项目介绍
本项目旨在为我的世界基岩版私服搭建一个可视化的后台管理系统，通过 LiteloaderBDS 插件实时收集游戏内数据，并将其存储在轻量级数据库 SQLite 中。后端采用 Spring Boot 和 MyBatis 技术栈实现 RESTful API，前端采用 Vue 框架、Element-UI Plus 组件库以及 Three.js WebGL 库实现三维可视化界面

技术选型和原因
本项目采用的部分技术栈：
- LiteloaderBDS：跨语言 BDS 插件加载器（适用于我的世界基岩版服务器）
- SQLite：轻量级数据库，减少部署难度
- MyBatis：持久层框架
- Spring Boot：简化 Spring 应用的初始搭建及开发
- Spring MVC：基于 Java 的 Web 框架，支持 RESTful API 设计
- Vue：渐进式 JavaScript 框架，构建用户界面
- Element-UI Plus：基于 Vue 的组件库
- Three.js：WebGL库，实现三维可视化
搭建步骤
- 购买云服务器实例
- 安装部署 BDS
- 安装部署 LiteloaderBDS
- 编写 LiteloaderBDS 脚本插件（将数据存入 SQLite 数据库）
- 插件测试
- 插件部署
- 使用 IntelliJ IDEA、Hbuilder X，分别创建 Spring Boot 和 Vue 项目，编写后端和前端
- 网站测试
- 网站部署
库表设计
- 位置表
- 在下面表中，出现重复位置的概率很大，因此设计了位置表，节省占用空间
- 在未来，位置表中可以添加访问次数这样的列，用于统计玩家活跃地区
- 位置表的 x，y，z 和维度 id 上了索引，便于查找
- 容器表
- 包括玩家背包、末影箱和地图上的容器方块
- 玩家表
- 玩家有位置和容器
- 历史位置表
- 历史位置有玩家和位置
- 容器方块表
- 容器方块有容器和位置
- 破坏放置表
- 破坏放置有玩家和位置
- 攻击实体表
- 攻击实体有玩家和位置
插件说明
BB_Data.js 的代码内容分为四大部分：事件监听、定时任务、辅助函数、创表语句
其中，增删改查逻辑集中在事件监听、定时任务和辅助函数部分
被监听的事件：
- 玩家进入世界
- 玩家离开世界
- 玩家打开容器
- 玩家关闭容器
- 玩家发送消息
- 玩家破坏放置
- 玩家攻击实体
由于 SQLite 对并发修改支持不佳，代码中的 SQL 执行语句偶尔会出现异常；但总的来说，这仅仅会导致很小一部分行为没有被记录，所以我没有加锁来改善这一问题（加锁影响性能）
有一些测试用的打印语句，可以删掉
后端说明
后端采用了传统的 Spring Boot + MyBatis 技术栈
相对于持久层设计，简化了数据模型（去除了所有的外键部分），便于前端拿取数据后直接使用
前端说明
风格为选项式 API，单页面应用（SPA），面向组件设计，解耦较好
多种布局样式，包括传统、绝对位置和 Flex 布局
使用了路由管理
其中一个 svg 图标（ChatGPT），直接封装为组件使用了，在代码中省略
部署说明
后端打包成 JAR 文件，在服务器用命令行执行
前端打包成静态资源，上传到服务器的 Nginx 服务目录，启动 Nginx

欢迎！(ノ^o^)ノ<br />
<br />
请仔细阅读以下说明：<br />
<br />
须点击左侧二维地图<font color="red">两次</font>以设置三维地图中相机位置和朝向（相机高度会与箭头最近方块持平）<br />
<font color="red">点击完成后，</font>可拖动出现的黑色滑条来调整相机的高度（你现在还看不到它）<br />
此后，在三维地图中，点击方块以查看它的坐标和内容<br />

项目总结
- 运行时占内存的大头是 LiteloaderBDS，项目的逻辑集中在插件和前端部分
- 后端的安全性和容错性不足
- 前端的地图相机选点功能不够易用，需要改进
- 数据库部分并发处理不好，可能需要重新设计
