官网springframework 5.3.20 API

概述

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 to introspect and modify property values and other bean metadata.

BeanDefinition描述一个bean实例，该实例具有属性值、构造函数参数值以及具体实现提供的进一步信息。

这只是一个最小的接口：主要目的是允许BeanFactoryPostProcessor内省和修改属性值和其他bean元数据。

方法

setBeanClassName

The class name can be modified during bean factory post-processing, typically replacing the original class name with a parsed variant of it.

用于指定bean的类型

setScope

isLazyInit

Return whether this bean should be lazily initialized, i.e. not eagerly instantiated on startup. Only applicable to a singleton bean.

返回这个bean是否延迟初始化。

setDependsOn
