IDEA整合Spring+Springmvc+mybatis+maven

一、创建maven项目

File -> New Module，进入创建项目窗口



点击Next，填写GroupId、ArtifactId和Version



接着下一步，这里需要注在Properties中添加一个参数 archetypeCatalog=internal，不加这个参数，在maven生成骨架的时候将会非常慢，有时候直接卡住。来自网上的解释：

archetypeCatalog表示插件使用的archetype元数据，不加这个参数时默认为remote，local，即中央仓库archetype元数据，由于中央

仓库的archetype太多了所以导致很慢，指定internal来表示仅使用内部元数据。

《摘自：http://blog.csdn.net/gallenzhang/article/details/51932152》



NEXT，填写项目名称



FINISH，完整结构图如下



注意事项：

刚才创建的MAVEN项目，web.xml默认是servlet2.3版本，版本较低，需要手动改为servlet3.0以上版本，如图：



修改为下面代码即可

[html] view
plain copy

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

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1"

metadata-complete="true">

</web-app>

2. src/main下面目录不全，缺少test,java等目录，也需要手动完善

首先打开Project Structure - Modules，修改如下：

二、配置文件
