方法详细资料

getName

java.lang.String getName()

Return the name of this Logger instance.

返回:

name of this logger instance

isTraceEnabled

boolean isTraceEnabled()

Is the logger instance enabled for the TRACE level?

返回:

True if this Logger is enabled for the TRACE level, false otherwise.

trace

void trace(java.lang.String msg)

Log a message at the TRACE level.

参数:

msg - the message string to be logged

trace

void trace(java.lang.String format,
           java.lang.Object... arguments)

Log a message at the TRACE level according to the specified format and arguments.

This form avoids superfluous string concatenation when the logger is disabled for the TRACE level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for TRACE.

参数:

format - the format string

arguments - a list of 3 or more arguments

trace

void trace(java.lang.String msg,
           java.lang.Throwable t)

Log an exception (throwable) at the TRACE level with an accompanying message.

参数:

msg - the message accompanying the exception

t - the exception (throwable) to log

isDebugEnabled

boolean isDebugEnabled()

Is the logger instance enabled for the DEBUG level?

返回:

True if this Logger is enabled for the DEBUG level, false otherwise.

debug

void debug(java.lang.String msg)

Log a message at the DEBUG level.

参数:

msg - the message string to be logged

debug

           java.lang.Object... arguments)

Log a message at the DEBUG level according to the specified format and arguments.

This form avoids superfluous string concatenation when the logger is disabled for the DEBUG level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for DEBUG.

参数:

format - the format string

arguments - a list of 3 or more arguments

debug

void debug(java.lang.String msg,
           java.lang.Throwable t)

msg - the message accompanying the exception

t - the exception (throwable) to log

isInfoEnabled

boolean isInfoEnabled()

Is the logger instance enabled for the INFO level?

参数:

msg - the message string to be logged

info

void info(java.lang.String format,
          java.lang.Object... arguments)

Log a message at the INFO level according to the specified format and arguments.

参数:

format - the format string

arguments - a list of 3 or more arguments

info

void info(java.lang.String msg,
