An error is reported in the XML file of eclipse. Close XML validation

Eclipse turns off English spell checking and XML validation

To solve the problem, the servlet can run, but the XML file is red

Mode 1:

Windows–> Preferences–> XML –> XML Files –> Validate

Find validate and uncheck build

Mode 2:

Windows–> Preferences–> XML(Wild Web Developer)-> Validate& Resolution

Cancel enable validate

Or change both enable namespaces validate and enable schema based} validate to never

Then click apply and it will be OK

The first one, I don’t know whether it’s my eclipse version or something. I didn’t find that one. The second one can solve this problem. I hope it can help you!!
