&【04】invokeBeanFactoryPostProcessors方法调用

invokeBeanFactoryPostProcessors 方法调用

在xmlBeanDefinition解析后，实例化之前，可用此接口完成对beanDefinition的动态修改。

BeanDefinitionRegistryPostProcessor 方法调用

代码示例：

import org.springframework.beans.BeansException;
import org.springframework.beans.MutablePropertyValues;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.support.BeanDefinitionRegistry;
import org.springframework.beans.factory.support.BeanDefinitionRegistryPostProcessor;
import org.springframework.beans.factory.support.GenericBeanDefinition;
import org.springframework.stereotype.Component;

@Component
public class BeanPro implements BeanDefinitionRegistryPostProcessor {

    @Override
    public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry registry) throws BeansException {
        GenericBeanDefinition genericBeanDefinition = new GenericBeanDefinition();
        genericBeanDefinition.setBeanClass(TestBean.class);
        MutablePropertyValues propertyValues = genericBeanDefinition.getPropertyValues();
        propertyValues.add("myName","xxxx");
        registry.registerBeanDefinition("testBean",genericBeanDefinition);
    }

    /**
     * 需要用到容器对象 来修改某些东西
     */
    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {

    }
}
