Why does UserDetailsService return null in Spring Boot app?
Question
A simple spring boot app has a custom UserDetailsService. The Spring Boot Controller is called by an AngularJS app, and authentication requests from the AngularJS app are made to the backend at the /user url pattern. But login requests are causing the controller logs to indicate that the controller is not finding the /user url pattern, and that the UserDetailsService is thus returning null. What specific changes need to be made to the code below in order to enable client requests for the backend /user url pattern to find the controller method and thus also correctly instantiate the custom UserDetailsService ?
The app is so simple that the controller is less than 200 lines of code.
The code for the controller is:
@SpringBootApplication
@Controller
@EnableJpaRepositories(basePackages = "demo", considerNestedRepositories = true)
public class UiApplication extends WebMvcConfigurerAdapter {
// Match everything without a suffix (so not a static resource)
@RequestMapping(value = "/{[path:[^\\.]*}")
public String redirect() {
// Forward to home page so that route is preserved.
return "forward:/";
}
@RequestMapping("/user")
@ResponseBody
public Principal user(Principal user) {
return user;
}
public static void main(String[] args) {
SpringApplication.run(UiApplication.class, args);
}
@Bean
public LocaleResolver localeResolver() {
SessionLocaleResolver slr = new SessionLocaleResolver();
slr.setDefaultLocale(Locale.US);
return slr;
}
@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
lci.setParamName("lang");
return lci;
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/login").setViewName("login");
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localeChangeInterceptor());
}

The controller method is found. The problem is this code:
if (user == null) {
return null;
}
As you clearly can see in the log messages:
Authentication request for failed: org.springframework.security.authentication.InternalAuthenticationServiceException: UserDetailsService returned null, which is an interface contract violation
Returning null is not allowed in a UserDetailsService implementation.
So check if you have an entry in your database for the admin user and remove the return null and throw a UsernameNotFoundException instead.
