为什么Spring引导使用来自不同包的线程来处理请求？

Question

所以,我只是按照本教程来设置一些基本的身份验证.

在查看日志时,我有一个关于最新情况的问题.这是日志片段:

为了生成这些日志,我所做的只是登录/退出两次.我的问题是,为什么第二次尝试使用不同类型的线程？我第一次登录时使用了一个nio线程,第二次使用了一个io线程.有关为什么会发生这种情况或如何配置它的任何信息都会很棒.

Answer 1

Spring Boot的默认日志模式允许15个字符作为线程的名称.当名称太长时,它会通过从头开始删除字符来缩短名称的长度.nio-8080-exec-10是16个字符长,所以删除第一个字符io-8080-exec-10.
