Maven管理Spring

【pom.xml配置文件信息】
Project Object Model，項目對象模型。通過xml格式保存的pom.xml文件。作用類似ant的build.xml文件，功能更強大。
該文件用於管理：源代碼、配置文件、開發者的信息和角色、問題追蹤系統、組織信息、項目授權、項目的url、項目的依賴關係等等。

【Maven的pom.xml多項目以來配置】

多項目管理

maven的多項目管理也是非常強大的。一般來說，maven要求同一個工程的所有子項目都放置到同一個目錄下，每一個子目錄代表一個項目，比如

總項目/
pom.xml 總項目的pom配置文件
子項目1/
pom.xml 子項目1的pom文件
子項目2/
pom.xml 子項目2的pom文件
按照這種格式存放，就是繼承方式，所有具體子項目的pom.xml都會繼承總項目pom的內容，取值爲子項目pom內容優先。

要設置繼承方式，首先要在總項目的pom中加入如下配置

Xml代碼
<modules>
<module>simple-weather</module>
<module>simple-webapp</module>
</modules>

其次在每個子項目中加入

<parent>
<groupId>org.sonatype.mavenbook.ch06</groupId>
<artifactId>simple-parent</artifactId>
<version>1.0</version>
</parent>
即可。

當然，繼承不是唯一的配置文件共用方式，maven還支持引用方式。引用pom的方式更簡單，在依賴中加入一個type爲pom的依賴即可。

Xml代碼
<project>
<description>This is a project requiring JDBC</description>
...
<dependencies>
...
<dependency>
<groupId>org.sonatype.mavenbook</groupId>
<artifactId>persistence-deps</artifactId>
<version>1.0</version>
<type>pom</type>
</dependency>
</dependencies>
</project>

【Maven管理spring、(pom.xml)】使用tree展示原型目錄結構：

【profile】
profile可以讓我們定義一系列的配置信息，然後指定其激活條件。
這樣我們就可以定義多個profile，然後每個profile對應不同的激活條件和配置信息，從而達到不同環境使用不同配置信息的效果。
比如說，我們可以通過profile定義在jdk1.5以上使用一套配置信息，在jdk1.5以下使用另外一套配置信息；或者有時候我們可以通過操作系統的不同來使用不同的配置信息，比如windows下是一套信息，linux下又是另外一套信息，等等。
profile的定義位置：
（1）針對於特定項目的profile配置我們可以定義在該項目的pom.xml中。
（2）針對於特定用戶的profile配置，我們可以在用戶的settings.xml文件中定義profile。該文件在用戶家目錄下的“.m2”目錄下。
（3）全局的profile配置。全局的profile是定義在Maven安裝目錄下的“conf/settings.xml”文件中的。
