在SpringBoot启动时会在自动配置解析类ConfigurationClassPostProcessor中获取ImportSelector的类并执行ImportSelector#selectImports方法。ImportSelector#selectImports的返回值表示自动配置的配置类,SpringBoot的自动配置原理就是这样做的。 AsyncConfigurationSelector类定义: publicclassAsyncConfigurationSelectorextendsAdviceMo...

非阻塞,就是调用我(s端被调用者,函数),我(s端被调用者,函数)立即返回,这样的好处是调用者得到返回后可以继续做其他操作,实际的计算结果之后**通过select通知调用者。 同步/异步是由c端自己控制,但是S端是否阻塞/非阻塞, C端完全不需要关心. 既然异步IO优势这么明显,那在所有项目里面只使用这一种不就好了?什么...
