Java annotation based Spring security config

I try to do the Java annotation based Spring security configuration. I do this after following a tutorial and have the code as provided,

@Configuration
@EnableWebSecurity
// need to change this to the security directory
@ComponentScan("")
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private RestAuthenticationEntryPoint restAuthenticationEntryPoint;

    @Autowired
    private MySavedRequestAwareAuthenticationSuccessHandler authenticationSuccessHandler;

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {

        auth.inMemoryAuthentication()
                .withUser("temporary").password("temporary").roles("ADMIN")
                .and()
                .withUser("user").password("userPass").roles("USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .exceptionHandling()
                .authenticationEntryPoint(restAuthenticationEntryPoint)
                .and()
                .authorizeRequests()
                .antMatchers("/api/foos").authenticated()
                .and()
                .formLogin()
                .successHandler(authenticationSuccessHandler)
                .failureHandler(new SimpleUrlAuthenticationFailureHandler())
                .and()
                .logout();
    }

    @Bean
    public MySavedRequestAwareAuthenticationSuccessHandler mySuccessHandler() {
        return new MySavedRequestAwareAuthenticationSuccessHandler();
    }

    @Bean
    public SimpleUrlAuthenticationFailureHandler myFailureHandler() {
        return new SimpleUrlAuthenticationFailureHandler();
    }
}

The API base for the project I work,

public static final String API_BASE = "/*";

For example, I do the cURL request like,

curl -X GET http://localhost:8080/rest/wallet/wallets | json

I'm not sure about the .antMatchers("/api/foos").authenticated() line in the code. For example, from where the foos is coming and do I need to change it to something like .antMatchers("/foos").authenticated()?
