课程目标

使用SpringMVC+Mybatis+Spring+Maven进行分模块整合 简单实现视频网站开发

一、项目演示

视频网站构建模式

分为:自建模式和第三方模式

自建模式:需要自己搭建服务器、解决CDN加速问题、提高SDK、防盗链等问题

第三方模式:使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 蚂蚁课堂网站视频架构

二、使用技术

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—服务层

itmayiedu-web—web层

三、项目整合

3.1 itmayiedu-parent父工程添加依赖

	</bean>

Ok SpringMVC+Mybatis+Spring+Maven环境整合成功!

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>
	<!--使用监听加载log4j的配置文件 -->
	<listener>
		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
	</listener>

使用API

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

四、后台管理

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="c" uri="http://java.sun.com/jsp/jstl/core"%>

4.2 实现后台视频查询页面

4.2.1查询jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<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="locaAddVideo">添加资源</a>
		<table style="BORDER-COLLAPSE: collapse; text-align: center;"
			borderColor=#000000 height=40 cellPadding=1 width="70%"
			align="center" 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="${listVideoInfo}" var="p">
					<tr style="font-size: 18px">
						<td><img alt="" width="150px;" height="150px;"
							src="/static/imgs/${p.videoUrl}"></td>
						<td>${p.videoName}</td>
						<td>${p.typeName}</td>
						<td><a href="videoDetails?id=${p.id}" 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="selectAll" parameterType="com.itmayiedu.entity.VideoInfo"

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

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

4.3.3 后端代码上传文件

@RequestMapping("/addVideo")
	public String addVideo(@RequestParam(value = "file", required = false) MultipartFile file, VideoInfo videoInfo,
			HttpServletRequest req, HttpServletResponse res) {
		try {
			// 获取当前上下文
			String path = req.getSession().getServletContext().getRealPath("/static/imgs");
			// 文件名称
			String newName = System.currentTimeMillis() + ".png";
			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("result", "封面上传成功!");
			return "redirect:/videoManag";
		} catch (Exception e) {
			log.error(e);
			req.setAttribute("result", "上传失败!");
			return LOCAVIDEO;
		}
	}

4.4 视频详情页面

4.4.1视频详情页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<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("/videoDetails")
	public String videoDetails(int id, HttpServletRequest request) {
		VideoInfo videoInfo = videoInfoService.getVideoInfo(id);
		request.setAttribute("videoInfo", videoInfo);
		return VIDEODETAILS;
	}

4.6静态资源访问404原因

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

4.7整合pagehelper分页查询

4.7.1 将pagehelper版本修改为3.6.4

4.7.2 新增mybatis-config.xml文件

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

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

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

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

<property name="dataSource" ref="dataSource" />

<!-- 自动扫描mapping.xml文件 -->

<property name="mapperLocations" value="classpath:mappings/*.xml"></property>

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

</bean>

4.7.4 Java代码使用

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

4.7.5 前端代码

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