本文整理了Java中org.springframework.beans.factory.config.BeanDefinition类的一些代码示例，展示了BeanDefinition类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。BeanDefinition类的具体详情如下：
包路径：org.springframework.beans.factory.config.BeanDefinition
类名称：BeanDefinition

BeanDefinition介绍

[英]A BeanDefinition describes a bean instance, which has property values, constructor argument values, and further information supplied by concrete implementations.

This is just a minimal interface: The main intention is to allow a BeanFactoryPostProcessor such as PropertyPlaceholderConfigurerto introspect and modify property values and other bean metadata.

@Override
