Eclipse launches Tomcat after 404 error

Problem description

After you deploy the Web project in Eclipse, you find that Tomcat can start, but access the http://localhost:8080 address 404 error. Instead of using Eclipse to start Tomcat, it is OK to start Tomcat directly by using the Bin directory under the Tomcat installation directory.

Solution:

Under Eclipse's Server page, remove all items under the Tomcat service (right-click->remove)

Right-click on the Tomcat server->clean

Then double-click on the Tomcat server and configure it as follows.

Once configured, add the required items to the Tomcat service.

Then run it and you'll find that the problem has been solved.
