java - 无法自动接线。找不到 'AuthenticationProvider' 类型的 bean

Question

我无法在我的 SecurityConfig 类中 Autowiring AuthenticationProvider Spring 框架实例。这很奇怪，因为我已经包含了必要的导入，并且 UserDetailsS​​ervice(另一个 Spring Framework 类)可以 Autowiring 而没有任何问题。这是我的代码:

import org.springframework.beans.factory.annotation.Autowired
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.security.authentication.AuthenticationProvider
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity
import org.springframework.security.config.annotation.web.builders.HttpSecurity
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter
import org.springframework.security.core.userdetails.UserDetailsService
import org.springframework.security.web.authentication.RememberMeServices
import org.springframework.security.web.authentication.rememberme.TokenBasedRememberMeServices

@Configuration
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
class SecurityConfig : WebSecurityConfigurerAdapter() {
    companion object {
        private const val REMEMBER_ME_KEY = "basdrwerdadev$#@safasfewrahl"
    }

    @Autowired private lateinit var authenticationProvider: AuthenticationProvider
    @Autowired private lateinit var userDetailsService: UserDetailsService
    ...

也许我缺少依赖项？我添加了 Spring 安全依赖项

我要检查的前两件事是:
i)您的自定义身份验证提供程序是否被注释为服务/组件(即 spring 可以查看和管理它吗？)
ii) 它是否扩展了 spring 的 AuthenticationManager 接口(interface)？
