我正在尝试使用配置文件自动连接服务类中的密码编码器：

@Configuration
@EnableWebSecurity
class SecurityConfiguration : WebSecurityConfigurerAdapter() {

@Bean
fun passwordEncoder(): PasswordEncoder {
    return BCryptPasswordEncoder()
}

intellij将@autowired var passwordencoder检测为autowired的候选。

@Service
class userServiceImpl : UserService {

@Autowired
private lateinit var passwordEncoder : PasswordEncoder

我知道调用配置是因为调用了配置文件的其他元素。
