ConfigurationPropertiesBean,然后调用内部方法bind进行绑定,先看一下ConfigurationPropertiesBean的get方法: public static ConfigurationPropertiesBean...: private static ConfigurationPropertiesBean create(String name, Object instance, Class<?...= null) { bindTarget = bindTarget.withExistingValue(instance); } return new ConfigurationPropertiesBean...言归正传,回到前边调用私有方法bind进行属性绑定的调用: private void bind(ConfigurationPropertiesBean bean) { if (bean == null...> bind(ConfigurationPropertiesBean propertiesBean) { Bindable<?
继续探究postProcessBeforeInitialization方法 我们点开ConfigurationPropertiesBean.get(this.applicationContext, bean..., beanName)，发现这样一个方法： public static ConfigurationPropertiesBean get(ApplicationContext applicationContext...(ApplicationContext applicationContext, Object bean, String beanName)是用来返回一个ConfigurationPropertiesBean...> type, Method factory)最终创建了这样一个ConfigurationPropertiesBean。...再看bind方法 现在让我们重回bind(ConfigurationPropertiesBean.get(this.applicationContext, bean, beanName)); if
如果没有带参数的构造器则再通过 setters 注入； 怎么判断是通过 setters 注入还是构造器注入，请看这个类的源码： org.springframework.boot.context.properties.ConfigurationPropertiesBean.BindMethod

ConfigurationBeanFactoryMetadata赞成ConfigurationPropertiesBean。
Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { bind(ConfigurationPropertiesBean.get
postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { bind(ConfigurationPropertiesBean.get...(this.applicationContext, bean, beanName)); return bean; } private void bind(ConfigurationPropertiesBean...> bind(ConfigurationPropertiesBean propertiesBean) { Bindable<?
