一、第一声明优先原则
示例:
<dependencies><!-- spring-beans-4.2.4 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.2.4.RELEASE</version> </dependency> <!-- spring-beans-3.0.5 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.24</version> </dependency>
二、路径近者优先原则
示例:
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.2.4.RELEASE</version></dependency>
三、排除原则
示例:
<dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.24</version> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </exclusion> </exclusions></dependency>
四、版本锁定原则
示例:
<properties><spring.version>4.2.4.RELEASE</spring.version><hibernate.version>5.0.7.Final</hibernate.version><struts.version>2.3.24</struts.version></properties><!-- 锁定版本,struts2-2.3.24、spring4.2.4、hibernate5.0.7 --><dependencyManagement><dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency> </dependencies></dependencyManagement>
