The reason I appear is a problem with the package
Error during artifact deployment. See server log for details.
Many people can't find this, there are 2 reasons:
1. Some jar packages are not recognized, and tomcat is not configured properly!
Second, this general code is wrong:
In addition to looking at the server's error, don't forget to look at the tomcat localhost Log log file!
For example, I am adding a new entity class here, but I have not added a record in application-hibernate, all errors are reported!
