Spring security login not showing

Question

I'm adding Spring Security on a Spring MVC app; however, when I run the application, the Spring Security default login does not show up (not even when I browse to a link which is supposed to be "secured").

Configuration class (forgive the indentation):

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConf extends WebSecurityConfigurerAdapter {

@Autowired
private UserService userDetailsService;

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
    http.authorizeRequests()
            .antMatchers("**/secured/**").authenticated()
            .anyRequest().permitAll()
            .and()
            .formLogin().permitAll();
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService).passwordEncoder(getPasswordEncoder());
}

private PasswordEncoder getPasswordEncoder() {
    return new PasswordEncoder() {

        @Override
        public boolean matches(CharSequence rawPassword, String encodedPassword) {
            return encode(rawPassword).equals(encodedPassword);
        }

        @Override
        public String encode(CharSequence rawPassword) {
            return rawPassword.toString();
        }
    };
}   }

I also tried adding a custom login, but it does not seem to find the page (which is otherwise reachable):

http.authorizeRequests()
            .antMatchers("**/secured/**").authenticated()
            .anyRequest().permitAll()
            .and()
            .formLogin().loginPage('/login').permitAll();

Summing up, I need the default Spring Security login page to be displayed first, so I can test the authentication, then I need to be able to add a new login form to be displayed instead. What should I do?

EDIT: I figured out the configuration problem which prevented the Spring login to be displayed. The following tags had to be added in the web.xml file in order to integrate Spring Security with Spring MVC. Now the login is succesfully displayed.

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
