Maven多模塊項(xiàng)目搭建+SSM框架整合（一、多模塊搭建）

標(biāo)簽：

Java MySQL WebApp

项目使用IDEA进行构建，源码将会提交到GitHub上，使用Eclipse的用户也可以轻松导入。

在此我们将项目划分为4块，分别为model、dao、service和controller。

一、创建父模块

打开IDEA创建项目

点击Maven直接选择Next

补全GroupId与ArtifactId

填写项目名称与存放本地地址

此时项目结构如图

二、创建model子模块

如图

在此因为是普通的子模块所以我们还是直接next

接着填写ArtifactId

填写Module name接着finish

最终项目结构如下图所示

创建dao、service这两个子模块与model一样

最终项目结构如图

三、创建子模块controller

还是先创建Module

然后选择webapp

接着填写ArtifactId

接下来是Maven的配置，可以参考Maven 环境变量设置---------IDEA配置maven

点击finish多模块的框架就基本上搭建好了

如图所示

四、每个模块中依赖的配置

配置mytest-model中的pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
