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

问题

I am trying to create a simple project using Spring MVC+JPA Hibernate+maven. My web.xml is as follows

<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>

And my contact-servlet.xml as follows

Is it the problem with dependencies?

回答1:

You seem to be missing spring beans artifacts in your references. add the following to pom dependencies:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>${spring-version-for-your-project}</version>
</dependency>

回答2:

This error also occurs if you have a conflict of versions. For instance you might use spring-context in version 3.2.3.RELEASE which depends on spring-beans 3.2.3.RELEASE and in the same program use spring-batch 2.2.2.RELEASE which depends on spring-beans 3.2.0.RELEASE (note the difference in version numbers.) In that case you will have to analyze dependencies (using, for instance, Eclipses pom editor) and exclude the offending versions. In my case that would mean adding:

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