音乐管理系统 SpringBoot + vue

文章目录


也算是进行了半个学期,跟着老师讲的进行

后端使用SpringBoot 前端 vue + layui
jdk 18

项目地址:gitee


1、简要介绍

只有管理端,但是对用户端的判断功能在数据库中已经体现,

实现了mp3音频文件和图片文件的上传,原理是存储在静态资源中,数据库中存的也是路径而已

以下为部分截图,整体风格亦是如此



2、数据库设计

sql 复制代码
CREATE TABLE `role`  (
  `id` int NOT NULL AUTO_INCREMENT COMMENT '角色id',
  `role_name` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '角色名称',
  `role_status` int NULL DEFAULT NULL COMMENT '角色状态  0 不可用  1 可用',

  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;


CREATE TABLE `singer`  (

  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 14 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;

3、解决的问题

1、图片和音频的上传和存储

首先肯定是要有一个对于存储文件的配置,然后,在前端发送的时候,注意使用
post + headers: { 'content-type': 'multipart/form-data' } 的格式,

java 复制代码
package com.whd.system.controller;

import com.github.pagehelper.util.StringUtil;
import com.whd.system.common.AxiosResult;
import com.whd.system.mapper.SysUserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.Filter;
import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.IOException;
import java.time.LocalDate;
import java.util.UUID;

@RestController
@RequestMapping("/fileup")
public class FileUpController {

    public static final String UPLOAD_PATH = "F:\\javaweb\\study\\spingBootMaven\\src\\main\\resources\\upload\\";

    @PostMapping("/image")
    public AxiosResult<String> upload(@RequestParam(value = "name") String name,  MultipartFile photo, HttpServletRequest request) throws IOException {

        if(name==null || name.equals("")){
            return AxiosResult.error("参数错误");
        }

        String extension = StringUtils.getFilenameExtension(photo.getOriginalFilename());

        String fileName = UUID.randomUUID().toString().replaceAll("-", "") + "." + extension;

        String curDateStr = LocalDate.now().toString();


        File file = new File(UPLOAD_PATH+name+"\\"+ curDateStr);
        if (!file.exists()) {
            file.mkdirs();
        }

        photo.transferTo(new File(UPLOAD_PATH +name+ "\\" + curDateStr + "/" + fileName));

        return AxiosResult.success(name+ "\\" + curDateStr + "/" + fileName);
    }

    @PostMapping("/video")
    public AxiosResult<String> uploadViedo(@RequestParam(value = "name") String name,  MultipartFile video, HttpServletRequest request) throws IOException {

        name+="\\viedo";

        if(!video.getContentType().equals("audio/mpeg")) {
            return AxiosResult.error("只允许上传mp3格式的音频文件");
        }

        String extension = StringUtils.getFilenameExtension(video.getOriginalFilename());

        String fileName = UUID.randomUUID().toString().replaceAll("-", "") + "." + extension;

        String curDateStr = LocalDate.now().toString();
        System.out.println(UPLOAD_PATH+name+"\\"+ curDateStr);

        File file = new File(UPLOAD_PATH+name+"\\"+ curDateStr);
        if (!file.exists()) {
            file.mkdirs();
        }

        video.transferTo(new File(UPLOAD_PATH +name+ "\\" + curDateStr + "/" + fileName));

        return AxiosResult.success(name+ "\\" + curDateStr + "/" + fileName);
    }


}

2、分页功能

通过自定义的一个组件(当然不是我写的),在后端进行判断处理,其实没有想到那么复杂

组件如下:

javascript 复制代码
<script>
Vue.component('zpagenav', {
	template: `<nav class="zpagenav">` +
		`<ul class="page-ul">` +
		`<li v-bind:key="index" v-for="(item,index) in pageList" v-bind:class ="item.class" @click.stop="setPage(item)" v-html="item.html">` +
		`</li>` +
		`</ul>` +
		`<span class="total">共 {{total}} 条</span>` +
		`</nav>`,
	props: {
		prevHtml: String,
		nextHtml: String,
		page: Number,
		total: Number,
		pageSize: Number,
		maxPage: Number
	},
	computed: {
		pageList: function() {
			var _this = this,
				pageList = [];
			let pageCount = Math.ceil(_this.total / _this.pageSize);
			let page = _this.page;
			let prevHtml = _this.prevHtml ? _this.prevHtml : '&lt;';
			let nextHtml = _this.nextHtml ? _this.nextHtml : '&gt;';
			let maxPage = _this.maxPage ? _this.maxPage : 9;

			let hasPrev = page > 1;
			let hasNext = page < pageCount;

			//上一页
			pageList.push({
				class: hasPrev ? '' : 'disabled',
				page: hasPrev ? page - 1 : page,
				html: prevHtml
			});

			//首页
			pageList.push({
				class: page == 1 ? 'active' : '',
				page: 1,
				html: 1
			});

			var p0 = Math.floor(maxPage / 2);
			var p1 = 1 + 2 + p0; //首页+省略至少2个页码+中间页面数的一半

			var start, end;
			if(page >= p1) {
				start = page - p0;
				//前置省略号
				pageList.push({
					class: 'dot',
					page: page,
					html: '...'
				});
			} else {
				start = 2;
			}

			var p2 = page + p0;
			if(p2 < pageCount) {
				end = p2;
			} else {
				end = pageCount - 1;
			}

			//页码列表
			for(let i = start; i <= end; i++) {
				pageList.push({
					class: page == i ? 'active' : '',
					page: i,
					html: i
				});
			}

			if(end < pageCount - 1) {
				//后置省略号
				pageList.push({
					class: 'dot',
					page: page,
					html: '...'
				});
			}

			//尾页
			if(pageCount > 1) {
				pageList.push({
					class: page == pageCount ? 'active' : '',
					page: pageCount,
					html: pageCount
				});
			}

			//下一页
			pageList.push({
				class: hasNext ? '' : 'disabled',
				page: hasNext ? page + 1 : page,
				html: nextHtml
			});

			return pageList;
		}
	},
	methods: {
		setPage: function(item) {
			
			if(item.class == '') {
				this.$emit('pagehandler', item.page);
			}
		}
	}
});

</script>

<style>
.zpagenav {
	text-align: center;
	-webkit-user-select: none;
}

.zpagenav {
	font-family: arial;
	color: #48576a;
}

.zpagenav ul {
	display: inline-block;
	margin: 20px 20px;
	padding: 0;
}

.zpagenav ul li {
	display: inline-block;
	margin: 0;
	padding: 0 4px;
	border: 1px solid #d1dbe5;
	border-right: 0;
	background: #fff;
	font-size: 13px;
	min-width: 28px;
	height: 28px;
	line-height: 28px;
	cursor: pointer;
	box-sizing: border-box;
	text-align: center;
}

.zpagenav ul li:last-child {
	border-right: 1px solid #d1dbe5;
}

.zpagenav ul li:hover {
	color: #20a0ff;
}

.zpagenav ul li.active {
	border-color: #20a0ff;
	background-color: #20a0ff;
	color: #fff;
	cursor: default;
}

.zpagenav ul li.active:hover {
	color: #fff;
}

.zpagenav ul li.disabled {
	cursor: not-allowed;
	color: #e4e4e4;
}

.zpagenav ul li.dot {
	cursor: default;
}

</style>

使用的时候,注意引入该文件,和该文件的样式文件,然后,将这一坨复制到分页的地方

html 复制代码
      <div class="page">
        <div class="wrap">
          <zpagenav v-bind:page="page" v-bind:page-size="pageSize" v-bind:total="total" v-bind:max-page="maxPage"
            v-on:pagehandler="pageHandler">
          </zpagenav>
        </div>
      </div>

注意,在vue 的 data 中加上 page: 1, pageSize: 10, total: 0, maxPage: 5,这三个属性,

然后,就是后端处理返回数据了,正常查询结果,通过 PageHelper PageInfo进行分页处理

处理逻辑如下例子:

java 复制代码
 @PostMapping("/select/selectAllPage")
    public AxiosResult<PageResult<SongVo>> getAllSongByPage(@RequestBody PageVO pageVO){


        Integer page = pageVO.getPage();
        Integer size = pageVO.getSize();

        // 开始分页
        PageHelper.startPage(page, size);
        List<SongVo> songs=songMapper.getSongList();

        songs.forEach(song -> {
            song.setPic(PIC_URL + song.getPic());
            song.setUrl(PIC_URL + song.getUrl());
        });

        PageInfo<SongVo> pageInfo = new PageInfo<>(songs);

        //将数据封装在自己写的PageResult
        PageResult<SongVo> pageResult = new PageResult<>();
        pageResult.setPage(pageInfo.getPageNum());
        pageResult.setTotalPage(pageInfo.getPages());
        pageResult.setList(pageInfo.getList());
        pageResult.setTotal(pageInfo.getTotal());
        pageResult.setPageSize(pageInfo.getPageSize());

        return AxiosResult.success(pageResult);
    }

对于AxiosResult也是自己写的一个实体类, 用于返回信息和状态码, 具体代码可查看项目中的代码:

对于PageResult 类

java 复制代码
@Data
public class PageResult<T> {
    private int page;
    private int pageSize;
    private long total;
    private List<T> list;
    private int totalPage;
}

PageVO 类

java 复制代码
@Data
public class PageVO {
    private Integer page=1;//用户查询的第几页
    private Integer size=10;//每页展示的数量
}

4、数据返回

通过SpringBoot返回的数据类型,会自动转为json格式,但是上面所提到的AxiosResult也不是必须的,但是这样子看起来更方便,该类可以作为模板重复使用
