我'm creating a maven project and I'是一个初学者..我收到了这个错误 . 可以帮助解决这个问题是我的pom.xml和web.xml [重复]

这个问题在这里已有答案:

你混合了Spring依赖项的版本,除非你有特殊的原因,否则你永远不应该这样做 .

请参阅这篇博文,详细介绍了如何以及为什么你不应该't do this, it'的 Spring 季靴子相关但这个想法完全相同https://spring.io/blog/2016/04/13/overriding-dependency-versions-with-spring-boot

这里显示的快速示例,http://www.baeldung.com/spring-maven-bom

<dependencyManagement>

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-framework-bom</artifactId>
   <version>4.3.12.RELEASE</version>
   <type>pom</type>
   <scope>import</scope>
</dependency>

</dependencyManagement>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
</dependency>

<!-- The spring-web module provides basic web-oriented integration features 
    such as multipart file upload functionality and the initialization of the 
    IoC container using Servlet listeners and a web-oriented application context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-tx -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
</dependency>

<!-- https://mvnrepository.com/artifact/org.springframework/spring-beans -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
</dependency>
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

依赖关系通过BOM导入进行控制 . 另外,我相信你所定义的很多内容都是可传递的,例如:不应该定义 contextbeans 等 . 我会检查您的依赖关系层次结构并展平已定义的依赖关系 .
