Spring Security basic auth for REST Api single login needed? - spring

Question

I am using Spring Security basic auth for my REST API.
Initially I get unauthorized HTTP response status for unauthenticated secured routes.
If I provide the right credentials, I get a Ok HTTP response status, but after a single successful login, I can access all the secured routes without providing user credentials.
Here are my questions:
Is it the correct behaviour for basic authentication?
Why it happens?
My security config:
#Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserService userService;
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
#Bean
public DaoAuthenticationProvider authenticationProvider() {
DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
authenticationProvider.setUserDetailsService(userService);
authenticationProvider.setPasswordEncoder(passwordEncoder());
return authenticationProvider;
}
#Override
protected void configure(HttpSecurity http) throws Exception {
//J-
http.csrf().disable()
.authorizeRequests()
.antMatchers("/save")
.permitAll()
.and()
.authorizeRequests()
.antMatchers("/h2-console/**")
.permitAll()
.anyRequest()
.authenticated()
.and()
.httpBasic();
//J+
//adding support for h2 console, otherwise crashes
http.headers().frameOptions().disable();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) {
auth.authenticationProvider(authenticationProvider());
}
}
and here is the UserDetailsService's loadByUsername() method:
#Override
public UserDetails loadUserByUsername(String username) {
User user = userRepository.findByUsername(username);
if (user == null) {
throw new UserNotFoundException(username);
} else if (UserStatus.Deactivated.equals(user.getStatus())) {
throw new UserDeactivatedException(username);
}
return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(), Collections.singleton(new SimpleGrantedAuthority("USER")));
}

Refer mentioned link. For Restful API’s use stateless session policy
