Note: Some details of this article have not been written. This article mainly writes about important links and points that need attention.

New Project

Select Gradle, check java and web. After that, set the project path and name, so I won't go into details here.

Import the required packages under the build.gradle file and refresh it.

Post the code for each class

Configure Tomcat

First configure Tomcat, the following is the configured interface

Run the project and visit http://localhost:8080/home/

What is needed here is to set the Application Context in the configuration of Tomcat. For example, if the Application Context is "/home", then the root address of the server of the project is:

http://localhost:8080/home/ , then to display the home.jsp interface should be: http://localhost:8080/home/ home .
