本篇文章为大家展示了如何在Springboot项目利用video标签实现一个视频播放功能,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
1.首先引入pom文件: pom.xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.5.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.wulaobo</groupId> <artifactId>excellentcourse_springboot</artifactId> <version>0.0.1-SNAPSHOT</version> <name>excellentcourse_springboot</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <!-- pagehelper --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.2.5</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.0.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.12</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.wulaobo.ExcellentcourseSpringbootApplication</mainClass> </configuration> </plugin> </plugins> </build> </project>
video 元素支持三种视频格式: MP4, WebM, 和 Ogg:
MP4 = 带有 H.264 视频编码和 AAC 音频编码的 MPEG 4 文件
WebM = 带有 VP8 视频编码和 Vorbis 音频编码的 WebM 文件
Ogg = 带有 Theora 视频编码和 Vorbis 音频编码的 Ogg 文件
我使用的是MP4格式的视频,video标签对MP4视频的编码格式有要求,所以使用 格式工厂 来对视频进行编码.
下载链接:点我下载
2.下载安装之后点击格式工厂
3. 点击 -> MP4
4. 点击输出配置,配置视频的编码格式
5.设置视频编码:
注意:视频编码要设置为 AVC(H264) ,音视频编码要设置为 AAC
6. 然后点击确定 ->添加文件 ->确定 ->开始就可以了
切记:上传视频时,一定要上传使用格式工厂转码后的视频,否则video标签不能播放视频
3.视频播放功能的具体实现:
1.点击播放按钮如下图所示:
2.点击播放按钮进入VideoController获取文件的存放路径,代码如下所示:
package com.wulaobo.controller; import com.github.pagehelper.PageHelper; import com.github.pagehelper.PageInfo; import com.wulaobo.bean.Video; import com.wulaobo.service.VideoService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.multipart.MultipartFile; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.*; import java.net.URLEncoder; import java.sql.Timestamp; import java.text.DecimalFormat; import java.util.List; import java.util.Random; @Controller public class VideoController { @Autowired private VideoService videoService; //点击播放按钮,开始播放视频 @GetMapping(value = "/videoPlayByIdAndAdmin") public String videoPlayByIdAndAdmin(Integer id,ModelMap model) { Video video = videoService.getVideoById(id); model.addAttribute("title",video.getTitle()); model.addAttribute("path",video.getPath()); return "videoPlay"; } }
3.controller层调用service层: VideoServiceImpl.java
package com.wulaobo.service.impl; import com.wulaobo.bean.Video; import com.wulaobo.mapper.VideoMapper; import com.wulaobo.service.VideoService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class VideoServiceImpl implements VideoService { @Autowired private VideoMapper videoMapper; @Override public Video getVideoById(Integer id) { return videoMapper.getVideoById(id); } }
4.service层调用dao层:VideoMapper.java
package com.wulaobo.mapper; import com.wulaobo.bean.Video; import java.util.List; public interface VideoMapper { Video getVideoById(Integer id); }
5.mybatis配置文件:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.wulaobo.mapper.VideoMapper"> <select id="getVideoById" parameterType="Integer" resultType="video"> select * from t_video where id=#{id} </select> </mapper>
6.获取到视频存放路径之后,跳转到视频播放页面:VideoPlay.html
<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>在线视频播放</title> <link rel="shortcut icon" th:href="@{/favicon.ico}" rel="external nofollow" /> <link rel="stylesheet" th:href="@{/static/bootstrap/css/bootstrap.min.css}" rel="external nofollow" > <script th:src="@{/static/js/jquery-3.3.1.min.js}"></script> <script th:src="@{/static/bootstrap/js/bootstrap.min.js}"></script> </head> <body> <!--<div th:replace="header::header1"></div><br/><br/><br/>--> <div class="text-right "> <span class="glyphicon glyphicon-hand-right" aria-hidden="true"></span> <a th:href="@{getAllNews}" rel="external nofollow" >点此返回主页</a> </div> <div class="panel panel-default"> <div class="panel-body" align="center"> <div id="a1" align="center" th:text="${title}"></div><br/> <video width="600" height="400" align="center" controls> <source th:src="@{'/upload/'+${path}}" type="video/mp4"> 您的浏览器不支持 HTML5 video 标签。 </video> </div> </div> </body> </html>
