Accessing spring beans in static method

BeanRegistry.kt

@Configuration(proxyBeanMethods = false)
class BeanRegistry : ApplicationContextAware {
    companion object {
        private lateinit var applicationContext: ApplicationContext

        // 타입으로 빈을 가져옵니다
        fun <T : Any> getBean(type: KClass<T>): T =
            applicationContext.getBean(type.java)
        // 이름과 타입으로 빈을 가져옵니다
        fun <T : Any> getBean(name: String, type: KClass<T>): T =
            applicationContext.getBean(name, type.java)  //type이 중복될 때 name으로 구분
    }

    override fun setApplicationContext(applicationContext: ApplicationContext) {

        BeanRegistry.applicationContext = applicationContext
    }
