我从我的自定义AuthenticationProviders中删除了@Component注解，我在SecurityConfiguration类中为每个自定义AuthenticationProvider创建了@Beans，我直接调用了它们的构造函数，而不是使用springs DI。然后在我的AthenticationManager Bean中使用它们，我返回了一个ProviderManager。
说明代码片段：

@Configuration
class ProdSecurityConfiguration {

    @Bean
    fun credentialsAuthProvider(): AuthenticationProvider {
        return CredentialsAuthProvider()
    }

    @Bean
    fun credentialsAuthProvider2(): AuthenticationProvider {
        return CredentialsAuthProvider2()
    }

    @Bean
    fun authenticationManager(): AuthenticationManager {
        return ProviderManager(listOf(credentialsAuthProvider(), credentialsAuthProvider2()))
    }

    @Bean
    fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http.csrf().disable().cors().disable()
        http.authorizeRequests()
            .antMatchers("/login", "/register").permitAll().anyRequest().authenticated().and().sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
        return http.build()
    }
}
