03 图书管理系统（SSM+LayUi）

创建ssm项目工程

3.1 创建maven工程

• 1、打开IDEA->file->new->project
• 2、选择Maven，勾选Create from archetype，
  选择org.apache.maven.archetypes:maven-archetype-webapp

3.2 使用自己安装的maven

• 更改Maven home directory
• 更改User settings file（maven/conf/settings.xml）
• 添加Properties{archetypeCatalog:internal}

3.3 加入maven依赖jar包

在pom.xml中导入依赖坐标

3.4 完善目录结构

• 在main文件夹下新建java和resources目录
• 分别右击选择Mark Directory as
• 点击Sources Root和Resources Root

3.5 目录进行分层

在main.java文件夹中新建目录如下

• com.gychen.controller
• com.gychen.dao
• com.gychen.po
• com.gychen.service
• com.gychen.util
