使用 idea 编辑器 + Maven + spring + spring MVC 做一个简单web访问功能，并记录一下其中的步骤。

1.从pom.xml配置Maven文件开始

2.web.xml

3.springmvc-config.xml

<?xml version="1.0" encoding="UTF-8" ?>

<beans xmlns="http://www.springframework.org/schema/beans"

                           http://www.springframework.org/schema/context/spring-context-2.5.xsd

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

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

    <!--启用spring的一些annotation-->

    <context:annotation-config/>

    <!--自动扫描com.zbt.controller-->

    <context:component-scan base-package="com.springdemo.controller"/>

    <!--配置注解驱动可以将request参数绑定到controller参数上-->

    <mvc:annotation-driven/>

    <bean 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>

        <property name="suffix" value=".jsp"></property>

    </bean>

</beans>

4.controller

package com.springdemo.controller;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

@RequestMapping("/student")

public class StudentController {

    private static final Log logger = LogFactory.getLog(StudentController.class);

    @RequestMapping("/hello")

    public String sayHi(){

        logger.info("sayHi are called!");

        return "hello";

    }

}

省略配置tomcat.
