Eclipse is a magic problem.

Today, I wrote a JSP program, but it never runs after it is written. The error "HTTP status 404" is prompted, and people are crazy.

Depend! How can this broken thing be so difficult to serve!

I thought about it. Some time ago, eclipse was installed in the root directory of the hard disk, and it was placed under the Program Files directory when I installed it again. So put it here, in order that the root directory of the hard disk looks simple, everything is put in the root directory is messy.

As a result, eclipse is stored in the root directory of the hard disk. The magic thing happened. TMD, the problem was solved in this way. It's a strange thing !!
