IDEA整合Spring+Springmvc+mybatis+maven

一、创建maven项目

1. File -> New Module，进入创建项目窗口
   
   
2. 点击Next，填写GroupId、ArtifactId和Version
   
   
3. 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》
   
   
4. NEXT，填写项目名称
   
   
5. FINISH，完整结构图如下
   
   

注意事项：

1. 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

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"  
3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
4.          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee  
5.                       http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"  
6.          version="3.1"  
7.          metadata-complete="true">  
8. </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

1. pom.xml
   
   [html]  view plain  copy

三、运行

1. 创建generator
   Project Structure - +号 - maven，设置如下：
   
   
   
2. 创建tomcat容器

Project Structure - tomcat - local，设置如下：
 

运行结果：
