如何在Spring Boot的@PostConstruct中添加动态创建的bean

import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.GenericBeanDefinition;
import org.springframework.stereotype.Component;

@Component
public class DynamicBeanCreator implements InitializingBean {

    @Autowired
    private BeanDefinitionRegistry beanDefinitionRegistry;

    @Override
    public void afterPropertiesSet() throws Exception {
        // 创建动态bean的定义
        GenericBeanDefinition beanDefinition = new GenericBeanDefinition();
        beanDefinition.setBeanClass(DynamicBean.class);

        // 注册动态bean的定义
        beanDefinitionRegistry.registerBeanDefinition("dynamicBean", beanDefinition);
    }
}
