SSM整合+视频网站开发

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

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

public String test(){

returnTEST;

}

3.2.5运行SpringMVC环境结果

Ok springMVC环境搭建成功

3.3Spring整合Mybatis

3.3.10 运行结果解决406

使用SpringMVC返回json格式,返回状态406,表示SpringMVC没有集成JSON转换器

解决办法:

<!-- 避免IE执行AJAXʱ,返回JSON出现下载文件 -->

<bean id="mappingJacksonHttpMessageConverter"

class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

</list>

</property>

</bean>

<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

<property name="messageConverters">

<list>

<ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->

</list>

</property>

</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-ddHH: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-ddHH: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-ddHH: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>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>ͼƬ</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

</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>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!");

returnLOCAVIDEO;

}

}

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(intid, HttpServletRequest request) {

VideoInfo videoInfo = videoInfoService.getVideoInfo(id);

request.setAttribute("videoInfo", videoInfo);

returnVIDEODETAILS;

}

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, intpageIndex) {

Page page = PageHelper.startPage(pageIndex, 2);

request.setAttribute("listVideo", videoInfoService.getVoideAll(null));

request.setAttribute("pageSize", page.getPages());

returnINDEXVIDEO;

}

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}">βҳ</a>
