     看示例:

1、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	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_2_5.xsd">
  <display-name></display-name>	
  
  <servlet>
  	<servlet-name>test</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>test</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

2、spring-servlet.xml

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd


http://www.springframework.org/schema/context


http://www.springframework.org/schema/context/spring-context-3.0.xsd


http://www.springframework.org/schema/aop


http://www.springframework.org/schema/aop/spring-aop-3.0.xsd


http://www.springframework.org/schema/tx


http://www.springframework.org/schema/tx/spring-tx-3.0.xsd


http://www.springframework.org/schema/mvc


http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd


http://www.springframework.org/schema/context

			http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    <!--
        使Spring支持自动检测组件,如注解的Controller
    -->
  	<context:component-scan base-package="cn.com.yy.controller"/>
  	
  	<!-- 开启注解配置 -->
   	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
   	<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
   
   	<!-- 支持JSP JSTL的解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    	<property name="prefix" value="/WEB-INF/page/"/>
    	<property name="suffix" value=".jsp"/>
     </bean>
</beans>

3、Controller

package cn.com.yy.controller;

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

@Controller
public class UserController {

	@RequestMapping(value="/addUser",method=RequestMethod.GET)
	public ModelAndView addUser(){
		String msg = "this is a add user page";
		return new ModelAndView("add","msg",msg);
	}
	
	@RequestMapping("/removeUser")
	public ModelAndView removeUser(){
		String msg = "this is a remove user page";
		return new ModelAndView("remove","msg",msg);
	}
}

4、页面

       add.jsp

  <body>
   	${msg }
  </body>

5、效果

      

    上述就是SpringMVC之简单的注解使用。
