Almost all the Internet queries have problems. There are files in the meta-inf folder of the packaged jar or war.JBoss is trying to process these files or doesn’t want to process them there.

However, I found that my meta-inf folder was empty and there was no * RSA,*.DSA,*.SF and other documents are hard to understand
I have also tried to repackage and replace the Tomcat version, but this problem has not been solved.

Finally, I thought that the project is divided into modules. Are there these files in the jar package generated by the referenced submodule? Finally, I checked one by one and finally found the problem:
there are these * RSA,*. DSA,*. SF files


remove these files from the jar package:

zip -d <jar file name>.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF

But this is a temporary solution but not a permanent solution. The problem will still occur in the next packaging. Finally, go to the pom.xml file to exclude META-INF/*.SF and other files
