[Spring][Actuators] Failed to process import candidates for configuration class

I am trying to implement actuators in my spring project (NOT spring boot). I added below dependency in my pom file:

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-actuator</artifactId>
        <version>1.3.5.RELEASE</version>
    </dependency>

Also added the class below:

import java.util.Collection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.autoconfigure.EndpointAutoConfiguration;
import org.springframework.boot.actuate.autoconfigure.PublicMetricsAutoConfiguration;
import org.springframework.boot.actuate.endpoint.MetricsEndpoint;
import org.springframework.boot.actuate.endpoint.mvc.EndpointHandlerMapping;
import org.springframework.boot.actuate.endpoint.mvc.EndpointMvcAdapter;
import org.springframework.boot.actuate.endpoint.mvc.MvcEndpoint;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

@Configuration
@Import({EndpointAutoConfiguration.class, PublicMetricsAutoConfiguration.class})
public class SpringBootActuatorConfigBindings {

    @Bean
    @Autowired
    public EndpointHandlerMapping endpointHandlerMapping(Collection<? extends MvcEndpoint> endpoints) {
        return new EndpointHandlerMapping(endpoints);
    }

    @Bean
    @Autowired
    public EndpointMvcAdapter metricsEndPoint(MetricsEndpoint delegate) {
        return new EndpointMvcAdapter(delegate);
    }
}

But on running i am getting below error:

[local] [] [ERROR] [2019-04-22T14:24:47,347] [ Console scanner] [work.web.context.ContextLoader] Context initialization failed org.springframework.beans.factory.BeanDefinitionStoreException: Failed to

If you check your Exception logs:

Caused by: java.lang.IllegalStateException: Failed to introspect annotated methods on class com.mycompany.ans.processor.bindings.SpringBootActuatorConfigBindings

Caused by: java.lang.NoClassDefFoundError:
  org/springframework/web/servlet/mvc/method/annotation/RequestMappingHandlerMapping
  at java.lang.ClassLoader.defineClass1(Native Method) ~[?:1.8.0_202]
...

You need to include the dependency for Spring Web mvc, from which the RequestMappingHandlerMapping class is implemented and required. This is the cause of the NoClassDefFoundError.

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
  <version>${org.springframework.version}</version>
</dependency>
