Maven多模块项目

  Maven多模块项目,适用于一些比较大的项目,通过合理的模块拆分,实现代码的复用,便于维护和管理。尤其是一些开源框架,也是采用多模块的方式,提供插件集成,用户可以根据需要配置指定的模块。

  项目结构如下:

      test-hd-parent   (父级)
             ---pom.xml
             ---test-hd-api          (第三方接口层)
                    ----pom.xml    
           ---test-hd-foundation     (基础工具层)
                    ----pom.xml
             ---test-hd-resource     (资源层) 
                    ----pom.xml
             ---test-hd-service       (逻辑业务层)
                    ----pom.xml
           ---test-hd-modules     (web层)
                    ----pom.xml
                ---test-hd-www         (web模块1)
                            ----pom.xml
                ---test-hd-admin        (web模块2)
                            ----pom.xml     

创建一个父maven工程

  •   新建一个maven项目,选择存储位置,并选择创建一个简单的maven工程

    

  •   输入Group Id、Artifact Id、Packaging,packaging选择pom包

    

  •   生成父工程,pom.xml如下

    

  •   删除工程中的src 目录

    

创建子模块

  •   右击父工程名---》New---》Project,然后选择新建一个maven module工程

    

  •   设置子工程名以及父工程,再设置快速创建模式

    

  •   得到子工程(test-hd-api,第三方接口层),设置编译的jdk

    

  •   同理设置,子模块:test-hd-foundation(基础工具层)、test-hd-resource(资源层) 、test-hd-service(逻辑业务层)
  •   新建test-hd-modules (web层),选择创建一个a simple project,输入Group Id、Artifact Id、Packaging,packaging选择pom包

        

创建web子模块

  •   web子模块在建在test-hd-modules (web层)里面,右击test-hd-modules 工程名---》New---》Project,然后选择新建一个maven module工程,设置子工程名以及父工程,选择新建web项目

    

    

 

配置个模块的依赖

  •   在parent项目pom.xml中建立依赖管理(dependencyManagement)

  •     最后使用maven-update整个工程,右击父工程名--》Maven--》Update Project

    

打包和发布

  •   打包,右击父工程名 test-hd-parent---->Run As--->Maven Install

   

 

  •   打包web子工程,右击工程名test-hd-www--->Run As ---> Maven Build...---> Goals: clean package--->Run

      

      

 

  •   右击工程名test-hd-www,进行刷新,找到war包,放到tomcat的webapps中,启动tomcat,即可访问工程http://localhost:8080/test-hd-www

    

  •   可以去tomcat下面webapps》test-hd-www》WEB-INF》lib中,看到引用的jar包
