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

<!DOCTYPE web-app PUBLIC

<web-app version="2.4"

         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

3.springmvc-config.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: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-2.0.xsd
                           http://www.springframework.org/schema/context
                           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.
