The reason for this is that there is no jar specified in the Pom.xml in the Lib directory of the Tomcat counterpart, but there are jar packages that are imported through the normal method, the workaround is as follows:

1, right-click the project, select Properties, and then select Deployment Assembly:

2. Click Add ...

Then check: Java Build Path Entries, click next>

Select Maven Dependencies, then Finish, Ok.
