maven多项目配置

maven多模块项目时，子模块能够继承父模块的pom配置，如果想要子模块有选择性的继承父模块的pom依赖，可以将父模块的依赖配置放置在下面元素中

<dependencyManagement></dependencyManagement>

例如下面的例子

父模块配置：

<dependencyManagement><dependencies><!-- 打日志使用 --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.16</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.2</version></dependency></dependencies></dependencyManagement>

子模块选择性集成依赖配置：

<dependencies><!-- 打日志使用 --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></dependency></dependencies>
