父pom配置：
<packaging>pom</packaging>
在父pom中配置依赖管理和插件管理
<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">
 <modelVersion>4.0.0</modelVersion>

 <groupId>cxxcode.maven</groupId>
 <artifactId>account-parent</artifactId>
 <packaging>pom</packaging>
 <version>0.0.1</version>
 <name>Account Parent</name>
 <url>http://maven.apache.org</url>

 <properties>
  <spring-version>2.5.6</spring-version>
  <junit-version>4.7</junit-version>
  <mail-version>1.4.1</mail-version>
  <greenmail-version>1.3.1b</greenmail-version>
  <dom4j-version>1.6.1</dom4j-version>
  <surefire-version>2.5</surefire-version>
 </properties>

  依赖管理dependencyManagement
   假设不使用依赖管理。子pom会继承父pom中配置的全部依赖，子pom中仅仅需配置自己特需的依赖即可了，
   这样尽管简化了子pom的配置。可是强制性给子pom加上多余的依赖。
   
   使用依赖管理，子pom中要配置自己须要的依赖。假设这些依赖在父pom中配置了，
   子pom仅仅需指定这些依赖的groupId和artifactId
   
   
  依赖管理的导入
   将proj-A中的依赖管理导入此pom的依赖管理中
   
   <scope>import</scope>仅仅用在依赖管理配置中。且<type>pom</type>
