Probably you have forgot to import your product-servlet to configuration class

you could move your product-servlet.xml to 'resources' so that it is available in classpath

so your servlet mapping looks like this

<servlet>  
        <servlet-name>product</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/product-servlet.xml</param-value>
         </init-param>  
        <load-on-startup>1</load-on-startup>  
</servlet> 
<servlet-mapping>
    <servlet-name>product</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

in your config class

 @Configuration
    @EnableTransactionManagement
    @ComponentScan("com.kopylov.spring")
    @PropertySource("classpath:/com/kopylov/spring/resources/app.properties")
    @EnableJpaRepositories("com.kopylov.spring.repository")
    @ImportResource("classpath:/product-servlet.xml")
    public class DataConfig {
    //..
    }

BTW, better not to mix match xml and java configuration. As java config has become norm, you could use WebMvcConfigurerAdapter

Perfect solution worked for me :

Add commons-configuration-1.6.jar to the lib directory

    Use jdk 1.8

    1. SpringMVC-4.3.3
    2. SpringCore-4.3.3
    3. javax.servlet-api-3.0.1
    4. spring-data-jpa:1.10.4
    5. hibernate-entitymanager:4.2.5.Final
    6. hibernate-core:4.2.5.Final
    7. Simple Logging Facade for Java:1.6.1

    I encountered with such error

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotatedElementUtils.hasAnnotation

    My question:
    Why error encoured and how fix it?
