?依賴傳遞

只添加了一個struts2-core依賴，發現項目中出現了很多jar，這種情況 叫 依賴傳遞

依賴版本沖突的解決

1、? 第一聲明優先原則

<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>

?

?

?

2、? 路徑近者優先原則

自己添加jar包(自己明確的添加Jar包)

<dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>4.2.4.RELEASE</version></dependency>

?

?

3、? 排除原則

<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>

?

?

4、? 版本鎖定原則

<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><!-- 鎖定版本，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>
