作者主页：[编程指南针] 作者简介：Java领域优质创作者、CSDN博客专家 、CSDN内容合伙人、掘金特邀作者、阿里云博客专家、51CTO特邀作者、多年架构师设计经验、腾讯课堂常驻讲师 主要内容：Java项目、Python项目、前端项目、人工智能与大数据、毕业设计、简历模板、学习资料、面试题库、技术互助 收藏点赞不迷路 关注作者有好处 私信获取源码 项目编号：BS-PT-106 一，环境介绍语言环境：Java: jdk1.8 数据库：Mysql: mysql5.7 应用服务器：Tomcat: tomcat8.5.31 开发工具：IDEA或eclipse 开发技术：SSM框架+JSP+协同过滤算法+地图定位系统等 二，项目简介信息技术的应用虽然说带来了很多的便宜，但同时也带了信息和数据的大爆炸。在信息匮乏的时代，人们期望获得更多的信息和数据，以便了解这个世界，但是真正到了数据大爆炸的时代，人们又往往无所适从，不知道怎么才能过滤掉那些对自己无用的数据，获得有效的信息。本次课题所研究的就是基于用户偏好来实抽电影推荐系统，其主要是根据用户在平台上的操作行为记录，来根据设定的相关规则判断用户的喜好，根据协同过滤算法来给用户进行相应的数据推荐。同时在用户无操作数据记录时，也就是常用的数据静默时，也根据相应的规则给用户推荐一些电影数据，以期为用户找到一些对自己有用的数据。 本系统主要基于Java开发技术平台来实现系统的开发，使用了SSM框架来完成电影推荐系统的后台服务接口开发和业务逻辑处理，使用JSP页面完成数据的展示，利用AJAX和JQUERY来实现人机交互的异步数据请求。具体的数据推荐主要使用协同过滤算法的数据模型进行数据推荐。系统整体功能完整，界面美观大方，人机交互效果好。 根据市场调研和用户走访，并进行整理分析，得知本次设计实现的电影推荐系统用户一共有二类，一是前端用户，一类是管理员用户。这二类用户的角色和操作功能权限各不不同，下面通过用例图的方式来进行展示。 前端用户的用例图如下图1所示。
图1 前端用户用例图 前端用户用例描述：前端用户注册登陆后，主要可以实现在线浏览新闻信息、分类浏览电影信息、电影影评信息、用户发布的电影攻略信息，查看推荐的电影信息，在线进行反馈留言，预定电影票等，同时在个人中心处可以发布电影攻略，查看个人的收藏信息、预定信息等。 管理员用户的操作用例图如下图2所示：
图2 管理员用户用例图 管理员用户用例图描述：管理员登陆电影推荐系统，主要的职责是对平台的基础信息进行管理，包含前端注册的用户信息管理、轮播图管理、资讯管理、电影管理、类型管理、电影说评管理、投诉管理、预定订单管理、攻略管理等。 在对整个电影推荐系统做了充分的需求分析和架构设计之后，最终确定了本次开发设计的电影推荐系统要实现的功能目标，下面分别展示一下电影推荐系统的前端用户功能架构和后台管理的功能架构图。前端用户的功能具体展示如下图3所示。
图3 前端用户功能结构图 前端用户的功能模块介绍： （1）注册登录功能模块设计 前端用户进行相关操作时需要进行注册线上会员，填写个人账户信息和个人信息后注册成功后即可登陆。 （2）个人信息管理功能模块设计 用户登录系统后，可以进入系统管理来修改密码，输入旧密码、新密码并确认密码，保证新密码和确认密码一致的情况下则修改成功，如果不一致则就修改失败。 （3）信息浏览功能模块 前端用户可以在电影平台上浏览电影信息、相关电影说评信息、电影攻略信息、行业资讯信息等，可以查看具体各类信息的详情，并可以在线评论，对于喜欢的电影或电影说评，可以进行收藏。 （4）在线预定功能模块 前端用户登陆后，进入电影介绍的详情页面，可以点击预定按钮，在线预定电影，并可以在个人中心中管理自己预定的电影，待后台管理员审核通过后即算预定成功。 （5）电影攻略模块 用户可以在线进行发贴，书写自己所观看的电影的感受，或某个电影的攻略信息，并可以在线管理自己的贴子。 （6）个性化推荐模块 电影管理平台系统，会根据用户的浏览记录，进行相关的计算，采用协同过滤算法来给不同的用户进行相应的信息推荐，目前的数据模型主要是依据用户浏览的电影特点，匹配相关性的电影信息，在首页推荐模块进行推荐展示。 （7）全文检索模块 在电影管理平台系统中，前端用户可以根据相关的关键词来进行搜索，会全文匹配电影信息，电影说评信息等，根据标题说明来进行模糊匹配，将查找到的信息展现出来。 （8）投诉建议 除了提供用户的在线评论和收藏等互动功能外，还提供了投诉建议模块，以便用户及时反馈相关的意见，由后台管理员进行处理。 后端用户的功能模块介绍： （1）个人信息管理：管理员登陆后台可以对个人的信息进行相应的管理操作。 （2）用户管理：管理员可以对前端注册的用户信息进行相应的管理操作。 （3）轮播图管理：对前端首页的轮播图信息进行相应的管理操作，可根据需求进行轮播图的更换等。 （4）行业资讯管理：主要管理和发布电影行业的相关动态新闻信息。 （5）电影管理：主要管理发布的电影信息，详细的介绍电影的价格，特点等，并在后台指定电影所放映的影院地图定位坐标，这使得前端用户可以直接通过百度地图定位电影院所在位置。 （6）电影说评管理：主要管理电影附近的相关电影说评信息，完成电影说评信息的增删改查操作。 （7）订单管理：主要管理前端用户的下单信息，前端会员预定电影后，需要管理员在后台进行审核，生效后方可使用。 （8）攻略管理：主要管理前端电影会员用户发布和电影攻略信息。 （9）投诉建议：对前端用户发布的投诉建议信息进行相关的管理操作。 三，系统展示 3.1前台功能模块的展示 3.1.1 注册登陆电影推荐系统为前端用户提供了注册和登陆的基本功能，这也是为了确保用户进行在线预定等的数据安全和数据的对应，用户登陆的基本流程如下图3.1所示。
图3.1 登陆流程图 用户登陆的操作界面如下图5.2所示：
图3.2 用户登陆 登陆的前提是要有注册的账户信息，用户注册的基本流程如下图3.3所示：
图3.3 前端用户注册流程图 电影推荐系统的前端用户注册的界面如下图3.4所示：
图3.4 前端用户注册界面 3.1.2 电影分类浏览用户登陆系统后可以在线查看发布的电影信息，平台提供了按电影名称进行全局搜索的操作，同时可以根据电影类型分类查询，具体展示如下图35所示。 图3.5 电影分类浏览 用户点击感兴趣的电影后会进入电影的详情界面，在电影的详情里可以查看这部电影相关具体的信息（导演、编剧、主演、简介等），还可以进行在线预定、收藏、评论留言等互动操作，具体如下图3.6所示。
图3.6 电影详情浏览 3.1.3 电影推荐用户登陆系统后,系统可以根据用户的一些操作行为数据记录并基于系统所用的协同过滤算法功能来为用户推荐相关的电影信息并直接在系统的首页进行展示，具体展示如图3.7所示。
图3.7 电影推荐 3.1.4 行业新闻浏览用户登陆系统后可以点击博客文章进入博客模块，用户可以在线查看用户发布的博客信息，具体展示如下图4.8所示。
图3.8 电影新闻浏览 3.1.5 观影攻略用户登陆系统后可以点击电影攻略，查看每个用户分享的电影攻略信息，用户可以自己在平台发布每个电影观看的攻略详情，具体展示如下图3.9所示。
图3.9 电影攻略 3.1.6 电影说评电影说评主要展示一些名人大伽对于电影的一些评析信息，用户在些模块可以进行查看，电影说评具体实现具体如下图3.10所示。
