本文介绍了一个基于SpringMVC与MyBatis框架整合的项目配置过程，包括pom文件依赖管理、web.xml配置、Spring核心配置文件applicationContext.xml及SpringMVC配置文件dispatcherServlet.xml等内容。

maven部分，pom文件

web.xml配置

<!--1、启动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>
<!--2、SpringMVC的前端控制器 拦截所有请求-->
<servlet>
  <servlet-name>springDispatcherServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:dispatcherServlet.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>springDispatcherServlet</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

<!--3、字符编码过滤器-->
<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请求转为制定的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>

applicationContext.xml
