SEO user friendly url using Pretty faces and spring boot

Question

I have followed this to configure spring boot work with JSF and the configuration is ok however I need to get rid of.xhtml suffix in all my jsf using pretty faces. I have so far managed to configure PrettyFaces RewriteFilter in my spring boot and added the URLMapping in my managed bean but it doesnt seem to work am getting ' Whitelabel Error Page '. Here is my login managed bean

@Scope(value = "session")
@Component(value = "loginMgr")
@URLMapping(id = "login",
        pattern = "/login",
        viewId = "/my_context/login.xhtml")
public class LoginManager {

}

and my pretty faces configuration bean

@Bean
public FilterRegistrationBean prettyFilter() {
    System.out.println("pretty filter called");
    RewriteFilter filter=new RewriteFilter();
    FilterRegistrationBean prettyFilter = new FilterRegistrationBean(filter);
    prettyFilter.setDispatcherTypes(DispatcherType.FORWARD, DispatcherType.REQUEST,
            DispatcherType.ASYNC, DispatcherType.ERROR);
    prettyFilter.addUrlPatterns("/*");

    return prettyFilter;
}

and this is my sping boot application.properties

spring.datasource.url= jdbc:postgresql://localhost:5432/mydb
spring.datasource.username=postgres
spring.datasource.password=password
#spring.jpa.show-sql=true
spring.datasource.driver-class-name=org.postgresql.Driver
#spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
server.context-path=/my_context
spring.security.enabled=false
management.security.enabled=false
security.basic.enabled=false
spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.ImprovedNamingStrateg

I am using jsf 2.2 and primefaces 5.3 and below are the pretty faces maven dependency

<dependency>
            <groupId>org.ocpsoft.rewrite</groupId>
            <artifactId>rewrite-servlet</artifactId>
            <version>3.4.1.Final</version>
        </dependency>
        <dependency>
            <groupId>org.ocpsoft.rewrite</groupId>
            <artifactId>rewrite-integration-faces</artifactId>
            <version>3.4.1.Final</version>
        </dependency>

and this is the error am getting

If you would like to get rid of the.xhtml suffix and use MyFaces 2.3, you can simply set: org.apache.myfaces.AUTOMATIC_EXTENSIONLESS_MAPPING to true .

So you dont need PrettyFaces or Rewrite.

NOTE: it might throw a exception that #getServletRegistrations can't be called from a Listener not configured in web.xml or web-fragment.xml . In this case you need to add org.apache.myfaces.webapp.StartupServletContextListener to your web.xml or web-fragment.xml ..
