jsp页面播放优酷视频播放SSM整合视频网站开辟

利用SpringMVC+Mybatis+Spring+Maven进行分模块整合 大略实现视频网站开拓

视频网站构建模式

分为:自建模式和第三方模式

自建模式:须要自己搭建做事器、办理CDN加速问题、提高SDK、防盗链等问题

第三方模式:利用第三方云视频接口、阿里云、保利云(8毛)、乐视云(4毛G)。

讲述一下 蚂蚁教室网站视频架构

后端:SpringMVC、Spring、Mybatis

前端:jquery

itmayiedu-parent—父类工程

itmayiedu-commons—工具类

itmayiedu-entity—实体类

itmayiedu-dao—数据库访问层

itmayiedu-service—做事层

itmayiedu-web—web层

3.1 itmayiedu-parent父工程添加依赖

3.4 Spring整合log4j

3.4.1创建log4j.properties

在resources/properties下创建log4j.properties文件

### set log levels ###

log4j.rootLogger =INFO,DEBUG, stdout , R

log4j.appender.stdout = org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target = System.out

log4j.appender.stdout.layout = org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

log4j.appender.D = org.apache.log4j.DailyRollingFileAppender

log4j.appender.D.File = E://logs/log.log

log4j.appender.D.Append = true

log4j.appender.D.Threshold = DEBUG

log4j.appender.D.layout = org.apache.log4j.PatternLayout

log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

log4j.appender.E = org.apache.log4j.DailyRollingFileAppender

log4j.appender.E.File =E://logs/error.log

log4j.appender.E.Append = true

log4j.appender.E.Threshold = ERROR

log4j.appender.E.layout = org.apache.log4j.PatternLayout

log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

3.4.2web.xml加载 log4j.properties

<!--设置log4j的配置文件位置 --><context-param><param-name>log4jConfigLocation</param-name><param-value>/WEB-INF/classes/properties/log4j.properties</param-value></context-param><!--利用监听加载log4j的配置文件 --><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener>

利用API

private static Logger log = Logger.getLogger(TestController.class);

4.1 搭建编写视频查询页面

步骤:创建JSP页面,引入C标签

<%@ taglib prefix=\"大众c\"大众 uri=\公众http://java.sun.com/jsp/jstl/core\"大众%>

4.2 实现后台视频查询页面

4.2.1查询jsp页面

<%@ page language=\公众java\公众 contentType=\"大众text/html; charset=UTF-8\公众pageEncoding=\"大众UTF-8\"大众%><%@ taglib prefix=\公众c\公众 uri=\"大众http://java.sun.com/jsp/jstl/core\公众%><!DOCTYPE html PUBLIC \"大众-//W3C//DTD HTML 4.01 Transitional//EN\"大众 \"大众http://www.w3.org/TR/html4/loose.dtd\"大众><html><head><meta http-equiv=\公众Content-Type\"大众 content=\"大众text/html; charset=UTF-8\"大众><title>后台管理系统</title></head><body><center><h1>蚂蚁视频后台管理系统</h1><a href=\公众locaAddVideo\"大众>添加资源</a><table style=\"大众BORDER-COLLAPSE: collapse; text-align: center;\"大众borderColor=#000000 height=40 cellPadding=1 width=\公众70%\"大众align=\公众center\"大众 border=1><thead><tr><th>图片</th><th>视频名称</th><th>视频类型</th><th>预览视频</th></tr></thead><tbody><c:forEach items=\公众${listVideoInfo}\"大众 var=\"大众p\"大众><tr style=\"大众font-size: 18px\"大众><td><img alt=\公众\公众 width=\公众150px;\"大众 height=\公众150px;\公众src=\"大众/static/imgs/${p.videoUrl}\"大众></td><td>${p.videoName}</td><td>${p.typeName}</td><td><a href=\"大众videoDetails?id=${p.id}\"大众 style='text-decoration:none;'>预览视频</a></td></tr></c:forEach></tbody></table></center></body></html>

42.2编写XML SQL 语句

<select id=\公众selectAll\公众 parameterType=\"大众com.itmayiedu.entity.VideoInfo\"大众

resultType=\"大众com.itmayiedu.entity.VideoInfo\"大众>

select a.id as id,a.video_name as videoName, a.video_html as videoHtml ,a.video_url as videoUrl, a.video_del as videoDel

, b.type_name as typeName

from video_info as a inner join video_type as b on a.video_type_id=b.id;

</select>

4.2.3 完成页面展示

4.3 后台添加资源管理

4.3.1 创建上传资源页面

<%@ page language=\"大众java\"大众 contentType=\公众text/html; charset=UTF-8\公众pageEncoding=\公众UTF-8\"大众%><%@ taglib prefix=\公众c\"大众 uri=\公众http://java.sun.com/jsp/jstl/core\"大众%><!DOCTYPE html PUBLIC \"大众-//W3C//DTD HTML 4.01 Transitional//EN\"大众 \公众http://www.w3.org/TR/html4/loose.dtd\公众><html><head><meta http-equiv=\"大众Content-Type\公众 content=\"大众text/html; charset=UTF-8\"大众><title>添加视频资源</title></head><body><center><h1>蚂蚁视频后台添加视频资源</h1><form action=\公众addVideo\"大众 style=\"大众font-size: 14px;\"大众 method=\公众post\"大众ENCTYPE=\"大众multipart/form-data\公众><table><tr><td>视频名称:</td><td><input type=\"大众text\"大众 name=videoName></td></tr><tr><td>视频类型:</td><td><select name=\"大众videoTypeId\公众 style=\公众width: 170px;\"大众><c:forEach items=\"大众${listVideoType}\公众 var=\"大众p\"大众><option value=\"大众${p.id}\公众>${p.typeName}</option></c:forEach></select></td></tr><tr><td>优酷播放URL:</td><td><textarea rows=\"大众10\"大众 cols=\"大众30\公众 name=\"大众videoHtml\公众></textarea></td></tr><tr><td>上传封面:</td><td><input type=\"大众file\"大众 name=\"大众file\"大众></td></tr><tr> <td colspan=\"大众2\"大众><input type=\公众submit\"大众 value=\"大众提交\"大众></td></tr></table></form></center></body></html>

4.3.2 springmvc.xml文件中新增上传文件配置

<!-- 支持上传文件 --><bean id=\公众multipartResolver\"大众class=\"大众org.springframework.web.multipart.commons.CommonsMultipartResolver\"大众 />

4.3.3 后端代码上传文件

@RequestMapping(\"大众/addVideo\"大众)public String addVideo(@RequestParam(value = \公众file\公众, required = false) MultipartFile file, VideoInfo videoInfo,HttpServletRequest req, HttpServletResponse res) {try {// 获取当前高下文String path = req.getSession().getServletContext().getRealPath(\"大众/static/imgs\"大众);// 文件名称String newName = System.currentTimeMillis() + \"大众.png\公众;File targetFile = new File(path, newName);// 文件夹不存在,则创建文件夹if (!targetFile.exists()) {targetFile.mkdirs();}// 保存try {file.transferTo(targetFile);} catch (Exception e) {log.error(e);}videoInfo.setVideoUrl(newName);videoInfoService.addVideoInfo(videoInfo);req.setAttribute(\"大众result\"大众, \公众封面上传成功!\公众);return \"大众redirect:/videoManag\公众;} catch (Exception e) {log.error(e);req.setAttribute(\"大众result\"大众, \"大众上传失落败!\"大众);return LOCAVIDEO;}}

4.4 视频详情页面

4.4.1视频详情页面

<%@ page language=\公众java\公众 contentType=\"大众text/html; charset=UTF-8\"大众pageEncoding=\公众UTF-8\"大众%><!DOCTYPE html PUBLIC \公众-//W3C//DTD HTML 4.01 Transitional//EN\公众 \公众http://www.w3.org/TR/html4/loose.dtd\公众><html><head><meta http-equiv=\"大众Content-Type\公众 content=\"大众text/html; charset=UTF-8\"大众><title>${videoInfo.videoName}视频详情</title></head><body><center><h1>${videoInfo.videoName}</h1><iframe height=600 width=600 src='${videoInfo.videoHtml}'frameborder=0'allowfullscreen'></iframe></center></body></html>

4.4.2视频详情后台代码

@RequestMapping(\"大众/videoDetails\"大众)public String videoDetails(int id, HttpServletRequest request) {VideoInfo videoInfo = videoInfoService.getVideoInfo(id);request.setAttribute(\"大众videoInfo\"大众, videoInfo);return VIDEODETAILS;}

4.6静态资源访问404缘故原由

<mvc:annotation-driven /><mvc:resources mapping=\公众/static/imgs/\"大众 location=\"大众static/imgs/\"大众 /><mvc:resources mapping=\"大众/static/easyui/\公众 location=\"大众static/easyui/\"大众 /><mvc:resources mapping=\"大众/static/js/\"大众 location=\公众static/js/\公众 /><mvc:resources mapping=\"大众/static/css/\"大众 location=\"大众static/css/\"大众 />

4.7整合pagehelper分页查询

4.7.1 将pagehelper版本修正为3.6.4

4.7.2 新增mybatis-config.xml文件

<?xml version=\公众1.0\"大众 encoding=\"大众UTF-8\公众 ?><!DOCTYPE configurationPUBLIC \"大众-//mybatis.org//DTD Config 3.0//EN\公众\"大众http://mybatis.org/dtd/mybatis-3-config.dtd\"大众><configuration><!-- 配置分页插件 --><plugins><plugin interceptor=\"大众com.github.pagehelper.PageHelper\公众><!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库--> <property name=\公众dialect\公众 value=\公众mysql\公众/></plugin></plugins></configuration>

4.7.3 applicationContext-dao.xml加载mybatis-config.xml

<!-- spring和MyBatis完美整合，不须要mybatis的配置映射文件 -->

<bean id=\公众sqlSessionFactory\公众 class=\"大众org.mybatis.spring.SqlSessionFactoryBean\"大众>

<property name=\公众dataSource\"大众 ref=\"大众dataSource\公众 />

<!-- 自动扫描mapping.xml文件 -->

<property name=\"大众mapperLocations\"大众 value=\公众classpath:mappings/.xml\"大众></property>

<property name=\"大众configLocation\公众 value=\"大众classpath:spring/mybatis-config.xml\公众 />

</bean>

4.7.4 Java代码利用

@RequestMapping(\"大众/indexVideo\"大众)public String indexVideo(HttpServletRequest request, int pageIndex) {Page page = PageHelper.startPage(pageIndex, 2);request.setAttribute(\"大众listVideo\公众, videoInfoService.getVoideAll(null));request.setAttribute(\"大众pageSize\"大众, page.getPages());return INDEXVIDEO;}

4.7.5 前端代码

<a style=\"大众font-size: 20px;\"大众 href=\"大众indexVideo?pageIndex=1\"大众>首页</a><c:forEach begin=\"大众1\"大众 end=\"大众${pageSize}\"大众 var=\公众p\"大众><a style=\公众font-size: 20px;\公众 href=\"大众indexVideo?pageIndex=${p}\"大众>${p}</a></c:forEach><a style=\"大众font-size: 20px;\"大众 href=\"大众indexVideo?pageIndex=${pageSize}
