无法在 Spring Security 配置中注入依赖项

Question

我有一个使用 Spring Security 的 spring 项目。我想将依赖项注入到我的 WebSecurityConfigurerAdapter 扩展类中，但似乎没有注入依赖项。我的控制器也使用依赖注入，它确实在那里工作。

我的 SecSecurity 课程：

@Configuration
@Component
@EnableWebSecurity
public class SecSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    UserPrincipalDetailsService userPrincipalDetailsService;
    LogoutSuccessHandler handler = new LogoutSuccess();



    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
       auth.authenticationProvider(authenticationProvider());


    }


    @Override
    protected void configure(final HttpSecurity http) throws Exception {
              http.   logout().and().
                      httpBasic()
                      .and()
                      .authorizeRequests()
                      .antMatchers( "/", "/home", "/user", "/vestigingen", "/available", "/logout").permitAll()
                      .anyRequest().authenticated()
                      .and().logout().logoutSuccessHandler(handler).deleteCookies("JSESSIONID").invalidateHttpSession(false).permitAll()
                      .and().csrf()
                      .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());


    }
    @Bean
    public UserDetailsService userDetailsService() {
        return new UserPrincipalDetailsService();
    }



    DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());
        daoAuthenticationProvider.setUserDetailsService(this.userPrincipalDetailsService);


        return daoAuthenticationProvider;
    }

}

它找不到 userPrincipalDetailsS​​ervice 类的 bean。

UserPrincipalDetailService 类：

@Component
public class UserPrincipalDetailsService implements UserDetailsService {
    private UserRepositorySQL userRepository = new UserRepositorySQL();

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
        UserEntity user = userRepository.findUserByUsername(s);

        UserPrincipal userPrincipal = new UserPrincipal(user);

        return userPrincipal;
    }
}

澄清一下：我无法在我的 SecSecurityConfig 类中注入任何依赖项，尽管我已经尝试以多种不同的方式对其进行注释。

在 UserPrincipalDetailsS​​ervice 类中定义 bean 名称 @Component("userPrincipalDetailsS​​ervice")。

@Component("userPrincipalDetailsService")
public class UserPrincipalDetailsService implements UserDetailsService {
    private UserRepositorySQL userRepository = new UserRepositorySQL();

    @Override
    public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
        UserEntity user = userRepository.findUserByUsername(s);

        UserPrincipal userPrincipal = new UserPrincipal(user);

        return userPrincipal;
    }
}
