I was looking through similar questions, but did not find anything that helped:
In my spring security configuration class I configure my AuthenticationManager like this (to use a UserDetailsService implementation). I have read, that this should configure a global authentication manager to use.
@EnableWebMvc
@EnableWebSecurity
@ComponentScan
@Configuration
public class WebMvcConfig extends WebSecurityConfigurerAdapter implements WebMvcConfigurer {
// Other things...
@Autowired
@Qualifier("authenticationManager")
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}
}
My question is: How to use it in a custom controller? If I try it like this ...
@Controller
@RequestMapping(value = "/perform_login", method = RequestMethod.POST)
public class LoginController {
@Resource
private AuthenticationManager authenticationManager;
@GetMapping
public ModelAndView login(
// login logic using the authenticationManager
}
}
... then it says, that no bean of type AuthenticationManagerBuilder is available. So please help me out: Where is my misunderstanding? How can I actually use the AuthenticationManager?
