要将日期格式更改为YYYYMMDD，您需要修改"java.util.logging.SimpleFormatter.format"属性的值。
尝试将其更改为以下内容：
System.setProperty("java.util.logging.SimpleFormatter.format", "[%1$tY%1$tm%1$td %1$tT] [%4$-7s] %5$s %n");
在这个格式中，%1$tY将给您4位数的年份，%1$tm将给您2位数的月份，%1$td将给您2位数的日期。这样，日期将以所需的格式显示。
英文:
To change the format of the date to YYYYMMDD, you need to modify the value of the "java.util.logging.SimpleFormatter.format" property.
Try changing it to the following:
System.setProperty("java.util.logging.SimpleFormatter.format", [%1$tY%1$tm%1$td %1$tT] [%4$-7s] %5$s %n");
In this format, %1$tY will give you the 4-digit year, %1$tm will give you the 2-digit month, and %1$td will give you the 2-digit day. This way, the date will be displayed in the desired format.
