2. My application.properties file

#Set the port number
server.port=8089 #wrong match here
# Configure the access path of the project
server.servlet.context-path=qingfeng #wrong match here

3. My application.properties file is incorrectly configured and should be changed to the following

#Set the port number
server.port=8089  
# Configure the access path of the project
server.servlet.context-path=/qingfeng/ #correct

the modified access path can run normally
