記錄級別
Java Logging Api 有 7 個級別 。降序的級別為:
SEVERE
(最高價值)WARNING
INFO
CONFIG
FINE
FINER
FINEST
(最低價值)
預設級別為 INFO
(但這取決於系統並使用虛擬機器)。
注意 :還有 OFF
(可用於關閉登出)和 ALL
(OFF
的對位)。
程式碼示例:
import java.util.logging.Logger;
public class Levels {
private static final Logger logger = Bukkit.getLogger();
public static void main(String[] args) {
logger.severe("Message logged by SEVERE");
logger.warning("Message logged by WARNING");
logger.info("Message logged by INFO");
logger.config("Message logged by CONFIG");
logger.fine("Message logged by FINE");
logger.finer("Message logged by FINER");
logger.finest("Message logged by FINEST");
// All of above methods are really just shortcut for
// public void log(Level level, String msg):
logger.log(Level.FINEST, "Message logged by FINEST");
}
}
預設情況下,執行此類將僅輸出級別高於 CONFIG
的訊息:
Jul 23, 2016 9:16:11 PM LevelsExample main
SEVERE: Message logged by SEVERE
Jul 23, 2016 9:16:11 PM LevelsExample main
WARNING: Message logged by WARNING
Jul 23, 2016 9:16:11 PM LevelsExample main
INFO: Message logged by INFO
