打开 IDEA 工具，通过 File -> New -> Project，新建项目，或者直接在 IDEA 欢迎页面点击新建项目

“ GroupID ” 是项目组织唯一的标识，实际对应 Java 的包结构，是 main 目录里 Java 的目录结构，
“ ArtifactID ” 是项目的唯一的标识符，实际对应项目的名称，也就是项目根目录的名称，名为 ssmdemo 。
一路next 对于maven 这里不详细介绍
Pom中导入相关依赖

对于版本集中管理

</properties>
完善目录结构
通过 Maven 骨架生成的项目结构只有 main 目录及其目录下的 webapp 目录，这两个目录并不完善，缺少了 java 目录和 resource 目录，因此需要在 main 目录新建这两个目录，过程如下：
main -> New -> Directory -> 新建 Java 目录 main -> New -> Directory -> 新建 Resources 目录
之后需要右键选择 “ Mark Directory as ” ，分别将 java 目录和 resource 目录设置为 “ 源码根目录 ” 和 “ 配置文件目录 ”
image
之后在 resources 目录下新建 mappers 目录用来存放 MyBatis 的 mapper 文件，整个项目的目录结构就完成了，如下所示：
ssmdemo ——项目名称
├── src/main/java ——Java 源码根目录
├── controller ——控制层目录
├── dao ——dao层目录
├── entity ——实体层目录
├── service ——业务层目录
└── impl ——业务实现类目录
└── utiles ——工具类目录
├── src/main/resources ——配置文件根目录
└── mappers ——mapper文件目录
├── src/main/webapp ——网站 Web 资源
└── pom.xml ——pom文件
整合spring
resource 目录下创建applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>

整合mybatis
resource 目录下创建 mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<package name="com.ssm.demo.entity"/>
</typeAliases>
</configuration>
整合springmvc
resource 目录下创建 spring-mvc.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

<!-- 使用注解的包，包括子集 -->
<context:component-scan base-package="com.ssm.demo.controller"/>
<!-- 视图解析器 -->

最重要的是在web.xml中进行配置
