SSM001/构建maven多模块项目

一。Idea构建maven多模块项目

1。创建maven项目--创建父模块

【1】。File->New->Module...

【2】。点击next，填写：GroupId,ArtifactId和Version

注：ArtifactId即为项目名字。

【3】。点击next，添加参数archetypeCatalog=internal（不加该参数，在maven生成骨架时会非常慢）

注：

archetypeCatalog表示插件使用的archetype元数据，不加这个参数时默认为remote，local，即中央仓库archetype元数据，
由于中央仓库的archetype太多了所以导致很慢，指定internal来表示仅使用内部元数据。

【4】点击next，填写module name（模块名称）->finish

【5】。项目结构如下所示：

2。创建module子模块

【1】右击项目-》new Module..

【2】新建Module同1创建父模块。

修改点：

（1）。ArtifactId：ssm-web

（2）。Modual name：ssm-web

最终项目架构如下所示：

3。每个模块中依赖pom.xml配置

maven模块结构图：

---web-ssm

　　　　|--pom.xml(pom)

　　　　|--ssm-web

　　　　　　|--pom.xml(war)

　　　　|--ssm-service

　　　　　　|--pom.xml(jar)

　　　　|--ssm-dao

　　　　　　|--pom.xml(jar)

　　　　|--ssm-model

　　　　　　|--pom.xml(jar)

注意：括号中标识的是模块的打包（packaging类型）。父项目只能为pom，子项目根据包含内容具体考虑打jar/war包。

maven依赖传递性：

|-ssm-dao模块：负责与数据库交互，持久层。依赖于model层（ssm-model）

         ssm-dao->依赖->ssm-model

|-ssm-service模块：负责业务逻辑处理，事务控制层。调用dao传递处理结果。依赖于dao层(ssm-dao)。

                             而dao依赖于model层。所以service依赖于model层(ssm-model)

        ssm-service->依赖->ssm-dao->依赖->ssm-model

|-ssm-web模块：负责与客户端交互，控制层。主要为springmvc的controller类/struts的action类。

                         依赖于service层。依赖于dao层，依赖于model层。（依赖传递性）

        ssm-web->依赖->ssm-service->依赖->ssm-dao->依赖->ssm-model

|-ssm-model模块：独立模块，不依赖于任何其他模块

上述：除非配置了特殊的依赖scope。否则依赖均具有传递性。
