大学学servlet这部分的老师讲了web.xml的加载过程，当时不懂也不理解，配置过程也是随意配置，后来在公司实际项目搭建项目过程，开始认识到这些问题，web.xml加载过程

context-param >> listener >> filter >> servlet

<!-- Spring和mybatis的配置文件 --><context-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:spring-mybatis.xml</param-value></context-param>

<!-- Spring监听器 --><listener>  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 防止Spring内存溢出监听器 --><listener>  <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener>

<!--中文处理过滤，如果不设计中文的处理下面这部分可以移除--><filter>  <filter-name>encodingFilter</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>forceEncoding</param-name>    <param-value>true</param-value>  </init-param></filter><filter-mapping>  <filter-name>encodingFilter</filter-name>  <url-pattern>/*</url-pattern></filter-mapping>

<!-- Spring MVC servlet --><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:spring-mvc.xml</param-value>  </init-param>  <load-on-startup>1</load-on-startup>  <async-supported>true</async-supported></servlet><servlet-mapping>  <servlet-name>springmvc</servlet-name>  <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 /表示拦截所有请求 -->  <url-pattern>/</url-pattern></servlet-mapping>
