如果在Spring上下文中找不到bean，如何提供自定义逻辑来搜索bean

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.BeanFactoryAware;
import org.springframework.beans.factory.config.BeanFactoryPostProcessor;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;

public class CustomBeanSearcher implements BeanFactoryPostProcessor, BeanFactoryAware {

    private BeanFactory beanFactory;

    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        this.beanFactory = beanFactory;
    }

    public Object searchBean(String beanName) {
        if (beanFactory.containsBean(beanName)) {
            return beanFactory.getBean(beanName);
        }
        // 自定义搜索逻辑，例如根据特定条件搜索bean
        // ...
        return null;
    }
}

<bean class="com.example.CustomBeanSearcher"/>

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class MyBeanConsumer {

    private CustomBeanSearcher beanSearcher;

    @Autowired
    public MyBeanConsumer(CustomBeanSearcher beanSearcher) {
        this.beanSearcher = beanSearcher;
    }

    public void doSomething() {
        Object bean = beanSearcher.searchBean("myBean");
        if (bean != null) {
            // 找到了bean，执行相应的操作
        } else {
            // 没有找到bean，执行其他逻辑
        }
    }
}
