Spring安全 WebSecurity配置器适配器： 身份验证管理器构建器 - 覆盖配置方法或自动连线全局用户详细信息？

Question

亲爱的社区：我写这篇文章是为了询问我必须如何配置身份验证管理器生成器。

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
  @Autowired
  private UserDetailsService secUserDetailsService;

  @Autowired
  private PasswordEncoder secPasswordEncoder;

  . . .

  @Bean
  @Override
  public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
  }

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
      auth.authenticationProvider(authenticationProvider());
  }

  @Autowired
  public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(secUserDetailsService).passwordEncoder(secPasswordEncoder);
  }

  @Bean
  public DaoAuthenticationProvider authenticationProvider() {
    DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
    authenticationProvider.setUserDetailsService(secUserDetailsService);
    authenticationProvider.setPasswordEncoder(secPasswordEncoder);
    return authenticationProvider;
  }
}

我应该遵循哪个实现

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
      auth.authenticationProvider(authenticationProvider());
  }

和

  @Autowired
  public void globalUserDetails(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(secUserDetailsService).passwordEncoder(secPasswordEncoder);
  }

此外，我发现如果我注释整个“@Override protected void configure（AuthenticationManagerBuilder auth）”方法，我的应用程序运行良好，但当我注释@Autowired public void globalUserDetails（AutheenticationManagerBuilder auth）时，发生了以下错误：

o.s.s.o.p.endpoint.TokenEndpoint.handleException:169 - Handling error: IllegalStateException, UserDetailsService is required.
java.lang.IllegalStateException: UserDetailsService is required.

    at org.springframework.security.authentication.ProviderManager.authenticate(ProviderManager.java:175)
...

我应该使用哪种方法？此外，（这是我最关心的问题）如果我同时使用两种方法，会有任何性能问题吗？
