输出以下信息
Usage: java org.apache.logging.log4j.core.tools.Generate$CustomLogger className LEVEL1=
intLevel1 [LEVEL2=intLevel2...]
Where className is the fully qualified class name of the custom/extended logger to generate,
followed by a space-separated list of custom log levels.
For each custom log level, specify NAME=intLevel (without spaces).
