一.SSM框架整合
把框架进行整合在一个项目
1.导jar包
2.web-xml
3.框架的xml
4.实体类
5.dao的xml及接口方法
6.servlce类 @Service注解
@Resource
接口方法 get set + return
7.controller
@Controller
@RequestMapping("xxx")
里面用到service，@Resource注解+get+set
写个返回值ModeAndView 方法给注解@RequestMapping("")，查过结果返回ModeAndView，存入mv.addObject(集合)，跳转mv.setViewName("cg")

二.BootStrp
二 BootStrp
1.自适应布局
传统自适应
<Style>
//大屏幕1024分辨率下
@media all and(min-width:1024px){
样式
}
//小屏幕分辨率下
@media all and(max-width:1023px)and(min-width:768px){
样式
}
//更小屏幕分辨率下
@media all and(max-width:767px){
样式
}
</Style>
BootStrp自适应作用
十二分三拦设置
1.把所有css放进去
2.导了一句话，使用所有的屏幕信息
3.导入BootStrp.css
4. class = "container"
Class="row" BootStrp提供
class="col-md-3"代表小屏幕
class="col-xs-4"大屏幕
实例：
<html>
<head lang="en"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0/>
<link href="css/bootstrap.css" rel="stylesheet"> </head>
<body> <h1>这是一个Bootstrap框架的最基本HTML模板</h1> <script src="js/jquery-1.12.4.js"></script> <script src="js/bootstrap.js"></script>
</body>
</html>
BootStrp自带css样式
BootStrp自带js样式
BootStrp其他插件
