IDEA基于Maven搭建多模块聚合工程

一.工程目录

下面是搭建之后的目录

 

先看一下目录关系

taotao-parent（父工程管理jar包的版本）

  |--taotao-common（把通用的工具类打包）

  |--taotao-manager（继承父工程）

      |-taotao-manager-pojo

      |-taotao-manager-dao

      |-taotao-manager-service

      |-taotao-manager-web（war包）

taotao-parent 为项目的父工程，用来管理jar包及版本

taotao-common为通用工程，继承父工程，就是把通用的工具类打包

taotao-manager为开发工程，同样继承父工程

其中，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service和taotao-manager-web均为开发工程的一个子模块，依赖于开发工程taotao-manager

前3个子模块打成jar包，taotao-manager-web打成war包

二.创建工程
1.先创建一个空工程，步骤如下：
File——>new——>project

选择Empty——>next

填写工程名称和位置，点击finnish，完成了空工程的创建

2.创建父工程 taotao-parent，步骤如下：

File——>New——>Module

点maven，勾选archetype，选quickstart这项，然后Next下一步

填写GroupId，一般为组织名称；填写ArtifactId，为项目名称

选择本地maven目录及maven配置文件

填写项目名称及位置，点Finish，父工程创建完成

等待生成pom文件，修改打包方式为pom，pom文件为：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

          <version>2.2</version>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
</project>

3.创建通用工程taotao-common

File——>New——>Module

点maven后直接next下一步

继承taotao-parent,填写ArtifactId,然后next下一步

填写通用模块名称，点finish，通用模块创建完成

开发模块taotao-manager与通用模块创建方式一致

taotao-common的pom.xml

4.创建开发模块下的子模块，分两类介绍，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service创建方式一样，taotao-manager-web的创建有点差别

1）以taotao-manager-pojo为例

File——>new——>module

选maven——>勾选archetype——>选quickstart这项——>点next

继承taotao-manager，填写ArtifactId

这里注意改写路径，点finish，一个子模块创建完成

taotao-manager-pojo的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>taotao-manager</artifactId>
        <groupId>com.slx</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    </properties>
 
</project>

taotao-manager-dao的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

taotao-manager-service的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <artifactId>spring-context-support</artifactId>
        </dependency>
    </dependencies>
</project>

2）taotao-manager-web创建

同样File——>New——>Module

只不过这里选择webapp这项（唯一不同的地方，其他地方类似），点next下一步

 同样继承taotao-manager

同样需要改写路径，点击finish，taotao-manager-web子模块创建完成

taotao-manager-web的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <parent>
        <artifactId>taotao-manager</artifactId>
        <groupId>com.slx</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>taotao-manager-web</artifactId>
    <packaging>war</packaging>
    <name>taotao-manager-web Maven Webapp</name>
    <url>http://maven.apache.org</url>
    <!-- 添加依赖 -->

            <version>1.0-SNAPSHOT</version>
        </dependency>
        <!-- JSP相关 -->

            <groupId>jstl</groupId>
            <artifactId>jstl</artifactId>

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>

        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jsp-api</artifactId>
            <scope>provided</scope>
        </dependency>
        <!-- 文件上传组件 -->
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
        </dependency>
    </dependencies>
    <build>
        <finalName>taotao-manger-web</finalName>
    </build>
</project>

5.接下来运行工程使用：tomcat7:run

右上角Edit Configurations

选maven

需要把taotao-parent等需要安装的都安装到本地仓库。

最后运行，如下图所示，就说明跑通了！

 

总结：

之前看别人的博客，有选择portlet项，自己弄死活跑不通。

taotao-parent,taotao-manager-pojo,taotao-manager-dao,taotao-manager-service选择quickstart那项；

taotao-common，taotao-manager啥都不选；

taotao-manager-web选择webapp那项。

还要注意打包方式，jar，pom，war
