Spring Boot音乐服务器项目-查询音乐模块

news 2025/7/31 3:47:19

一、项目架构概览

该音乐播放服务器采用经典的MVC分层架构，核心模块包括：

实体层：定义数据模型
Mapper层：数据库操作接口
Controller层：HTTP请求处理
工具层：加密、响应封装等辅助功能

项目核心功能包括用户认证、音乐上传/播放、收藏管理等，下面按分层结构详解实现逻辑。

二、接口设计

⽀持模糊查询
⽀持传⼊参数为空

请求示例

{"method": "get","url": "/music/findmusic","data": {"musicName": musicName}
}

响应示例

未给 musicName 传参时

{"status": 0,"message": "查询到了歌曲的信息","data": [{"id": 19,"title": "银河与星斗（女生版）","singer": "gaobo","url": "/music/get?path=银河与星斗（女生版）","time": "2022-03-28","userid": 3},{"id": 20,"title": "liu","singer": "bit","url": "/music/get?path=liu","time": "2022-03-28","userid": 3}]
}

给 musicName 传参时

{"status": 0,"message": "查询到了歌曲的信息","data": [{"id": 19,"title": "银河与星斗（女生版）","singer": "gaobo","url": "/music/get?path=银河与星斗（女生版）","time": "2022-03-28","userid": 3}]
}

三、Mapper层实现

使用MyBatis实现数据库操作，核心接口：

1. 查询功能Mapper

    /***根据歌曲名字，查询⾳乐* @param name* @return*/List<Music> findMusicByMusicName(String name);/**查询所有的⾳乐@return*/List<Music> findMusic();

XML映射：

    <select id="findMusicByMusicName"resultType="com.example.musicplayer.model.Music">select * from music where title like concat('%',#{musicName},'%')</select><select id="findMusic" resultType="com.example.musicserver.model.Music">select * from music</select>

四、MusicController类新增⽅法

处理HTTP请求并调用Mapper操作：

音乐查询接口

/**根据musicName查询音乐@param musicName@return*/@RequestMapping("/findmusic")public ResponseBodyMessage<List<Music>> findMusic(@RequestParam(required=false)String musicName) {List<Music> musicList = null;if(musicName != null) {musicList = musicMapper.findMusicByMusicName(musicName);}else {//默认查询全部的⾳乐musicList = musicMapper.findMusic();}return new ResponseBodyMessage<>(0,"查询到了歌曲的信息",musicList);}
