Issue with Spring ServletRegistrationBean on official example

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>
