public class FirstController implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest arg0,
            HttpServletResponse arg1) throws Exception {
        // TODO Auto-generated method stub
        
        //创建ModelAndView对象
        ModelAndView mav = new ModelAndView();
        //向模型对象中添加数据
        mav.addObject("msg","first springmvc");
        // 设置逻辑试图名
        mav.setViewName("first");
        
        
        return mav;
    }

}

    <!-- 配置处理器Handle-->
    <bean name="/firstController" class="com.inspur.controller.FirstController">
    </bean>
    <!-- 处理映射器，将处理器Handle的name作为url进行查找 -->
    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
    <!-- 视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="ViewClass" value="org.springframework.web.servlet.view.JstlView"></property>
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>

3.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>
  <servlet>
      <!--  配置前端过滤器 -->
      <servlet-name>springmvc</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <!-- 表示容器再启动的时候立即记载Servlet -->
       <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
      <servlet-name>springmvc</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>
 
  
      
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

4.

springmvc-servlet.xml的路径必须在WEB-INF下面，如果不在这里，可以在web.xml中servlet中配置

 <!-- 初始化加载配置文件  -->
    <init-param>
        <param-name>ContextConfigLocation</param-name>
        <param-value>classpath:springmvc-config.xml</param-value>
    </init-param>
