, first introduces the development system and environmental configuration, database design, then explains the detailed implementation of the functional module, and finally summarizes.

Key words: Muli landscape culture management platform; ssm; MySql database; Tomcat;
