在启动SpringBoot应用程序时，我不断遇到以下错误。
它与我的SpringWebSecurityConfig文件有关吗？下面是文件内容。
@Configuration
public class SpringWebSecurityConfig extends WebSecurityConfigurerAdapter {
private AuthenticationProvider authenticationProvider;
@Autowired
@Qualifier("daoAuthenticationProvider")
public void setAuthenticationProvider(AuthenticationProvider authenticationProvider) {
this.authenticationProvider = authenticationProvider;
}
@Bean
public PasswordEncoder passwordEncoder() {
PasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
return passwordEncoder;
}
@Bean("daoAuthenticationProvider")
public AuthenticationProvider daoAuthenticationProvider(UserDetailsService userDetailsService) {
DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
provider.setPasswordEncoder(passwordEncoder());
provider.setUserDetailsService(userDetailsService);
return provider;
}
@Autowired
public void configureAuthManager(AuthenticationManagerBuilder authenticationManagerBuilder) {
authenticationManagerBuilder.authenticationProvider(authenticationProvider);
}
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity.authorizeRequests()
.antMatchers("/").permitAll()
/*.antMatchers("/","/products", "/product/show/*", "/console/*", "/h2-console/**")
.permitAll().anyRequest().authenticated()*/
.and()
.formLogin().loginPage("/login")

我确定是 @Bean（“ daoAuthenticationProvider”）的原因。似乎此Bean在服务器启动时不可用，或者在依赖它之后被加载。我尝试使用@DependsOn批注，但这给了循环依赖问题。
下面是从发生此异常的地方返回的Spring jar。 org.springframework.security.authentication.ProviderManager＃checkState
private void checkState() {
if (parent == null && providers.isEmpty()) {
throw new IllegalArgumentException(
"A parent AuthenticationManager or a list "
+ "of AuthenticationProviders is required");
} else if (providers.contains(null)) {
throw new IllegalArgumentException(
"providers list cannot contain null values");
}
}
请指导我，因为此问题间歇性地导致服务器启动失败。
