css
层叠样式表(英文全称：Cascading Style Sheets)是一种用来表现HTML（标准通用标记语言的一个应用）或XML（标准通用标记语言的一个子集）等文件样式的计算机语言。CSS不仅可以静态地修饰网页，还可以配合各种脚本语言动态地对网页各元素进行格式化
bootstrap
Bootstrap是Twitter推出的一个用于前端开发的开源工具包。它由Twitter的设计师Mark Otto和Jacob Thornton合作开发,是一个CSS/HTML框架简洁、直观、强悍的前端开发框架，让web开发更迅速、简单https://v3.bootcss.com/下载文件
（1）复制bootstrap的内容到webapp文件夹 （2）在页面引入 （3）使用项目访问路径 ${path} （4）设置spring-mvc的静态资源拦截规则
springmvc配置
<mvc:resources location="/css/" mapping="/css/**" />
<mvc:resources location="/images/" mapping="/images/**" />
<mvc:resources location="/js/" mapping="/js/**" />
<mvc:resources location="/fonts/" mapping="/fonts/**" />
可以去网站复制粘贴模板

pagehelper分页插件介绍
针对Mybatis提供分页插件，将分页查询简化依赖配置 pagehelper配置插件plugin
导入依赖pom.xml
<dependency>
<groupId>com.github.pagehelper
</groupId>
<artifactId>pagehelper
</artifactId>
<version>5.0.0
</version>
</dependency>
配置applicationContext.xml
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.dsf.domain"/>
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<value>
reasonable=true
helperDialect=mysql
</value>
</property>
</bean>
</array>
</property>
</bean>
controller层代码
由于拦截器会使用全查语句拼接limit分页，所以每个sql建议不要写 ; 先调用PageHelper.startPage(currPage,pageSize)再调用全查，才能自动分页
@RequestMapping(path
= "/pageUI",method
= RequestMethod
.GET
)
public String
pageUI(Model model
, Integer currPage
, Integer pageSize
){
l
.info("page currPage="+currPage
);
l
.info("page pageSize="+pageSize
);
if (currPage
==null
){
currPage
=1;
}
if (pageSize
==null
){
pageSize
=5;
}
PageHelper
.startPage(currPage
,pageSize
);
List
<Department> list
=service
.findAllDepartments();
PageInfo
<Department> pi
=new PageInfo<>(list
);
model
.addAttribute("pi",pi
);
return "list_v3";
}
list_v3.jsp(上面)
要导入标签库 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
