SpringBoot startup error Unable to start web server; nested exception...
When creating a SpringBoot project, the dependency is loaded, but the startup error is as follows: Unable to start web server; nested exception...

I searched a lot on the Internet, and many answers were that the versions were inconsistent, but after careful inspection, the corresponding versions were modified, but this error was still reported, and the test was successful.
According to the self-test, it is an imported dependency problem: just comment it out or delete it
