在我的项目中，我使用了一些不同的记录器，它们都有一个FileHandler和一个ConsoleHandler。我创建这些记录器下面的类：ConsoleHandler将信息记录到控制台，尽管日志级别是警告
public class Logging {
static {
System.setProperty("java.util.logging.config.file", "properties/logging.properties");
try {
LogManager.getLogManager().readConfiguration();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* Method to create a new logger using java.util.logging.
* @param name The name of the logger.
* @param logLevelFile The log level for writing into the log file.
* @param logLevelConsole The log level for writing on the console.
* @param logToFile True, if file logging shall be active.
* @param logToConsole True, if console logging shall be active.
* @return The new logger instance.
*/
public static Logger createLogger(String name, Level logLevelFile, Level logLevelConsole, boolean logToFile, boolean logToConsole) {
Logger logger = Logger.getLogger(name);
logger.setLevel(Level.ALL);
logger.setUseParentHandlers(false);
if (logToFile) {
final Handler fileHandler;
try {
fileHandler = new FileHandler("log/" + name + ".log");
fileHandler.setLevel(logLevelFile);
logger.addHandler(fileHandler);
// close file handler, so that *.lck files will be deleted by
// JVM
Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
@Override
public void run() {
fileHandler.close();
}
}));
} catch (SecurityException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
if (logToConsole) {
// remove existing console handlers
Handler[] handlers = logger.getHandlers();
for (Handler handler : handlers) {
if (handler.getClass() == ConsoleHandler.class)
logger.removeHandler(handler);
}
Handler consoleHandler = new ConsoleHandler();
consoleHandler.setLevel(logLevelConsole);
logger.addHandler(consoleHandler);
}
return logger;
}
}
正如你所看到的，每个记录器获取一个布尔，是否应该记录到一个文件，并到控制台。取决于可以设置哪个级别应该被记录到控制台或文件中。
我logging.properties看起来像：
handlers = java.util.logging.FileHandler, java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format = [%1$td.%1$tm.%1$tY-%1$tH:%1$tM:%1$tS] [%2$s] %4$s: %5$s %n
# approximate amount of bytes to write to a log file, before rotating to a new file
java.util.logging.FileHandler.limit = 500000
# number of log files to use in the log file rotation
java.util.logging.FileHandler.count = 0
# whether or not the FileHandler should append to an existing file or not (true or false)
java.util.logging.FileHandler.append = false
我初始化我的伐木工人如下：
Logging.createLogger(Properties.getGeneralLoggerName(), Level.INFO, Level.INFO, true, true);
Logging.createLogger(Properties.getBluetoothLoggerName(), Level.INFO, Level.INFO, true, true);
Logging.createLogger(Properties.getStrategicProcessesLoggerName(), Level.INFO, Level.WARNING, true, true);
Logging.createLogger(Properties.getNetworkLoggerName(), Level.INFO, Level.WARNING, true, true);
Logging.createLogger(Properties.getGPIOLoggerName(), Level.INFO, Level.WARNING, true, true);
Logging.createLogger(Properties.getFatigueDetectionLoggerName(), Level.INFO, Level.WARNING, true, true);
Logging.createLogger(Properties.getGPSACCLoggerName(), Level.INFO, Level.WARNING, true, true);
的问题是，例如过去的记录器不记录仅显示警告进控制台，还有信息日志。在我的Mac电脑上，这一切都正常，但是当我在嵌入式系统（带有Ubuntu 14.04的Odroid U3）上使用此代码时，它失败了，控制台输出很大。不是将输出记录到文件中，而是将它们登录到控制台中。
有人可以帮忙吗？
谢谢！
