maven多模塊項目,適用于一些比較大的項目，通過合理的模塊拆分，實現代碼的復用，便于維護和管理。尤其是一些開源框架，也是采用多模塊的方式，提供插件集成，用戶可以根據需要配置指定的模塊。
項目結構如下：

test-hd-parent (父級) ---pom.xml ---test-hd-api (第三方接口層) ----pom.xml ---test-hd-foundation (基礎工具層) ----pom.xml ---test-hd-resource (資源層) ----pom.xml ---test-hd-service (邏輯業務層) ----pom.xml ---test-hd-modules (web層) ----pom.xml ---test-hd-www (web模塊1) ----pom.xml ---test-hd-admin (web模塊2) ----pom.xml |
創建一個父maven工程
新建一個maven項目，選擇存儲位置，并選擇創建一個簡單的maven工程
輸入group id、artifact id、packaging，packaging選擇pom包
生成父工程，pom.xml如下
刪除工程中的src 目錄
創建子模塊
右擊父工程名---》new---》project，然后選擇新建一個maven module工程
設置子工程名以及父工程，再設置快速創建模式
得到子工程（test-hd-api，第三方接口層），設置編譯的jdk
同理設置，子模塊：test-hd-foundation(基礎工具層)、test-hd-resource(資源層) 、test-hd-service(邏輯業務層)
新建test-hd-modules (web層)，選擇創建一個a simple project，輸入group id、artifact id、packaging，packaging選擇pom包
創建web子模塊
web子模塊在建在test-hd-modules (web層)里面，右擊test-hd-modules 工程名---》new---》project，然后選擇新建一個maven module工程，設置子工程名以及父工程，選擇新建web項目
配置maven web項目，參照：【maven】eclipse 使用maven創建java web項目
同理可以配置其他的web子模塊 test-hd-admin(web模塊2)
配置個模塊的依賴
在parent項目pom.xml中建立依賴管理（dependencymanagement）

最后使用maven-update整個工程，右擊父工程名--》maven--》update project
打包和發布
打包，右擊父工程名 test-hd-parent---->run as--->maven install
打包web子工程，右擊工程名test-hd-www--->run as ---> maven build...---> goals: clean package--->run
右擊工程名test-hd-www，進行刷新，找到war包，放到tomcat的webapps中，啟動tomcat，即可訪問工程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
以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持服務器之家。
