**SpringMVC01\_基本环境搭建**

--------------------

*  创建maven工程,选择模板：**org.apache.maven.archetypes maven-archetype-webapp**
 *  pom文件中去掉junit，引入springmvc的依赖

      </build
    </project>

*  在src/main下创建java目录，设置为**Sources Root**，创建**resources**目录，设置为**Resources Root**
 *  修改web.xml

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    <web-app>
      <display-name>Archetype Created Web Application</display-name>
      
      <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springmvc.xml</param-value>
        </init-param>
      </servlet>
      
      <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    </web-app>

*  在resources下创建springmvc.xml配置文件

<?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-4.3.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-4.3.xsd">
    
        <context:component-scan base-package="com.blu"></context:component-scan>
    
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/" ></property>
            <property name="suffix" value=".jsp"></property>
        </bean>
    
    </beans>

*  创建HelloHandler

package com.blu.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HelloHandler { 
    
        @RequestMapping("/index")
        public String index(){ 
            System.out.println("执行了index...");
            return "index";
        }
    }

加入Tomcat中运行，浏览器访问：http://localhost:8080/index
