使用maven创建多模块web项目

使用maven创建多模块web项目

?

1.?模块说明
?wudemo-common（通用工具包）
?wudemo-dal（数据库访问层）
?wudemo-model（实体POJO）
?wudemo-core（业务核心）
?wudemo-web（web）
?
2.?进入wudemo目录，maven命令新建各个子模块
?

1. mvn?archetype:create?-DgroupId=net.welken?-DartifactId=wudemo-common?-DpackageName=net.welken.wudemo.common????
2. mvn?archetype:create?-DgroupId=net.welken?-DartifactId=wudemo-core?-DpackageName=net.welken.wudemo.core????
3. mvn?archetype:create?-DgroupId=net.welken?-DartifactId=wudemo-model?-DpackageName=net.welken.wudemo.model????
4. mvn?archetype:create?-DgroupId=net.welken?-DartifactId=wudemo-dal?-DpackageName=net.welken.wudemo.dal?????
5. mvn?archetype:create?-DgroupId=net.welken?-DartifactId=wudemo-web?-DpackageName=net.welken.wudemo.web?-DarchetypeArtifactId=maven-archetype-webapp??

?

3.?在wudemo根目录下新建一个 pom.xml 配置文件
总pom.xml文件中，以下节点需注意：

1. <groupId>net.welken</groupId>??<artifactId>wudemo-parent</artifactId>??
2. <packaging>pom</packaging>??<name>wudemo?Parent?Project</name>??
3. <version>1.0-SNAPSHOT</version>????
4. <modules>??????<module>wudemo-common</module>??
5. ????<module>wudemo-model</module>??????<module>wudemo-core</module>??
6. ????<module>wudemo-dal</module>??????<module>wudemo-web</module>??
7. </modules>??

?
?
4.?各个子pom.xml文件，添加parent节点

1. <parent>???????<artifactId>wudemo-parent</artifactId>???
2. ????<groupId>net.welken</groupId>???????<version>1.0-SNAPSHOT</version>???
3. </parent>??

5.?各个子pom.xml文件，添加依赖管理dependencies节点

1. <dependencies>??????<dependency>??
2. ????????<groupId>junit</groupId>??????????<artifactId>junit</artifactId>??
3. ????????<version>3.8.1</version>??????????<scope>test</scope>??
4. ????</dependency>???????
5. ????<dependency>??????????<groupId>net.welken</groupId>??
6. ????????<artifactId>wudemo-common</artifactId>??????</dependency>??
7. ????<dependency>??????????<groupId>net.welken</groupId>??
8. ????????<artifactId>wudemo-dal</artifactId>??????</dependency>??
9. ????<dependency>??????????<groupId>net.welken</groupId>??
10. ????????<artifactId>wudemo-core</artifactId>??????</dependency>??
11. ????<dependency>??????????<groupId>net.welken</groupId>??
12. ????????<artifactId>wudemo-model</artifactId>??????</dependency>??
13. </dependencies>?
