web.xml 简单配置

   <servlet-name>springMVC</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:config/spring-servlet.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>

<!--springMVC 默认解决乱码过滤器配置-->

  <filter>
   <filter-name>springMVCEncoding</filter-name>
   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
   <init-param>

   </init-param>
    <init-param>
   <param-name>forceEncoding</param-name>
   <param-value>true</param-value>
   </init-param>
  </filter>
   <filter-mapping>
   <filter-name>springMVCEncoding</filter-name>
   <url-pattern>/*</url-pattern>
   </filter-mapping>
