原本地址：springMVC干货系列：从零搭建springMVC+mybatis（一）：maven WEB项目的搭建
博客地址：tengj.top/
前言
今天手把手来教大家如何搭建基于Maven的SpringMVC WEB项目。
正文
开发环境介绍
IDE: MyEclipse 2014
jdk: 1.7
maven：apache-maven-3.1.1
好了，基本环境只要上面这些就行，maven不需要安装，只要有解压包就行。MyEclipse 2014有自带的插件，我们只要指定下路径就行。
MyEclipse 2014中Maven的配置
打开myeclipse中的 Window=>Preferences=>Myeclipse=>Maven4Myeclipse
配置jdk，这里我们选择1.7
配置好maven路径，也就是你之前存放maven解压包的路径
指定User Settings,对应settings.xml以及本地仓库地址，我这边是建在盘，路径为E:\m2\repository。
创建WEB项目
新建一个web项目
配置项目基本信息，项目名，java EE,java版本，其中记得要勾上Add maven support，这样才会生成带有maven的工程。
创建成功后出正确的项目结构应该是这样
配置需要的安装包
下面列出目前需要用到包，直接在pom.xl里面添加就行

xml配置，注意里面配置springMvc需要用到的DispatcherServlet，指向的地址是classpath:spring/applicationContext.xml，当然此时还没创建这个applicationCVontext.xml,下一个步骤来创建。

后期会用的的配置很多，所以我一般会根据不同用途创建不同别名的spring配置文件，然后用applicationContext.xml统一起来。
这里我创建了 applicationContext.xml以及applicationContext-mvc.xml
applicationContext.xml配置：
xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<import resource="classpath:spring/applicationContext-mvc.xml" />
beans>复制代码applicationContext-mvc.xml配置：
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc

default-lazy-init="true">
<context:component-scan base-package="com.tengj.demo"/>
<mvc:resources location="/WEB-INF/pages/" mapping="/pages/**"/>

bean>
mvc:message-converters>
mvc:annotation-driven>
beans>复制代码其中一些重要的配置下篇文章详细的说明
context:component-scan 用来扫描指定的路径下的包，来加载组件用的
mvc:resources 指定静态资源路径
实现一个简单的springMVC请求
配置文件配置好了，我们就来测试一下，写一个controller来实现前后台交互
在src/main/java下面创建如下格式的文件夹。这是我习惯的写法。
common用来存放公共的类
controller控制层
service层用来处理业务逻辑
dao层用来处理数据库操作
dto层用来存放mybatis根据表自动生成的实体对象
具体结构如下图：
在controller包下面创建一个类SendToBaiduController
package com.tengj.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping(value="/sendBaidu")
public class SendToBaiduController {
@RequestMapping(value="/view",method = RequestMethod.GET)
public String index(){
System.out.println("进来了");
return "index";
}
}复制代码index.jsp代码：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
My JSP 'index.jsp' starting page
跳转进来，表示springMVC流程成功！
复制代码部署到tomcat启动服务看看 输入地址是否控制台会打印“进来了”这3字，并跳转到index界面
http://localhost:8080/springmvctouchbaidu/sendBaidu/view
大家看，如图表示springMVC整体流程成功了
总结
到此，基于Maven的SpringMVC WEB项目搭建算是成功了，后续会基于这个基础添加其他的功能，比如整合数据库框架mybatis，多数据源处理，定时任务等等。下篇文章将整体上介绍springMVC的配置文件以及注解标签的使用。
一直觉得自己写的不是技术，而是情怀，一篇篇文章是自己这一路走来的痕迹。靠专业技能的成功是最具可复制性的，希望我的这条路能让你少走弯路，希望我能帮你抹去知识的蒙尘，希望我能帮你理清知识的脉络，希望未来技术之巅上有你也有我。
