我正在尝试构建一个Sping Boot 应用程序，一个能够加载Web界面并创建、检索、更新和删除实体的简单示例（例如学校的学生），某些操作仅限于某些用户（因此我使用Spring Security）。它工作得很好，但在Checkstyle和PMD建议进行一些更改后，它不再运行，而不是抛出以下堆栈跟踪：

这些变化是尽可能使参数和变量成为final，这通常不会导致这种情况。在堆栈跟踪中引用的唯一类是main类和Spring Security配置类：

SpringSecConfig.java

    this.provider = provider;
  }

  /**

  @Bean("daoAuthenticationProvider")
  public AuthenticationProvider daoAuthenticationProvider(final UserDetailsService service) {
    final DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
    provider.setPasswordEncoder(new BCryptPasswordEncoder());
    provider.setUserDetailsService(service);
    return provider;
  }

  /**

  @Autowired

有一个相关但未回答的问题here。
我知道在org.springframework.security.authentication.ProviderManager.checkState（）中检查的提供程序列表包含null值，这就是导致问题的原因。但我不知道为什么它包含null值。有什么想法吗？提前感谢。

我认为在调用configureAuthManager之前，您的AuthenticationProvider尚未准备好，请尝试使用（未测试）

@Autowired
  public void configureAuthManager(final AuthenticationManagerBuilder authMB, @Qualifier("daoAuthenticationProvider") AuthenticationProvider provider) {
    authMB.authenticationProvider(provider);
  }

在spring 3.0和spring security 6.0以后的版本中，如果您的httpSecurity.authenticationProvider（this.authenticationProvider）失败，并出现类似错误“提供程序列表不能包含空值”然后它指示身份验证提供程序不能在SecurityFilterChain bean之前初始化。确保您的AuthenticationProvider bean在SecurityFilterChain bean之前初始化。这可以通过以下方式完成：在SecurityFilterChain bean中使用@DependsOn（“authenticationProviderBeanName”）。
代码看起来像这样-
@Bean public authenticationProvider authenticationProvider（args.）{..}
@Bean**@DependsOn（“authenticationProvider”）**public SecurityFilterChain securityFilterChain（HttpSecurity http）throws Exception {...}
