　　8.Eclipse创建一个动态web项目，将其中的web.xml配置文件拷贝到maven项目中，注意修改项目名称。

二、添加xml配置

　　1.web.xml配置

<?xml version="1.0" encoding="UTF-8"?>

  <display-name>mybatis-spring02</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>

  <!-- web容器启动时根据contextConfigLocation配置的路径读取Spring的配置文件，然后启动Spring -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  </listener>
  <!-- 配置Springmvc所有的请求都要通过DispatcherServlet -->
  <servlet>
      <servlet-name>springmvc</servlet-name>

      </init-param>
      <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
      <servlet-name>springmvc</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 编码utf-8 -->
  <filter>
      <filter-name>SpringEncodingFilter</filter-name>
      <filter-class>

      </init-param>
  </filter>
  <filter-mapping>
