Spring Security basic auth always getting 401 - spring-boot

Question

I learning Spring, and I integrated Spring security into my current APIs. To keep things simple, I am starting with Basic Auth.
However, the issue that I am facing is that, if I don't provide the credentials, I get the standard 401 along with a JSON response:
{
"timestamp": "2018-07-07T18:40:00.752+0000",
"status": 401,
"error": "Unauthorized",
"message": "Unauthorized",
"path": "/courses"
}
But if I do pass correct credentials, I get 401, but without any response body.
Here's my WebSecurityConfiguration:
#Configuration
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
DetailsService detailsService;
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(detailsService)
.passwordEncoder(User.encoder);
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic()
.and()
.csrf().disable();
}
}
Here's my DetailsService:
#Component
public class DetailsService implements UserDetailsService {
#Autowired
private UserRepository userRepository;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userRepository.findByEmail(username);
if (user == null) {
throw new UsernameNotFoundException("User with email " + username + " was not found");
}
return new org.springframework.security.core.userdetails.User(
user.getEmail(),
user.getPassword(),
AuthorityUtils.createAuthorityList(user.getRoles())
);
}
}
I should point this out that I am looking up user by email instead of username.
Here's my user entity:
#Entity
#Table(name = "users")
public class User extends BaseEntity {
public static final PasswordEncoder encoder = new BCryptPasswordEncoder();
#Column(name = "first_name")
private String firstName;
#JoinColumn(name = "last_name")
private String lastName;
private String email;
#JsonIgnore
private String password;
#JsonIgnore
private String[] roles;
public User(String email, String firstName, String lastName, String password,
String[] roles) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
setPassword(password);
this.roles = roles;
}
// getters and setters
}

Answer 1

First: check that user.getRoles() is not throwing a LazyInitializationException
Second: if hash has been generated online, BCryptPasswordEncoder might not work
