使用工具：
Eclipse
MySQL
tomcat7.0
使用框架：
springMvc
spring
mybits
1.我们先搭建出web项目，如 [图1] 点击Finish
图1
2.搭建之后如【图2】，我们添加了tomcat7.0的包，同时new出一个index.jsp
图2
图2中：
src文件夹存放java代码，以及配置文件；
WebContent文件夹下面存放用户可访问资源；
web.xml存放配置文件，并且项目启动时最先访问的就是这个配置文件；
3.我们需要添加jar包到WebContent/WEB-INF/lib里面
ssm所需jar包 密码：bx2z
4.接下来就是在web.xml对spring，springmvc的支持
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>mybolg</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<!-- 指定spring文件位置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- spring监听 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 前端控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
4.根据上面classpath产生了两个文件applicationContext.xml , springmvc.xml
classpath即是类路径的意思，后缀为.java的源程序编译成功之后会生成后缀为.class的类文件。
applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

<!--引入db.properties文件 -->

<!-- 数据库连接池 -->

destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />

<property name="dataSource" ref="dataSource" />
</bean>
<!-- 开启注解 -->

</beans>
springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>

<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
5.根据上面两个配置文件产生了两个必须的文件
sqlMapConfig.xml
<?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>
<settings>
<!-- 打印查询语句 -->
<setting name="logImpl" value="STDOUT_LOGGING" />
<setting name="mapUnderscoreToCamelCase" value="true" />
</settings>
<!-- 设置别名 -->
<typeAliases>
<!-- 2. 指定扫描包，会把包内所有的类都设置别名，别名的名称就是类名，大小写不敏感 -->
<package name="seience.havelook.pojo" />
</typeAliases>
</configuration>
db.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybolg?characterEncoding=UTF8
jdbc.username=root
jdbc.password=root
至此框架搭起来了
