有谁知道为什么它会引发这个异常？

答案 1

当您尝试在未启用 https 的终结点上执行来自客户端的 https 请求时，可能会发生此异常。当服务器需要原始数据时，客户端将加密请求数据。

在客户端 url 中将 https:// 更改为 http://。

答案 2

另一种情况：SpringBoot和Tomcat默认使用端口8080或8888。我有一个Jupyter Notebook同时运行，它的url路径中有一个令牌和一些随机字符。无论如何：当 jupyter 笔记本服务器关闭时，笔记本仍在尝试发出请求。

如果遇到此错误：请检查是否正在运行另一个应用程序，该应用程序正在生成 Web 服务器或与此类端口上的 Web 服务器通信。
