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

        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <spring.version>4.2.4.RELEASE</spring.version>

        <mybatis-spring.version>1.2.2</mybatis-spring.version>
        <maven.test.skip>true</maven.test.skip>
      </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 ”

![1708247-20190610143256141-1642770074.png][]

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

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

最重要的是在web.xml中进行配置
