springmvc 注解入门

1.xxx-servlet.xml文件修改

<?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.xsd   
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop.xsd   
       http://www.springframework.org/schema/tx

       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       ">
       <!--  配置HandlerMapping  根据benaname找到对应Conntroller -->
	<!-- <bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping"></bean>
	
	<bean name="hello" class="com.springmvc.zzc.HelloController"></bean> -->
	
	<mvc:annotation-driven/><!--  mvc驱动 -->
	<context:component-scan base-package="com"/> <!-- 扫描的包 -->
	<!-- 配置视图解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	    <property name="prefix" value="/"></property> <!-- 前缀 -->
	    <property name="suffix" value=".jsp"></property> <!-- 后缀 -->
	</bean>
</beans>

2.修改控制器文件

package com.springmvc.zzc;

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

@Controller // 标注为控制器
public class HelloController2 {
	@RequestMapping(value="/hello2") // 对应映射方法（value是对应动作）
	public String hello(String hello,Model model){ // 第一个是传入的参数 ，第二个相当于固定值吧
		System.out.println("hello:::"+hello);
		model.addAttribute("q", "xxx");
		return "success"; // 跳转对应界面
	}
}
