自定义Spring UserDetailsS​​ervice不被调用

我试图为当前登录的用户添加一些自定义数据,所以我发现可以实现自己的UserDetailsS​​ervice并将其插入Spring中,但从未调用过,我总是将Principal用作用户名字符串。 / p>

我有UserDetailsS​​ervice的实现:

game view

我对UserDetails的实现:

@Service
public class UserDetailServiceImpl implements UserDetailsService {

  @Override
  public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
    ...
  }
}

并尝试通过多种方式在config(SecurityConfiguration)中进行设置:

import org.springframework.security.core.userdetails.User;

public class LoggedInUser extends User {
...
}

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
      @Autowired
      private CustomAuthenticationProvider customAuthProvider;
      @Autowired
      private UserDetailsService userDetailServiceImpl;
      @Override
      protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(customAuthProvider);
        auth.userDetailsService(userDetailServiceImpl).passwordEncoder(passwordService.getPasswordEncoder());
      }
...
}

@Autowired
  protected void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(customAuthProvider);
    auth.userDetailsService(userDetailServiceImpl).passwordEncoder(passwordService.getPasswordEncoder());
  }

无效,...我尝试过多种方式检索用户信息:

  1. 在具有@AuthenticationPrincipal的控制器中,我得到空
  2. 在使用中(我收到无效的转换错误):

    身份验证身份验证= SecurityContextHolder.getContext()。getAuthentication(); (LoggedInUser)authentication.getPrincipal()

有人知道为什么它不起作用吗?我的impl类是否默认被其他地方覆盖?我试图查看日志(logging.level.org.springframework.security = TRACE),但没有运气:/ 我可以登录,效果很好,只是主体数据始终只是用户名String,而不是我的课程。

ILya Cyclone的评论是找出问题所在的关键,再次检查CustomAuthenticationProvider后,我注意到在返回数据时,您可以指定Principal,而不仅仅是用户名,您可以在其中添加自定义UserDetails,由于未调用该自定义UserDetailsService,因此我以为总是调用该自定义错误。

因此,最终足以将自定义AuthenticationProvider与自定义UserDetails

@Service
public class CustomAuthenticationProvider implements AuthenticationProvider {

  @Autowired
  private UserService userService;

  @Autowired
  private PasswordService passwordService;

  @Override
  public Authentication authenticate(Authentication auth) throws AuthenticationException {
    String username = auth.getName();
    String password = auth.getCredentials().toString();

    User user = userService.getUserWithPermissionsByName(username);
    if (user == null) {
      throw new BadCredentialsException("invalid_username_or_pass");
    }

    if (!passwordService.passwordsMatch(password, user.getPassword())) {
      throw new BadCredentialsException("invalid_username_or_pass");
    }

    String[] permissions = user.getPermissions().stream().map((p) -> p.getName()).toArray(String[]::new);
    List<GrantedAuthority> grantedAuths = AuthorityUtils.createAuthorityList(permissions);
    return new UsernamePasswordAuthenticationToken(new LoggedInUser(user.getName(), user.getPassword(), true, true, true, true, grantedAuths, user.getId()),
        password, grantedAuths);
  }

  @Override
  public boolean supports(Class<?> auth) {
    return auth.equals(UsernamePasswordAuthenticationToken.class);
  }
}
