类 Log

java.lang.Object
  org.eclipse.jetty.util.log.Log

public class Log
extends Object

Logging. This class provides a static logging interface. If an instance of the org.slf4j.Logger class is found on the classpath, the static log methods are directed to a slf4j logger for "org.eclipse.log". Otherwise the logs are directed to stderr.

The "org.eclipse.jetty.util.log.class" system property can be used to select a specific logging implementation.

If the system property org.eclipse.jetty.util.log.IGNORED is set, then ignored exceptions are logged in detail.

方法详细信息

initialized

public static boolean initialized()

setLog

public static void setLog(Logger log)

getLog

@Deprecated
public static Logger getLog()

已过时。 anonymous logging is deprecated, use a named Logger obtained from getLogger(String)

getRootLogger

public static Logger getRootLogger()

Get the root logger.

返回：

the root logger

setLogToParent

public static void setLogToParent(String name)

Set Log to parent Logger.

If there is a different Log class available from a parent classloader, call getLogger(String) on it and construct a LoggerLog instance as this Log's Logger, so that logging is delegated to the parent Log.

This should be used if a webapp is using Log, but wishes the logging to be directed to the containers log.

If there is not parent Log, then this call is equivalent to

   Log.setLog(Log.getLogger(name));
 

参数：

name - Logger name

debug

@Deprecated
public static void debug(Throwable th)

已过时。 anonymous logging is deprecated, use a named Logger obtained from getLogger(String)

debug

@Deprecated
public static void debug(String msg)

已过时。 anonymous logging is deprecated, use a named Logger obtained from getLogger(String)
