总的步骤如下:
1：新建工程加入ssm整合依赖，另外需要加上servlet-api.jar，加上jstl，mysql,c3p0,PageHelp的依赖
2：在web.xml中配置
①拦截编码内容
②能够支持servlet运行的
③能够将put delete转换为post的配置
④将后面的spring配置文件加入的ioc容器中
⑤监听器
3.新建springmvc的配置文件（DispatcherServlet-servlet.xml）
①扫描包（可以配置只扫描控制层的包）
②配置视图解析器(IRVR)
③加入能够让项目识别外部资源文件的配置
4.新建spring的配置文件（applicationContext.xml）
①扫描包（扫描除了控制层以为的包）
②新建外部文件 编写连接数据库的内容
③在spring配置文件中引入外部文件，并编写DataSources连接数据库的配置
④配置SqlSessionFactoryBean
⑤配置接口对应的隐射sql
⑥配置事务相关
⑦配置面向切面相关内容配置
5.新建static文件夹，新建mybatis-config.xml
static文件夹：存放XXXmapper.xml
mybatis-config.xml：加入类的别名处理器、加入PageHelp配置

<!--表示里面含有index.jsp等页面，运行工程时默认显示顺序第一的页面，在这里面也就是index.jsp页面-->
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
<!--3.字符编码顾虑器,需要在其他过滤器之前-->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceRequestEncoding</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>forceResponseEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--4.使用rest风格的URI,将页面普通的post请求转为指定的delete或者put请求-->
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--2. springmvc前端控制器，拦截所有请求-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--1. 配置spring容器-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
在WEB-INF目录下新建DispatcherServlet-servlet.xml文件
