Issue with Spring ServletRegistrationBean on official example - spring

Question

There are the following lines in the example of Spring-ws spring guide
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
ServletRegistrationBean bean = new ServletRegistrationBean();
return new ServletRegistrationBean(servlet, "/ws/*");
I get the following error
The constructor ServletRegistrationBean(MessageDispatcherServlet, String) is undefined
How can I fix this error?. What version of Spring boot I have to use?
****EDITED
This is the pom.xml. I think it's the same than the guide. I work with Eclipse.

Java class
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Configuration;
import org.springframework.ws.config.annotation.EnableWs;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.transport.http.MessageDispatcherServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
#EnableWs
#Configuration
public class WebServiceConfig extends WsConfigurerAdapter{
public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
MessageDispatcherServlet servlet = new MessageDispatcherServlet();
servlet.setApplicationContext(applicationContext);
servlet.setTransformWsdlLocations(true);
ServletRegistrationBean bean = new ServletRegistrationBean();
return new ServletRegistrationBean(servlet, "/ws/*");
}
Do I have to add dependencies to the pom.xml. What is the dependency wher is ServletRegistrationBean(servlet, "/ws/*");

Answer 1

The MetricsServlet needs to implement javax.servlet.Servlet dependency. You need to have this class in your project/classpath. To do this, declare this maven dependency:
<!-- https://mvnrepository.com/artifact/javax.servlet/servlet-api -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
