写程序，大多的配置让人很头痛。有了注解功能，写起来就方便了许多。

在上个springmvc中

  1. control换成

package com.conntrol;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;


@Controller
public class HelloConntrol {
	@RequestMapping(value="/hello.do")
	public String hello(String name,Model model){
		
		System.out.println(name);
		model.addAttribute("hello", name);
		
		return "index";
	}
}

2.在springmvc-servlet.xml中改为：

<?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:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">
	
	<!-- 注解驱动 -->
	<mvc:annotation-driven/>
	<!-- 注解扫描器 -->
	<context:component-scan base-package="com"/>
	
	<!-- 视图解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/view/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
</beans>
