IDEA构建SSH项目（hibernate自动生成+jetty的使用）

1 创建Maven项目

• GroupId和ArtifactId被统称为“坐标”，是为了保证项目唯一性而提出的，如果你要把你项目弄到maven本地仓库去，你想要找到你的项目就必须根据这两个id去查找。
• GroupId=域+公司名称。域又分为org、com、cn等，其中org为非营利组织，com为商业组织。

apache公司的tomcat项目：这个项目的GroupId是org.apache，它的域是org（因为tomcat是非营利项目），公司名称是apache，ArtifactId是tomcat。

• 我一般会将GroupId设置为cn.ftx，cn表示域为中国，ftx是我个人姓名缩写，ArtifactId设置为testProject，表示这个项目的名称是testProject。
• 依照这个设置，在创建Maven工程后，新建包的时候，包结构最好是cn.ftx.testProject打头的，如果有个StudentDao，它的全路径就是cn.ftx.testProject.dao.StudentDao

2 修改目录结构

默认生成的目录结构

标准的Maven项目结构

java目录需mark didectory as source root，resources目录需mark directory as resources root

Java源代码结构

配置文件

3 在pom.xml中添加依赖
