jar包冲突解决方案

1. 声明优先原则

<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. 路径近者优先原则

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

3. 排除原则

<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. 版本锁定原则

<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>
