[FIXED] Spring security 401 Unauthorized on unsecured endpoint

Issue

I'm trying to configure Spring Security on a Spring Boot application as follows:

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

@Autowired
private RestAuthenticationEntryPoint unauthorizedHandler;

@Bean
public JwtAuthenticationFilter authenticationTokenFilterBean() throws Exception {
    JwtAuthenticationFilter authenticationTokenFilter = new JwtAuthenticationFilter();
    authenticationTokenFilter.setAuthenticationManager(authenticationManagerBean());
    return authenticationTokenFilter;
}

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {

    //@formatter:off
     httpSecurity
      .csrf()
        .disable()
      .exceptionHandling()
        .authenticationEntryPoint(this.unauthorizedHandler)
        .and()
      .sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
        .and()
      .authorizeRequests()
        .antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
        .antMatchers("/login", "/singup", "/subscribers").permitAll()
        .anyRequest().authenticated();

        // Custom JWT based security filter 
    httpSecurity            
        .addFilterBefore(authenticationTokenFilterBean(), UsernamePasswordAuthenticationFilter.class);   

    //@formatter:on

}
}

My unauthorizedHandler is:

public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {

private static final Logger LOGGER = LoggerFactory.getLogger(RestAuthenticationEntryPoint.class);

@Override
public void commence(HttpServletRequest request, HttpServletResponse response,
        AuthenticationException authException) throws IOException, ServletException {
    response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized");
}

}

Finally, the REST controller for /subscribers is:

@RestController
public class SubscriberRestController {

@Autowired
ISubscribersService subscribersService;

@RequestMapping(value = RequestMappingConstants.SUBSCRIBERS, method = RequestMethod.GET)
@ResponseBody
public Number subscriberCount() {

    return subscribersService.subscribersCount();
}

@RequestMapping(value = RequestMappingConstants.SUBSCRIBERS, method = RequestMethod.POST)
public String subscriberPost(@RequestBody SubscriberDocument subscriberDocument) {

    return subscribersService.subscribersInsert(subscriberDocument);
}

@RequestMapping(value = "/test", method = RequestMethod.GET)
public String test() {

    return "This is a test";
}

}

I use postman to test endpoints and when I do a POST to "localhost:8080/subscribers", I get:

I want to have opened endpoints (/subscribers) without any security control or credentials check, endpoints for singup and login and secured endpoints for authenticated users.

Thanks! :)

Solution

Spring Boot was not applying the configuration because couldn't find it. On Application.java config package was not included with @ComponentScan anotation.
