6. Configure your own project
6.1 Find webapps in the Tomcat directory, and then create a new project name in it (not in Chinese)
6.2 Copy the WEB-INF folder under the ROOT file under webapps to your own project
6.3 Then you can Put the files you need. For example, I put a json file here. 6.4 Access the
files in the project. For other terminal access, replace localhost with the ip of the computer where Tomcat is built (windows can enter ipconfig through the terminal), for example: http://192.168.16.101:8080/xxx/test.json
