5. When you run the program, you find the following error:

   slf4j:failed to load Class "Org.slf4j.impl.StaticLoggerBinder".
   Slf4j:defaulting to No-operation (NOP) Logger implementation, this is because the log4j and slf4j corresponding conversion packages are not added.

6. To download the log4j and slf4j packages, unzip and add four jars of log4j-1.2-api.2.11.0, log4j-api-2.11.0, log4j-core-2.11.0 and slf4j-log4j12-1.7.25 to the project.
7. Then run again, or will error: Error Statuslogger No log4j 2 configuration file found. Using The default configuration, this is because the config file for log4j is not joined. After placing the corresponding log4j2.xml in the SRC directory, the program will run normally.
