在上述代码中,当Spring尝试创建MyService实例时,如果构造函数参数不匹配或其他配置错误,就会抛出BeanInstantiationException。 二、可能出错的原因 导致org.springframework.beans.BeanInstantiationException报错的原因有很多,以下是常见的几种: 构造函数参数不匹配:Spring在实例化bean时,未能找到匹配的构造函数。 依赖缺失:某些...

@EnableAsync开启时它会向容器内注入AsyncAnnotationBeanPostProcessor,它是一个BeanPostProcessor,实现了postProcessAfterInitialization方法。此处我们看代码,创建代理的动作在抽象父类AbstractAdvisingBeanPostProcessor上: // @since 3.2 注意:@EnableAsync在Spring3.1后出现// 继承自ProxyProcessorSupport,所以具有动态代理相...
