ConversionPattern參數的格式含義
格式名 含義
%c 輸出日誌資訊所屬的類的全名
%d 輸出日誌時間點的日期或時間，默認格式為ISO8601，也可以在其後指定格式，比如：%d{yyy-MM-dd HH:mm:ss }，輸出類似：2002-10-18- 22：10：28
%f 輸出日誌資訊所屬的類的類名
%l 輸出日誌事件的發生位置，即輸出日誌資訊的語句處於它所在的類的第幾行
%m 輸出代碼中指定的資訊，如log(message)中的message
%n 輸出一個回車換行符，Windows平臺為“rn”，Unix平臺為“n”
%p 輸出優先順序，即DEBUG，INFO，WARN，ERROR，FATAL。如果是調用debug()輸出的，則為DEBUG，依此類推
%r 輸出自應用啟動到輸出該日誌資訊所耗費的毫秒數
%t 輸出產生該日誌事件的線程名
Level : OFF、FATAL、ERROR、WARN、INFO、DEBUG、ALL
