<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>videoTS</display-name>
  
  <servlet>
  	<servlet-name>mvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
    	<param-name>contextConfigLocation</param-name>
    	<param-value>classpath:mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>mvc</servlet-name>

  </servlet-mapping>
  
  
  <welcome-file-list>
    <welcome-file>index.html</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-app>

3. mvc.xml配置：注解HandlerAdapter

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
   
	<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>	    
	    <property name="prefix" value="/WEB-INF/jsp/"/>	    
	    <property name="suffix" value=".jsp"/>
	</bean>

	<context:component-scan base-package="cn.test.controller"/>
</beans>

4. helloCpntroller.java

package cn.test.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;


@Controller
public class helloController{
	@RequestMapping("/hello")
	public ModelAndView hello(HttpServletRequest req, HttpServletResponse resp){
		ModelAndView mv = new ModelAndView();
		mv.setViewName("hello");
		mv.addObject("msg", "dddd");
		return mv;
	}
}

5. 添加hello.jsp.........
