java.lang.NoClassDefFoundError：org / springframework / beans / factory / NoUniqueBeanDefinitionException

Spring MVC + JPA Hibernate + mavenを使用して、簡単なプロジェクトを作成しようとしています。私のweb.xmlは次のとおりです

<servlet>
    <servlet-name>ContactManager</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value></param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/contact-servlet.xml</param-value>
</context-param>

そして、次のように私のcontact-servlet.xml

依存関係の問題ですか？

参照にSpring Beanアーティファクトが欠落しているようです。以下をpom依存関係に追加します。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>3.2.2.RELEASE</version>
</dependency>

このエラーは、バージョンの競合がある場合にも発生します。たとえば、spring-beans 3.2.3.RELEASEに依存するバージョン3.2.3.RELEASEでspring-contextを使用し、同じプログラムでspring-beans 3.2.0に依存するspring-batch 2.2.2.RELEASEを使用できます。リリース（バージョン番号の違いに注意してください。）その場合は、依存関係を分析し（たとえば、Eclipse pomエディターを使用）、問題のあるバージョンを除外する必要があります。私の場合、追加することを意味します：

<dependency>
    <groupId>org.springframework.batch</groupId>
    <artifactId>spring-batch-core</artifactId>
    <version>2.2.2.RELEASE</version>
    <exclusions>
        <exclusion>
