基于java的畅阅读系统小程序设计与实现
一、前言
畅阅读系统小程序，可以实现目标用户群需要的功能，首先对畅阅读微信小程序进行需求分析，得出畅阅读微信小程序主要功能。接着对畅阅读微信小程序进行总体设计和详细设计。总体设计主要包括小程序功能设计、小程序总体结构设计、小程序数据结构设计和小程序安全设计等；详细设计主要包括畅阅读微信小程序数据库访问的实现，主要功能模块的具体实现，模块实现关键代码等。最后对畅阅读微信小程序进行了功能测试，并对测试结果进行了分析总结，得出畅阅读微信小程序存在的不足及需要改进的地方，为以后的畅阅读微信小程序维护提供了方便，同时也为今后开发类似畅阅读微信小程序提供了借鉴和帮助。
二、系统功能设计
三、系统实现
畅阅读微信小程序登录界面，通过填写账号、密码、登录用户类型等信息进行登录，如图5-1所示。
图5-1登录界面图
用户注册，通过填写用户名、密码、姓名、性别、身份证、手机等信息，输入完成后选择提交即可注册成功，如图5-2所示。
图5-2用户注册界面图
用户登录进入首页，可以进行首页、书城、书架、我的等功能模块的查看与操作，如图5-3所示。
图5-3系统首页界面图
书城，在书城页面可以查看书籍名称、分类、字数、章节、封面、作者、价格、上架日期、是否完结、内容1、内容2、内容3等信息，进行购买，加入书架，如图5-4所示。
图5-4书城界面图
我的，在我的页面可以查看充值信息、扣费信息、书城、购买章节、章节信息、留言板等详细信息，如图5-5所示。
图5-5我的界面图
管理员通过填写用户名、密码、角色进行登录如图5-7所示。
图5-7管理员登录界面图
管理员通过填写用户名、密码、角色进行登录如图5-7所示。
